They supervise a staff which may in­ clude engineers, scientists, technicians, computer specialists, data processing workers, along with support personnel. Engineering, science, and data processing managers determine scientific and technical goals within broad outlines provided by top management. These goals may include the redesign of an industrial machine, improvements in manufacturing processes, the develop­ ment of a large computer program, or advances in basic scientific re­ search. Managers make detailed plans for the accomplishment of these goals—for example, they may develop the overall concepts of new products or identify problems standing in the way of project completion. They forecast costs and equipment and personnel needs for projects and programs. They hire and assign scientists, engi­ neers, technicians, computer specialists, data processing workers, and support personnel to carry out specific parts of the projects, su­ pervise their work, and review their designs, programs, and reports. Managers coordinate the activities of their unit with other units or organizations. They confer with higher levels of management; with financial, industrial production, marketing, and other manag­ ers; and with contractors and equipment suppliers. They also estab­ lish working and administrative procedures and policies. Engineering managers direct and coordinate production, opera­ tions, quality assurance, testing, or maintenance in industrial plants; or plan and coordinate the design and development of machinery, products, systems, and processes. Many are plant engineers, who di­ rect and coordinate the maintenance, operation, design, and instal­ lation of equipment and machinery in industrial plants. Others man­ age research and development activities that produce new products and processes or improve existing ones. Natural science managers oversee activities in agricultural sci­ ence, chemistry, biology, geology, meteorology, or physics. They manage research and development projects and direct and coordi­ nate testing, quality control, and production activities in industrial plants. Electronic data processing managers direct, plan, and coordinate data processing activities. Top level managers direct all computerrelated activities in an organization. Others manage computer oper­ ations, software development, or data bases. They analyze the data processing requirements of their organization and assign, schedule, and review the work of systems analysts, computer programmers, and computer operators. They determine computer hardware re­ quirements, evaluate equipment options, and make purchasing deci­ sions. Some engineering, science, and data processing managers head a section of perhaps 3 to 10 or more scientists, engineers, or computer professionals. Above them are heads of divisions composed of a number of sections, with as many as 15 to 50 scientists or engineers. A few are directors of large laboratories or directors of research. Working Conditions Engineering, science, and data processing managers spend most of their time in an office. Some managers, however, may also work in laboratories or industrial plants, where they normally are exposed  2 Federal Reserve Bank of St. Louis  Engineering managers direct the research, development, and manufacture of a product. to the same conditions as research scientists and may occasionally be exposed to the same conditions as production workers. Most work at least 40 hours a week and may work much longer on occa­ sion to meet project deadlines. Some may experience considerable pressure to meet technical or scientific goals within a short time or within a tight budget. Employment Engineering, science, and data processing managers held about 337,000 jobs in 1992. Although these managers are found in almost all industries, nearly two-fifths are employed in manufacturing, es­ pecially in the industrial machinery and equipment, electrical and electronic equipment, transportation equipment, instruments, and chemicals industries. They also work for engineering, management, and computer and data processing services companies. Others work for government, colleges and universities, and nonprofit research organizations. The majority are most likely engineering managers, often managing industrial research, development, and design projects. Training, Other Qualifications, and Advancement Experience as an engineer, mathematician, natural scientist, or computer professional is the usual requirement for becoming an en­ gineering, science, or data processing manager. Consequently, edu­ cational requirements are similar to those for scientists, engineers, and data processing professionals. Engineering managers start as engineers. A bachelor’s degree in engineering from an accredited engineering program is acceptable for beginning engineering jobs, but many engineers increase their chances for promotion to manager by obtaining a master’s degree in engineering or business administration. A degree in business admin­ istration or engineering management is especially useful for becom­ ing a general manager. Natural science managers usually start as a chemist, physicist, bi­ ologist, or other natural scientist. Most natural scientists engaged in basic research have a Ph.D. degree. Some in applied research and other activities may have lesser degrees. First-level science manag­ ers are usually specialists in the work they supervise. For example, the manager of a group of physicists doing optical research is almost always a physicist who is an expert in optics. Most data processing managers have been systems analysts, al­ though some may have experience as programmers, operators, or in other computer specialties. There is no universally accepted way of  For sale by the U.S. Government Printing Office Superintendent of Documents, Mail Stop: SSOP, Washington, DC 20402-9328  ISBN 0-16-043050-X  preparing for a job as a systems analyst. Many have degrees in com­ puter or information science, computer information systems, or data processing and have experience as computer programmers. A bachelor’s degree is usually required and a graduate degree often is preferred. A typical career advancement progression in a large or­ ganization would be from programmer to programmer/analyst, to systems analyst, and then to project leader or senior analyst. The first real managerial position might be as project manager, program­ ming supervisor, systems supervisor, or software manager. In addition to educational requirements, scientists, engineers, or computer specialists generally must have demonstrated above-aver­ age technical skills to be considered for promotion to manager. Superiors also look for leadership and communication skills, as well as managerial attributes such as the ability to make rational deci­ sions, to manage time well, to organize and coordinate work effec­ tively, to establish good working and personal relationships, and to motivate others. Also, a successful manager must have the desire to manage. Many scientists, engineers, and computer specialists want to be promoted but actually prefer doing technical work. Some scientists and engineers become managers in marketing, personnel, purchasing, or other areas or become general managers. Job Outlook Employment of engineering and science managers is expected to in­ crease faster than the average for all occupations through the year 2005. Opportunities for those who wish to become engineering, sci­ ence, and data processing managers should be closely related to the growth of the occupations they supervise and the industries in which they are found. (See the statements on natural scientists, engi­ neers, computer programmers, and computer scientists and systems analysts elsewhere in the Handbook.) Underlying much of the growth of managers in science and engi­ neering are competitive pressures and advancing technologies which force companies to update and improve products more fre­ quently. Research and investment in plants and equipment to ex­ pand output of goods and services and to raise productivity also will add to employment requirements for science and engineering man­ agers involved in research and development, design, and the opera­ tion and maintenance of production facilities. Many of the industries which employ engineers and scientists de­ rive a large portion of their business from defense contracts. Because defense expenditures are being reduced, employment growth and job outlook for managers in these industries may not be as strong in the future as in the 1980’s, when defense expenditures were increas­ ing. Employment of data processing managers will increase rapidly due to the fast paced expansion of the computer and data processing services industry and the increased employment of computer sys­ tems analysts. Large computer centers are consolidating or closing as small computers become more powerful, and more automated systems are resulting in fewer opportunities for data processing managers at computing centers. However, as the economy expands and as advances in technology lead to broader applications for com­ puters, opportunities should increase and employment growth should be brisk. Despite growth in employment, most job openings will result from the need to replace workers who leave the occupation. Because many engineers, natural scientists, and computer specialists are eli­ gible for management and seek promotion, there can be substantial competition for these openings. Earnings Earnings for engineering, science, and data processing managers vary by specialty and level of management. Science and engineering managers had average salaries that ranged from $50,000 to well over $100,000 for the most senior managers in large organizations, ac­ cording to the limited data available. Data processing managers had salaries that ranged from $35,000 to $80,000. Managers often earn Federal Reserve Bank of St. Louis  about 15 to 25 percent more than those they directly supervise, al­ though there are cases where some employees are paid more than the manager who supervises them, especially in research. In addition, engineering, science, and data processing managers, especially those at higher levels, often are provided more benefits than non-managerial workers in their organizations. Higher level managers often are provided with expense accounts, stock option plans, and bonuses. Related Occupations The work of engineering, science, and data processing managers is closely related to that of engineers, natural scientists, computer per­ sonnel, and mathematicians. It is also related to the work of other managers, especially general managers and top executives.

Engineers Nature of the Work Engineers apply the theories and principles of science and mathe­ matics to the economical solution of practical technical problems. Often their work is the link between a scientific discovery and its ap­ plication. Engineers design machinery, products, systems, and processes for efficient and economical performance. They design in­ dustrial machinery and equipment for manufacturing goods and de­ fense and weapons systems for the Armed Forces. Many engineers design, plan, and supervise the construction of buildings, highways, and rapid transit systems. They also design and develop consumer products and systems for control and automation of manufacturing, business, and management processes. Engineers consider many factors in developing a new product. For example, in developing an industrial robot, they determine pre­ cisely what function it needs to perform; design and test compo­ nents; fit them together in an integrated plan; and evaluate the de­ sign’s overall effectiveness, cost, reliability, and safety. This process applies to products as different as computers, gas turbines, genera­ tors, helicopters, and toys. In addition to design and development, many engineers work in testing, production, or maintenance. They supervise production in factories, determine the causes of breakdowns, and test manufac­ tured products to maintain quality. They also estimate the time and cost to complete projects. Some work in engineering management or in sales, where an engineering background enables them to discuss the technical aspects of a product and assist in planning its installa­ tion or use. (See the statements on engineering, science, and data processing managers and manufacturers’ and wholesale sales repre­ sentatives elsewhere in the Handbook.) Most engineers specialize; more than 25 major specialties are rec­ ognized by professional societies. Within the major branches are nu­ merous subdivisions. Structural, environmental, and transportation engineering, for example, are subdivisions of civil engineering. Engi­ neers also may specialize in one industry, such as motor vehicles, or in one field of technology, such as propulsion or guidance systems. This section, which contains an overall discussion of engineering, is followed by separate sections on 10 engineering branches: Aero­ space; chemical; civil; electrical and electronics; industrial; mechan­ ical; metallurgical, ceramic, and materials; mining; nuclear; and petroleum engineering. Branches of engineering not covered in detail, but in which there are established college programs include: Architectural engineering—the design of a building’s internal sup­ port structure; biomedical engineering—the application of engineer­ ing to medical and physiological problems; environmental engineer­ ing—a small but growing discipline involved with identifying, 3  solving, and alleviating environmental problems; and marine engi­ neering—the design and installation of ship machinery and propul­ sion systems. Engineers in each branch have knowledge and training that can be applied to many fields. Electrical and electronics engineers, for example, work in the medical, computer, missile guidance, and power distribution fields. Because there are many separate problems to solve in a large engineering project, engineers in one field often work closely with specialists in scientific, other engineering, and business occupations. Engineers often use computers to simulate and test how a ma­ chine, structure, or system operates. Many engineers also use com­ puter-aided design systems to produce and analyze designs. They also spend a great deal of time writing reports and consulting with other engineers. Complex projects require many engineers, each working with a small part of the job. Supervisory engineers are re­ sponsible for major components or entire projects. Working Conditions Many engineers work in laboratories, industrial plants, or construc­ tion sites, where they inspect, supervise, or solve onsite problems. Others work in an office almost all of the time. Engineers in branches such as civil engineering may work outdoors part of the time. A few engineers travel extensively to plants or construction sites. Many engineers work a standard 40-hour week. At times, dead­ lines or design standards may bring extra pressure to a job. When this happens, engineers may work long hours and experience con­ siderable stress. Employment In 1992, engineers held 1,354,000 jobs. Just under one-half of all en­ gineering jobs were located in manufacturing industries—mostly in electrical and electronic equipment, aircraft and parts, machinery, scientific instruments, chemicals, motor vehicles, fabricated metal products, and primary metals industries. In 1992, 713,000 jobs were in nonmanufacturing industries, primarily in engineering and archi­ tectural services, research and testing services, and business ser­ vices, where firms designed construction projects or did other engi­ neering work on a contract basis for organizations in other parts of the economy. Engineers also worked in the communications, utili­ ties, and construction industries. Federal, State, and local governments employed about 190,000 engineers. Over half of these were in the Federal Government, mainly in the Departments of Defense, Transportation, Agriculture, Interior, and Energy, and in the National Aeronautics and Space Administration. Most engineers in State and local government agencies worked in highway and public works departments. Some engineers are self-employed consultants. Engineers are employed in every State, in small and large cities, and in rural areas. Some branches of engineering are concentrated in particular industries and geographic areas, as discussed in state­ ments later in this chapter. Training, Other Qualifications, and Advancement A bachelor’s degree in engineering from an accredited engineering program is usually required for beginning engineering jobs. College graduates with a degree in a physical science or mathematics may occasionally qualify for some engineering jobs, especially in engi­ neering specialties in high demand. Most engineering degrees are granted in branches such as electrical, mechanical, or civil engineer­ ing. However, engineers trained in one branch may work in another. This flexibility allows employers to meet staffing needs in new tech­ nologies and specialties in short supply. It also allows engineers to shift to fields with better employment prospects, or ones that match their interests more closely. In addition to the standard engineering degree, many colleges of­ fer degrees in engineering technology, which are offered as either 2or 4-year programs. These programs prepare students for practical design and production work rather than for jobs that require more 4 Federal Reserve Bank of St. Louis  Electrical engineering accounts for more than one-fourth of all engineers.

Graduates of 4year technology programs may get jobs similar to those obtained by graduates with a bachelor’s degree in engineering. In fact, some em­ ployers regard them as having skills between those of a technician and an engineer.  The number of degrees granted in engineering continues its declining trend.

Many engineers obtain a master’s degree to learn new technology, to broaden their education, and to enhance promotion opportunities. Nearly 390 colleges and universities offer a bachelor’s degree in engineering, and nearly 300 colleges offer a bachelor’s degree in en­ gineering technology, although not all are accredited programs. Al­ though most institutions offer programs in the larger branches of engineering, only a few offer some of the smaller specialties. Also, programs of the same title may vary in content. For example, some emphasize industrial practices, preparing students for a job in indus­ try, while others are more theoretical and are better for students preparing to take graduate work. Therefore, students should investi­ gate curriculums and check accreditations carefully before selecting a college. Admissions requirements for undergraduate engineering schools include courses in advanced high school mathematics and the physical sciences. Bachelor’s degree programs in engineering are typically designed to last 4 years, but many students find that it takes between 4 and 5 years to complete their studies. In a typical 4-year college curricu­ lum, the first 2 years are spent studying basic sciences (mathematics, physics, and chemistry), introductory engineering, and the humani­ ties, social sciences, and English. In the last 2 years, most courses are in engineering, usually with a concentration in one branch. For example, the last 2 years of an aerospace program might include courses such as fluid mechanics, heat transfer, applied aerodynam­ ics, analytical mechanics, flight vehicle design, trajectory dynamics, and aerospace propulsion systems. Some programs offer a general engineering curriculum; students then specialize in graduate school or on the job. A few engineering schools and 2-year colleges have agreements whereby the 2-year college provides the initial engineering educa­ tion and the engineering school automatically admits students for their last 2 years. In addition, a few engineering schools have ar­ rangements whereby a student spends 3 years in a liberal arts college studying preengineering subjects and 2 years in the engineering school and receives a bachelor’s degree from each. Some colleges and universities offer 5-year master’s degree programs. Some 5- or even 6-year cooperative plans combine classroom study and practical work, permitting students to gain valuable expe­ rience and finance part of their education. All 50 States and the District of Columbia require registration for engineers whose work may affect life, health, or property, or who of­ fer their services to the public. In 1992, nearly 380,000 engineers were registered. Registration generally requires a degree from an en­ gineering program accredited by the Accreditation Board for Engi­ neering and Technology, 4 years of relevant work experience, and passing a State examination. Some States will not register people with degrees in engineering technology. Beginning engineering graduates usually do routine work under the supervision of experienced engineers and, in larger companies, may also receive formal classroom or seminar-type training. As they gain knowledge and experience, they are assigned more difficult tasks with greater independence to develop designs, solve problems, and make decisions. Engineers may become technical specialists or may supervise a staff or team of engineers and technicians. Some eventually become engineering managers or enter other managerial, management support, or sales jobs. (See the statements under execu­ tive, administrative, and managerial occupations; under sales occu­ pations; and on computer systems analysts elsewhere in the Hand­ book.) Some engineers obtain graduate degrees in engineering or business administration to improve advancement opportunities; others obtain law degrees and become patent attorneys. Many high level executives in government and industry began their careers as engineers. Engineers should be able to work as part of a team and should have creativity, an analytical mind, and a capacity for detail. In ad­ dition, engineers should be able to express themselves well—both orally and in writing. Federal Reserve Bank of St. Louis  Job Outlook Employment opportunities in engineering have been good for a number of years. They are expected to continue to be good through the year 2005 because employment is expected to increase about as fast as the average for all occupations while the number of degrees granted in engineering is expected to remain near present levels through the year 2005. Many of the jobs in engineering are related to national defense. Defense expenditures will decline in the future, so employment growth and job outlook for engineers may not be as strong as in the 1980’s, when defense expenditures were increasing. However, grad­ uating engineers will continue to be in demand for jobs in engineer­ ing and other areas, possibly even at the same time other engineers, especially defense industry engineers, are being laid off. Employers will need more engineers as they increase investment in plant and equipment to further increase productivity and expand output of goods and services. In addition, competitive pressures and advancing technology will force companies to improve and update product designs more frequently. Finally, more engineers will be needed to improve deteriorating roads, bridges, water and pollution control systems, and other public facilities. Freshman engineering enrollments began declining in 1983, and the number of bachelor’s degrees in engineering began declining in 1987. Although it is difficult to project engineering enrollments, this decline may continue through the late 1990’s because the total col­ lege-age population is projected to decline. Furthermore, the pro­ portion of students interested in engineering careers has declined as prospects for college graduates in other fields have improved and in­ terest in other programs has increased. Only a relatively small proportion of engineers leave the profes­ sion each year. Despite this, three-fourths of all job openings will arise from replacement needs. A greater proportion of replacement openings is created by engineers who transfer to management, sales, or other professional specialty occupations than by those who leave the labor force. Most industries are less likely to lay off engineers than other workers. Many engineers work on long-term research and develop­ ment projects or in other activities which may continue even during recessions. In industries such as electronics and aerospace, however, large government cutbacks in defense or research and development have resulted in layoffs for engineers. New computer-aided design systems enable engineers to produce or modify designs much more rapidly than previously. This in­ creased productivity might have resulted in fewer engineering jobs had engineers not used these systems to improve the design process. They now produce and analyze many more design variations before selecting a final one. Therefore, this technology is not expected to limit employment opportunities. It is important for engineers to continue their education through­ out their careers because much of their value to their employer de­ pends on their knowledge of the latest technology. In 1990, about 110,000 persons, or 7.5 percent of all engineers were enrolled in graduate engineering programs. The pace of technological change varies by engineering specialty and industry. Engineers in high-tech­ nology areas such as advanced electronics or aerospace may find that their knowledge becomes obsolete rapidly. Even those who con­ tinue their education are vulnerable to obsolescence if the particular technology or product they have specialized in becomes obsolete. Engineers whom employers consider not to have kept up may find themselves passed over for promotions and are particularly vulnera­ ble to layoffs. On the other hand, it is often these high-technology areas that offer the greatest challenges, the most interesting work, and the highest salaries. Therefore, the choice of engineering spe­ cialty and employer involves an assessment not only of the potential rewards but also of the risk of technological obsolescence. (The out­ look for 10 branches of engineering is discussed in separate sec­ tions.) 5  Earnings Starting salaries for engineers with the bachelor’s degree are signifi­ cantly higher than starting salaries of bachelor’s degree graduates in other fields. According to the College Placement Council, engineer­ ing graduates with a bachelor’s degree averaged about $34,000 a year in private industry in 1992; those with a master’s degree and no experience, $39,200 a year; and those with a Ph.D., $54,400. Start­ ing salaries for those with the bachelor’s degree vary by branch, as shown in the following tabulation.  Petroleum . Chemical .. Mechanical Nuclear__ Electrical.. Materials .. Industrial..

Experienced midlevel engineers with no supervisory responsibilities had median annual earnings of about $52,500, with the middle half earning between about $48,200 and $57,300 a year. Median annual earnings for engineers at senior managerial levels were about $87,000. Median annual earnings for these and other levels of engineers are shown in the following tabulation.

They de­ velop new technologies in commercial aviation, defense systems, and space exploration, often specializing in areas like structural de­ sign, guidance, navigation and control, instrumentation and com­ munication, or production methods. They also may specialize in one type of aerospace product, such as commercial transports, helicop­ ters, spacecraft, or rockets. Aerospace engineers may be experts in aerodynamics, propulsion, thermodynamics, structures, celestial mechanics, acoustics, or guidance and control systems. Employment Aerospace engineers held about 66,000 jobs in 1992. Almost 55 per­ cent were in the aircraft and parts and guided missile and space ve­ hicle manufacturing industries. Federal Government agencies, pri­ marily the Department of Defense and the National Aeronautics and Space Administration, provided more than 1 out of 10 jobs. Business services, engineering and architectural services, research and testing services, and communications equipment manufactur­ ing firms accounted for most of the remainder. California, Washington, and Texas, States with large aerospace manufacturers, have the most aerospace engineers. Job Outlook Those seeking employment as aerospace engineers are likely to face keen competition because the number of job opportunities is ex­ pected to be significantly fewer than the relatively large pool of graduates. Defense Department expenditures for military aircraft, missiles, and other aerospace systems are declining. Growth in the civilian sector, which needs to replace the present fleet of airliners with quieter and more fuel-efficient aircraft, is projected to be much slower than previously anticipated due to the financial problems of  The average annual salary for engineers in the Federal Govern­ ment in nonsupervisory, supervisory, and managerial positions was $54,422 in 1993.  Related Occupations Engineers apply the principles of physical science and mathematics in their work. Other workers who use scientific and mathematical principles include physical scientists, life scientists, computer scien­ tists, mathematicians, engineering and science technicians, and ar­ chitects.

Consequently, employment of aerospace engineers is ex­ pected to grow more slowly than the average for all occupations through the year 2005. Future growth of employment in this field could also be limited because a higher proportion of engineers in aerospace manufacturing may come from the materials, mechani­ cal, or electrical engineering fields. Most job openings will result from the need to replace aerospace engineers who transfer to other occupations or leave the labor force. Because a large proportion of aerospace engineering jobs are de­ fense related, unexpected cancellation of a defense contract and other defense expenditure cutbacks can result in layoffs of aerospace engineers.

(See introductory section of this chapter for information on train­ ing requirements and earnings.)  Chemical Engineers (D.O.T. 008.061)  Nature of the Work Chemical engineers apply the principles of chemistry and engineer­ ing to solve problems involving the production or use of chemicals. Many work in the production of chemicals and chemical products. They design equipment and develop processes for manufacturing chemicals in chemical plants, plan and test methods of manufactur­ ing the products, and supervise production. Chemical engineers also work in industries other than chemical manufacturing such as elec­ tronics or aircraft manufacturing. Because the knowledge and du­ ties of chemical engineers cut across many fields, they apply princi­ ples of chemistry, physics, mathematics, and mechanical and electrical engineering in their work. They frequently specialize in a particular operation such as oxidation or polymerization. Others specialize in a particular area such as pollution control or the pro­ duction of a specific product like automotive plastics or chlorine bleach. Employment Chemical engineers held over about 52,000 jobs in 1992. Seventy percent were in manufacturing industries, primarily in the chemical,  petroleum refining, and related industries. Most of the rest worked for engineering services, research and testing services, or consulting firms that design chemical plants or do other work on a contract ba­ sis, or worked for government agencies or as independent consul­ tants. Job Outlook Although employment in the chemical manufacturing industry is projected to grow very little through 2005, chemical engineers should find favorable job opportunities. The number of positions arising from employment growth, which is expected to be as fast as the average for all occupations through the year 2005, and the need to replace those who leave the occupation should be sufficient to ab­ sorb the number of graduates with degrees in chemical engineering and other entrants. Areas relating to the production of industrial chemicals, biotech­ nology, and materials science may provide better opportunities than other portions of the chemical industry. Much of the projected growth in employment, however, will be in nonmanufacturing in­ dustries, especially service industries.

Major spe­ cialties within civil engineering are structural, water resources, envi­ ronmental, construction, transportation, and geotechnical engineer­ ing. Many civil engineers hold supervisory or administrative posi­ tions, ranging from supervisor of a construction site to city engineer. Others may work in design, construction, research, and teaching.  ♦V |  A chemical engineer studies data describing the results of a chemical reaction trial run.

Over 40 percent of the jobs were in Federal, State, and local government agencies. Over one-third were in firms that provide engineering consulting services, primarily developing designs for new construction projects. The construction industry, public utilities, transportation, and manufac­ turing industries accounted for most of the rest. Civil engineers usually are found working near major industrial and commercial centers, often at construction sites. Some projects are situated in remote areas or in foreign countries. In some jobs, civil engineers move from place to place to work on different projects. Job Outlook Employment of civil engineers is expected to increase about as fast as the average for all occupations through the year 2005, spurred by population growth and an expanding economy. More civil engineers will be needed to design and construct higher capacity transporta­ tion, water supply, and pollution control systems, large buildings, and other structures, and repair or replace existing roads, bridges, and other public structures. Most job openings, however, will result from the need to replace civil engineers who transfer to other occu­ pations or leave the labor force. Because construction and related industries—including those providing design services—employ many civil engineers, employ­ ment opportunities will vary by geographic area and may decrease during economic slowdowns, when construction often is curtailed.

Electrical and Electronics Engineers (D.O.T. 003.061, .167 except -034 and -070, and .187)  Nature of the Work Electrical and electronics engineers design, develop, test, and super­ vise the manufacture of electrical and electronic equipment. Electri­ cal equipment includes power generating and transmission equip­ ment used by electric utilities, and electric motors, machinery controls, and lighting and wiring in buildings, automobiles, and air­ craft. Electronic equipment includes radar, computer hardware, and communications and video equipment. The specialties of electrical and electronics engineers include sev­ eral major areas—such as power generation, transmission, and dis­ tribution; communications; computer electronics; and electrical equipment manufacturing—or a subdivision of these areas—indus­ trial robot control systems or aviation electronics, for example. Electrical and electronics engineers design new products, write per­ formance requirements, and develop maintenance schedules. They also test equipment, solve operating problems, and estimate the time and cost of engineering projects. Employment Electrical and electronics engineers held about 370,000jobs in 1992, making it the largest branch of engineering. Most jobs were in firms that manufacture electrical and electronic equipment, business ma­ chines, professional and scientific equipment, and aircraft and air­ craft parts. Computer and data processing services firms, engineer­ ing and business consulting firms, public utilities, and government agencies accounted for most of the remaining jobs. Job Outlook Employment opportunities for electrical and electronics engineers are expected to be good through the year 2005. Most job openings 8 Federal Reserve Bank of St. Louis  will result from job growth and the need to replace electrical engi­ neers who transfer to other occupations or leave the labor force. These openings should be sufficient to absorb the number of new graduates and other entrants. Employment in this engineering specialty is expected to increase about as fast as the average for all occupations. Job growth is ex­ pected to be fastest in industrial sectors other than manufacturing. Increased demand by businesses and government for computers and communications equipment is expected to account for much of the projected employment growth. Consumer demand for electrical and electronic goods and increased research and development on com­ puters, robots, and other types of automation should create addi­ tional jobs. Because many electrical engineering jobs are defense related, cut­ backs in defense spending could result in layoffs of electrical engi­ neers, especially if a defense-related project or contract is unexpect­ edly cancelled. Furthermore, engineers who fail to keep up with the rapid changes in technology in most specialties risk technological obsolescence, which makes them more susceptible to layoffs or, at a minimum, likely to be passed over for advancement.

Industrial Engineers (D.O.T. 005.167-026; 012.061 -018, .067, .167 except -022, -026, -034, -058, and -062, and .187)  Nature of the Work Industrial engineers determine the most effective ways for an organ­ ization to use the basic factors of production—people, machines, materials, information, and energy—to make or process a product. They are the bridge between management and operations. They are  more concerned with increasing productivity through the manage­ ment of people and methods of business organization than are engi­ neers in other specialties, who generally work more with products or processes. To solve organizational, production, and related problems most efficiently, industrial engineers carefully study the product and its requirements, design manufacturing and information systems, and use mathematical analysis methods such as operations research to meet those requirements. They develop management control sys­ tems to aid in financial planning and cost analysis, design produc­ tion planning and control systems to coordinate activities and con­ trol product quality, and design or improve systems for the physical distribution of goods and services. Industrial engineers conduct surveys to find plant locations with the best combination of raw materials, transportation, and costs. They also develop wage and salary administration systems and job evaluation programs. Many industrial engineers move into management positions because the work is closely related. Employment Industrial engineers held about 119,000 jobs in 1992; about 80 per­ cent of jobs were in manufacturing industries. Because their skills can be used in almost any type of organization, industrial engineers are more widely distributed among manufacturing industries than other engineers. Their skills can be readily applied outside manufacturing as well. For example, some work for insurance companies, banks, hospitals, and retail organizations. Others work for government agencies or are independent consultants. Job Outlook Employment of industrial engineers is expected to grow about as fast as the average for all occupations through the year 2005, mak­ ing for favorable opportunities. Most job openings, however, will re­ sult from the need to replace industrial engineers who transfer to other occupations or leave the labor force. Industrial growth, more complex business operations, and the greater use of automation in factories and in offices underlie the pro­ jected employment growth. Because the main function of an indus­ trial engineer is to make a higher quality product as efficiently as possible, their services should be in demand in the manufacturing  sector as firms seek to reduce costs and increase productivity through scientific management and safety engineering.

Mechanical Engineers (D.O.T. 007.061, .161-022, -034, and -038, and .267-010)  Nature of the Work Mechanical engineers plan and design tools, engines, machines, and other mechanical equipment. They design and develop power-pro­ ducing machines such as internal combustion engines, steam and gas turbines, and jet and rocket engines. They also design and de­ velop power-using machines such as refrigeration and air-condition­ ing equipment, robots, machine tools, materials handling systems, and industrial production equipment. The work of mechanical engineers varies by industry and func­ tion. Specialties include, among others, applied mechanics, design engineering, heat transfer, power plant engineering, pressure vessels and piping, and underwater technology. Mechanical engineers de­ sign tools needed by other engineers for their work. Mechanical engineering is the broadest engineering discipline, ex­ tending across many interdependent specialties. Some mechanical engineers work in production operations, maintenance, and techni­ cal sales. Many are administrators or managers. Employment Mechanical engineers held about 227,000 jobs in 1992. More than 3 out of 5 jobs were in manufacturing—of these, most were in the ma­ chinery, transportation equipment, electrical equipment, instru­ ments, and fabricated metal products industries. Business and engi­ neering consulting services and government agencies provided most of the remaining jobs. Job Outlook Employment of mechanical engineers is expected to grow about as fast as the average for all occupations through the year 2005. Al­ though overall employment in manufacturing is expected to decline, employment of mechanical engineers in manufacturing should in­ crease as the demand for machinery and machine tools grows and  V/  Industrial engineers determine the most productive way the resources of a business can be used in the production of a product.

Employment of mechanical engineers in other sectors of the econ­ omy, such as construction and services, is expected to grow faster than average as firms in these industries learn to apply these engi­ neers’ skills. Job prospects in this field should be favorable through the year 2005. Most of the expected job openings resulting from employment growth and the need to replace those who will leave the occupation should be sufficient to absorb the supply of new graduates and other entrants. Many mechanical engineering jobs are in defense related indus­ tries. Reductions in defense spending has and may continue to result in layoffs in these industries.

Metallurgical, Ceramic, and Materials Engineers (D.O.T. 006.061; 011.061; and 019.061-014)  Nature of the Work Metallurgical, ceramic, and materials engineers develop new types of metal alloys, ceramics, composites, and other materials which meet special requirements. Examples are graphite golf club shafts that are light but stiff, ceramic tiles on the space shuttle that protect it from overheating during reentry, and the alloy turbine blades in a jet. Most metallurgical engineers work in one of the three main branches of metallurgy—extractive or chemical, physical, and mechanical or process. Extractive metallurgists are concerned with removing metals from ores and refining and alloying them to obtain useful metal. Physical metallurgists study the nature, structure, and physical properties of metals and their alloys, and methods of processing metals into final products. Mechanical metallurgists de­ velop and improve metalworking processes such as casting, forging, rolling, and drawing. Ceramic engineers develop new ceramic materials and methods for making ceramic materials into useful products. Ceramics in­ clude all nonmetallic, inorganic materials which require high tem­ peratures in their processing. Ceramic engineers work on products as diverse as glassware, semiconductors, automobile and aircraft en­ gine components, fiber-optic phone lines, tile, and electric power line insulators. Materials engineers evaluate technical requirements and material specifications to develop materials that can be used, for example, to reduce the weight, but not the strength of an object. Materials engi­ neers also test and evaluate materials and develop new materials, such as the composite materials now being used in “stealth” air­ craft. Employment Metallurgical, ceramic, and materials engineers held nearly 19,000 jobs in 1992. About one-quarter worked in metal-producing and processing industries. They also worked in industries that manufac­ ture aircraft and aircraft parts, machinery, and electrical equip­ ment, and in engineering consulting firms, research and testing ser­ vices, and government agencies. Job Outlook Employment of metallurgical, ceramic, and materials engineers is expected to increase faster than the average for all occupations through the year 2005. Many of the industries in which they are 10 Federal Reserve Bank of St. Louis  A materials engineer prepares a thin-film deposition experiment. concentrated, such as stone, clay, and glass products, primary met­ als, fabricated metal products, and transportation equipment indus­ tries, are expected to experience little if any employment growth through the year 2005. Anticipated employment growth in service industries such as research and testing services and engineering and architectural services, however, should provide significant job open­ ings as these firms are employed to develop improved materials for their industrial customers. Those seeking to become employed as metallurgical, ceramic, and materials engineers should find good opportunities, as the antici­ pated growth should be sufficient to absorb the relatively low num­ ber of new graduates in this engineering discipline.

Mining Engineers (D.O.T. 010.061 except -018)  Nature of the Work Mining engineers find, extract, and prepare metals and minerals for manufacturing industries to use. They design open pit and under­ ground mines, supervise the construction of mine shafts and tunnels in underground operations, and devise methods for transporting minerals to processing plants. Mining engineers are responsible for the safe, economical, and environmentally sound operation of mines. Some mining engineers work with geologists and metallurgi­ cal engineers to locate and appraise new ore deposits. Others de­ velop new mining equipment or direct mineral processing opera­ tions to separate minerals from the dirt, rock, and other materials they are mixed with. Mining engineers frequently specialize in the mining of one mineral, such as coal or gold. With increased emphasis on protecting the environment, many mining engineers have been working to solve problems related to land reclamation and water and air pollution. Employment Mining engineers held about 3,600 jobs in 1992. Over two-thirds worked in the mining industry. Other jobs were located in engineer­ ing consulting firms, government agencies, or in manufacturing in­ dustries.  Ed___  A mining engineer studies a map of a strip mine. Mining engineers are usually employed at the location of mineral deposits, often near small communities. Those in research and de­ velopment, management, consulting, or sales, however, often are lo­ cated in metropolitan areas. Job Outlook Opportunities in the mining industry are closely related to the price of the metals and minerals they produce. If the price of these prod­ ucts is high, it makes it worthwhile for a mining company to invest the many millions of dollars in material moving equipment and ore processing technology necessary to operate the mine and make a profit. In the mid-1980’s, mining engineers experienced poor employ­ ment opportunities because low prices for oil and metals reduced profitability in coal, metal, and other mining. The prices of these commodities, metals in particular, have increased recently to levels high enough to raise output and expand employment opportunities. Although the long-term business environment for mining generally is perceived to be favorable, a mine takes years of research, plan­ ning, and development to become fully operational, and, even then, may not contribute to rapid expansion in employment opportunities for mining engineers. In fact, little change in employment is ex­ pected through the year 2005. However, the number of annual open­ ings arising from the need to replace those who transfer out of the occupation or retire should be sufficient to absorb the expected small number of new graduates and other entrants.

Nuclear Engineers  A nuclear engineer assesses the operation of a reactor and its power generating unit. Employment Nuclear engineers held about 17,000 jobs in 1992; one-fifth each were in the Federal Government, research and testing services, and utilities. Nearly half of all federally employed nuclear engineers were civilian employees of the Navy, about one-third worked for the Nuclear Regulatory Commission, and most of the rest worked for the Department of Energy or the Tennessee Valley Authority. Most nonfederally employed nuclear engineers worked for public utilities or engineering consulting companies. Some worked for defense manufacturers or manufacturers of nuclear power equipment. Job Outlook Because of concerns over the cost and safety of nuclear power, it is unlikely that any new nuclear power plants will be built by the year 2005. Nevertheless, nuclear engineers will be needed to operate ex­ isting plants. In addition, nuclear engineers will be needed to work in defense-related areas and to improve and enforce safety stan­ dards. Therefore, employment of nuclear engineers is expected to change little through the year 2005. Despite the expected absence of employment growth, good op­ portunities for nuclear engineers should exist because the number of persons graduating with degrees in nuclear engineering is likely to be in rough balance with the number of job openings. Those open­ ings will arise as nuclear engineers transfer to other occupations or leave the labor force.

They design, develop, monitor, and operate nuclear power plants used to generate electricity and power Navy ships. For exam­ ple, they may work on the nuclear fuel cycle—the production, han­ dling, and use of nuclear fuel and the safe disposal of waste pro­ duced by nuclear energy—or on fusion energy. Some specialize in the development of nuclear weapons; others develop industrial and medical uses for radioactive materials such as equipment to help di­ agnose and treat medical problems. Federal Reserve Bank of St. Louis  Nature of the Work Petroleum engineers explore for and produce oil and natural gas. If a workable reservoir containing oil or natural gas is discovered, pe­ troleum engineers work to achieve the maximum profitable recov­ ery from the reservoir by determining and developing the most effi­ cient production methods. Beacause only a small proportion of the oil and gas in a reservoir will flow out under natural forces, petroleum engineers develop and use various enhanced recovery methods. These include injecting 11  (See introductory part of this section for information on training requirements and earnings.)

Since even the best methods in use today recover only a portion of the oil and gas in a reservoir, petroleum engineers work to find ways to increase this proportion. Employment Petroleum engineers held over 14,000jobs in 1992, mostly in the pe­ troleum industry and closely allied fields. Employers include major oil companies and hundreds of smaller, independent oil exploration, production, and service companies. Engineering consulting firms, government agencies, oil field services, and equipment suppliers also employ petroleum engineers. Others work as independent consul­ tants. Because petroleum engineers specialize in the discovery and pro­ duction of oil and gas, relatively few are employed in the refining, transportation, and retail sectors of the oil and gas industry. Most petroleum engineers work where oil and gas are found. Large numbers are employed in Texas, Oklahoma, Louisiana, and California, including offshore sites. Also, many American petro­ leum engineers work overseas in oil-producing countries. Job Outlook The price of oil has a major effect on the level of employment oppor­ tunities for petroleum engineers in the United States. A high price of oil and gas makes it profitable for oil exploration firms to seek oil and gas reservoirs, and they will hire petroleum engineers to do so. With low oil prices, however, it is cheaper to purchase needed oil from the Organization of Petroleum Exporting Countries (OPEC), such as Saudi Arabia, who have vast oil reserves. Employment of petroleum engineers is expected to decline through the year 2005 unless oil and gas prices unexpectedly in­ crease enough to encourage increased exploration for oil in this country. Even if new job growth doesn’t materialize, employment opportunities for petroleum engineers should be good because the number of degrees granted in petroleum engineering has tradition­ ally been low. So, new graduates are not likely to significantly ex­ ceed the number of job openings that will arise as petroleum engi­ neers transfer to other occupations or leave the labor force.

Agricultural scientists study farm crops and animals and develop ways of im­ proving their quantity and quality. They look for ways to improve crop yield and quality with less labor, control pests and weeds more safely and effectively, and conserve soil and water. They research methods of converting raw agricultural commodities into attractive and healthy food products for consumers. Agricultural science is closely related to biological science, and agricultural scientists use the principles of biology, chemistry, and other sciences to solve problems in agriculture. They often work with biological scientists on basic biological research and in apply­ ing to agriculture the advances in knowledge brought about by bio­ technology. Many agricultural scientists manage or administer research and development programs or manage marketing or production opera­ tions in companies that produce food products or agricultural chemicals, supplies, and machinery. Many work in basic or applied research and development. Some agricultural scientists are consul­ tants to business firms, private clients, or to government. Depending on the agricultural scientist’s area of specialization, the nature of the work performed varies. Food science. Food scientists or technologists are usually employed in the food processing industry, universities, or the Federal Govern­ ment, and help meet consumer demand for food products that are healthful, safe, palatable, and convenient. To do this, they use their knowledge of chemistry, microbiology, and other sciences to de­ velop new or better ways of preserving, processing, packaging, stor­ ing, and delivering foods. Some engage in basic research, discover­ ing new food sources; analyzing food content to determine levels of vitamins, fat, sugar, or protein; or searching for substitutes for harmful or undesirable additives, such as nitrites. Many food tech­ nologists work in product development. Others enforce government regulations, inspecting food processing areas and ensuring that sani­ tation, safety, quality, and waste management standards are met. Plant science. Another important area of agricultural science is plant science, which includes the disciplines of agronomy, crop sci­ ence, entomology, and plant breeding, among others. These scien­ tists study plants and their growth in soils, helping producers of food, feed, and fiber crops to continue to feed a growing population while conserving natural resources and maintaining the environ­ ment. Agronomists and crop scientists not only help increase pro­ ductivity, but also study ways to improve the nutritional value of crops and the quality of seed. Some crop scientists study the breed­ ing, physiology, and management of crops and use genetic engineer­ ing to develop crops resistant to pests and drought. Soil science. Soil scientists study the chemical, physical, biological, and mineralogical composition of soils as they relate to plant or crop growth. They study the responses of various soil types to fertilizers, tillage practices, and crop rotation. Many soil scientists who work for the Federal Government conduct soil surveys, classifying and mapping soils. They provide information and recommendations to farmers and other landowners regarding the best use of land and how to avoid or correct problems such as erosion. They may also consult with engineers and other technical personnel working on construction projects about the effects of, and solutions to, soil  problems. Since soil science is closely related to environmental sci­ ence, persons trained in soil science also apply their knowledge to ensure environmental quality and effective land use.  pharmaceutical companies, wholesale distributors, and food prod­ ucts companies. About 5,000 agricultural scientists were self-em­ ployed in 1992, mainly as consultants.  Animal science. Animal scientists develop better, more efficient ways of producing and processing meat, poultry, eggs, and milk. Dairy scientists, poultry scientists, animal breeders, and other re­ lated scientists study the genetics, nutrition, reproduction, growth, and development of domestic farm animals. Some animal scientists inspect and grade livestock food products, purchase livestock, or work in technical sales or marketing. As extension agents or consul­ tants, animal scientists advise agricultural producers on how to up­ grade animal housing facilities properly, lower mortality rates, or increase production of animal products, such as milk or eggs.  Training, Other Qualifications, and Advancement Training requirements for agricultural scientists depend on spe­ cialty and the type of work they perform. A bachelor’s degree in ag­ ricultural science is sufficient for some jobs in applied research or in assisting in basic research, but a master’s or doctoral degree is re­ quired for basic research. A Ph.D. degree in agricultural science is usually needed for college teaching and for advancement to admin­ istrative research positions. Degrees in related sciences such as biol­ ogy, chemistry, or physics or in related engineering specialties also may qualify persons for some agricultural science jobs. All States have at least one land-grant college which offers agri­ cultural science degrees. Many other colleges and universities also offer agricultural science degrees or some agricultural science courses. However, not every school offers all specialties. A typical undergraduate agricultural science curriculum includes communi­ cations, economics, business, and physical and life sciences courses, in addition to a wide variety of technical agricultural science courses. For prospective animal scientists, these technical agricul­ tural science courses might include animal breeding, reproductive physiology, nutrition, and meats and muscle biology; students pre­ paring as food scientists take courses such as food chemistry, food analysis, food microbiology, and food processing operations; and those preparing as crop or soil scientists take courses in plant pa­ thology, soil chemistry, entomology, plant physiology, and bio­ chemistry, among others. Advanced degree programs include class­ room and fieldwork, laboratory research, and a thesis based on independent research. Agricultural scientists should be able to work independently or as part of a team and be able to communicate clearly and concisely, both orally and in writing. Most agricultural scientists also need an understanding of basic business principles. Agricultural scientists who have advanced degrees usually begin in research or teaching. With experience, they may advance to jobs such as supervisors of research programs or managers of other agri­ culture-related activities.  Working Conditions Agricultural scientists involved in management or basic research tend to work regular hours in offices and laboratories. The working environment for those engaged in applied research or product devel­ opment varies, depending on the discipline of agricultural science and the type of employer. For example, food scientists in private in­ dustry may work in test kitchens while investigating new processing techniques. Animal scientists working for Federal or State research stations may spend part of their time at dairies, farrowing houses, feedlots, farm animal facilities, or outdoors conducting research as­ sociated with livestock. Soil and crop scientists also spend time out­ doors conducting research on farms or agricultural research sta­ tions. Employment Agricultural scientists held about 29,000 jobs in 1992. In addition, several thousand persons held agricultural science faculty positions in colleges and universities. (See the statement on college and uni­ versity faculty elsewhere in the Handbook.) About two-fifths of all nonfaculty agricultural scientists work for Federal, State, or local governments. Nearly 3 out of 10 worked for the Federal Government in 1992, mostly in the Department of Agri­ culture. In addition, large numbers worked for State governments at State agricultural colleges or agricultural research stations. Some worked for agricultural service companies; others worked for com­ mercial research and development laboratories, seed companies,  >1  Agricultural scientists who specialize in agronomy work to improve crop yield and quality. Federal Reserve Bank of St. Louis  Job Outlook Employment of agricultural scientists is expected to grow about as fast as the average for all occupations through the year 2005. Addi­ tionally, the need to replace agricultural scientists who retire or oth­ erwise leave the occupation permanently will account for even more job openings than projected growth. Although enrollments in agri­ cultural science programs have begun to increase again after declin­ ing for several years during the 1980’s, opportunities should still be available in most major subfields of agricultural science. Animal and plant scientists with a background in molecular biology, microbiology, genetics, or biotechnology, soil scientists with an in­ terest in the environment, and food technologists may find the best opportunities. Generally speaking, those with advanced degrees will be in the best position to enter jobs as agricultural scientists. However, com­ petition for teaching positions in colleges or universities and for some basic research jobs may be keen, even for doctoral holders. Federal and State budget cuts may limit funding for these positions through the year 2005. It is possible for bachelor’s degree holders to work in some ap­ plied research and product development positions, but usually only in certain subfields, such as food science and technology. Also, the Federal Government hires bachelor’s degree holders to work as soil scientists in the Soil Conservation Service. Despite the more limited opportunities for those with only a bachelor’s degree to obtain jobs as agricultural scientists, a bachelor’s degree in agricultural science is useful for managerial jobs in businesses that deal with ranchers and farmers such as feed, fertilizer, seed, and farm equipment manu­ facturers; retailers or wholesalers; and farm credit institutions. Four-year degrees may also help persons enter occupations such as farmer or farm manager, cooperative extension service agent, agri­ cultural products inspector, technician, landscape architect, or 13  purchasing or sales agent for agricultural commodities or farm sup­ plies. Earnings According to the College Placement Council, beginning salary of­ fers in 1992 for graduates with a bachelor’s degree in animal science averaged $20,189 a year, and for graduates in plant science, $22,150. Average Federal salaries for employees in nonsupervisory, super­ visory, and managerial positions in certain agricultural science spe­ cialties in 1993 were as follows: Animal science, $55,631; agronomy, $45,911; soil science, $43,033; horticulture, $44,492; entomology, $53,889. Related Occupations The work of agricultural scientists is closely related to that of biolo­ gists and other natural scientists such as chemists and physicists. It is also related to agricultural production occupations such as farmer and farm manager and cooperative extension service agent as well as to the work of foresters and conservation scientists. Certain special­ ties of agricultural science are also related to other occupations. For example, the work of animal scientists is related to that of veterinari­ ans; horticulturists, to landscape architects; and soil scientists, to soil conservationists.

Most specialize in some area of biology such as zoology (the study of animals) or microbiology (the study of microscopic organisms). Many biological scientists and virtually all medical scientists work in research and development. Some conduct basic research to increase knowledge of living organisms. Others, in applied research, use knowledge provided by basic research to develop new medicines, increase crop yields, and improve the environment. Bio­ logical and medical scientists who conduct research usually work in laboratories and use electron microscopes, computers, thermal cy­ clers, or a wide variety of other equipment. Some may conduct ex­ periments on laboratory animals or greenhouse plants. For some kinds of biological scientists, a good deal of research is performed outside of laboratories. For example, a botanist may do research in 14 Federal Reserve Bank of St. Louis  tropical rain forests to see what plants grow there, or an ecologist may study how a forest area recovers after a fire. Some biological and medical scientists work in management or administration. They may plan and administer programs for testing foods and drugs, for example, or direct activities at zoos or botanical gardens. Some biological scientists work as consultants to business firms or to government, while others test and inspect foods, drugs, and other products or write for technical publications. Some work in sales and service jobs for companies manufacturing chemicals or other technical products. (See the statement on manufacturers’ and wholesale sales representatives elsewhere in the Handbook.) In recent years, advances in basic biological knowledge, especially at the genetic level, have spurred the field of biotechnology. Biologi­ cal and medical scientists using this technology manipulate the ge­ netic material of animals or plants, attempting to make organisms more productive or disease resistant. The first application of this technology has been in the medical and pharmaceutical areas. Many substances not previously available in large quantities are starting to be produced by biotechnological means; some may be useful in treating cancer and other diseases. Advances in biotechnology have opened up research opportunities in almost all areas of biology, in­ cluding commercial applications in agriculture and the food and chemical industries. Most biological scientists who come under the broad category of biologist are further classified by the type of organism they study or by the specific activity they perform, although recent advances in the understanding of basic life processes at the molecular and cellu­ lar level have blurred some traditional classifications. Aquatic biologists study plants and animals living in water. Marine biologists study salt water organisms and limnologists study fresh water organisms. Marine biologists are sometimes called oceanographers, but oceanography usually refers to the study of the physical characteristics of oceans and the ocean floor. (See the state­ ment on geologists and geophysicists elsewhere in the Handbook.) Biochemists study the chemical composition of living things. They try to understand the complex chemical combinations and re­ actions involved in metabolism, reproduction, growth, and heredity. Much of the work in biotechnology is done by biochemists and mo­ lecular biologists because this technology involves understanding the complex chemistry of life. Botanists study plants and their environment. Some study all as­ pects of plant life; others specialize in areas such as identification and classification of plants, the structure and function of plant parts, the biochemistry of plant processes, or the causes and cures of plant diseases. Microbiologists investigate the growth and characteristics of mi­ croscopic organisms such as bacteria, algae, or fungi. Medical mi­ crobiologists study the relationship between organisms and disease or the effect of antibiotics on microorganisms. Other microbiolo­ gists may specialize in environmental, food, agricultural, or indus­ trial microbiology, virology (the study of viruses), or immunology (the study of mechanisms that fight infections). Many microbiolo­ gists are using biotechnology to advance knowledge of cell repro­ duction and human disease. Physiologists study life functions of plants and animals, both in the whole organism and at the cellular or molecular level, under normal and abnormal conditions. Physiologists may specialize in functions such as growth, reproduction, photosynthesis, respiration, or movement, or in the physiology of a certain area or system of the organism. Zoologists study animals—their origin, behavior, diseases, and life processes. Some experiment with live animals in controlled or natu­ ral surroundings while others dissect dead animals to study their structure. Zoologists are usually identified by the animal group studied—ornithologists (birds), mammalogists (mammals), herpe­ tologists (reptiles), and ichthyologists (fish). Ecologists study the relationship among organisms and between organisms and their environments and the effects of influences such as population size, pollutants, rainfall, temperature, and altitude. Agricultural scientists, who may also be classified as biological scientists, are included in a separate statement elsewhere in the Handbook.  Biological scientists who do biomedical research are usually called medical scientists. Medical scientists working on basic re­ search into normal biological systems often do so in order to under­ stand the causes of and to discover treatment for disease and other health problems. Medical scientists may try to identify the kinds of changes in a cell, chromosome, or even gene that signal the develop­ ment of medical problems, such as different types of cancer. After identifying structures of or changes in organisms that provide clues to health problems, medical scientists may then work on the treat­ ment of problems. For example, a medical scientist involved in can­ cer research might try to formulate a combination of drugs which will lessen the effects of the disease. Medical scientists who have a medical degree might then administer the drugs to patients in clinical trials, monitor their reactions, and observe the results. (Medical scientists who do not have a medical degree normally col­ laborate with a medical doctor who deals directly with patients.) The medical scientist might then return to the laboratory to ex­ amine the results and, if necessary, adjust the dosage levels to reduce negative side effects or to try to induce even better results. In addi­ tion to using basic research to develop treatments for health problems, medical scientists attempt to discover ways to prevent health problems from developing, such as affirming the link be­ tween smoking and increased risk of lung cancer, or alcoholism and liver disease. Working Conditions Biological and medical scientists generally work regular hours in of­ fices or laboratories and usually are not exposed to unsafe or un­ healthy conditions. Some work with dangerous organisms or toxic substances in the laboratory, so strict safety procedures must be fol­ lowed to avoid contamination. Medical scientists also spend time working in clinics and hospitals administering drugs and treatments to patients in clinical trials. Many biological scientists such as bota­ nists, ecologists, and zoologists take field trips which involve strenu­ ous physical activity and primitive living conditions. Employment Biological and medical scientists held about 117,000jobs in 1992. In addition, many biological and medical scientists held biology faculty positions in colleges and universities. (See the statement on college and university faculty elsewhere in the Handbook.)  —fin  'm  &  Research biological scientists use a variety ofsophisticated laboratory equipment, such as scanning electron microscopes. Federal Reserve Bank of St. Louis  Almost 4 in 10 nonfaculty biological scientists were employed by Federal, State, and local governments. Federal biological scientists worked mainly in the U.S. Departments of Agriculture, the Interior, and Defense, and in the National Institutes of Health. Most of the rest worked in the pharmaceutical industry, hospitals, or research and testing laboratories. About one-fifth of medical scientists worked in research and testing laboratories, with most of the re­ mainder found in hospitals and the pharmaceutical industry. Training, Other Qualifications, and Advancement For biological scientists, the Ph.D. degree generally is required for college teaching, independent research, and for advancement to ad­ ministrative positions. A master’s degree is sufficient for some jobs in applied research and for jobs in management, inspection, sales, and service. The bachelor’s degree is adequate for some nonresearch jobs. Some graduates with a bachelor’s degree start as biological scientists in testing and inspection, or get jobs related to biological science such as technical sales or service representatives. In some cases, graduates with a bachelor’s degree are able to work in a labo­ ratory environment on their own projects, but this is unusual. Some may work as research assistants. Others become biological techni­ cians, medical laboratory technologists or, with courses in educa­ tion, high school biology teachers. (See the statements on clinical laboratory technologists and technicians; science technicians; and kindergarten, elementary, and secondary school teachers elsewhere in the Handbook.) Many with a bachelor’s degree in biology enter medical, dental, veterinary, or other health profession schools. Some enter a wide range of occupations with little or no connection to biology. Most colleges and universities offer bachelor’s degrees in biologi­ cal science and many offer advanced degrees. Curriculums for ad­ vanced degrees often emphasize a subfield such as microbiology or botany but not all universities offer all curriculums. Advanced de­ gree programs include classroom and field work, laboratory re­ search, and a thesis or dissertation. Biological scientists who have advanced degrees usually begin in research or teaching. With expe­ rience, they may become managers or administrators within biol­ ogy; others leave biology for nontechnical managerial, administra­ tive, and sales jobs. Biological scientists should be able to work independently or as part of a team and be able to communicate clearly and concisely, both orally and in writing. Those doing field research in remote ar­ eas must have physical stamina. The Ph.D. degree in a biological science is the minimum educa­ tion required for prospective medical scientists because the work of medical scientists is almost entirely research oriented. A Ph.D. de­ gree qualifies one to do research on basic life processes or on partic­ ular medical problems or diseases, and to analyze and interpret the results of experiments on patients. Medical scientists who adminis­ ter drug or gene therapy to human patients, or who otherwise inter­ act medically with patients (such as drawing blood, excising tissue, or performing other invasive procedures) must have a medical de­ gree. It is particularly helpful for medical scientists to earn both Ph.D. and medical degrees. In addition to the formal education, medical scientists are usually expected to spend several years in a post-doctoral position before they are offered permanent jobs. Post-doctoral work provides valua­ ble laboratory experience, including experience in specific processes and techniques (such as gene splicing) which are transferable to other research projects later on. In some institutions, the post-doc­ toral position can lead to a permanent position. Job Outlook Employment of biological and medical scientists is expected to in­ crease faster than the average for all occupations through the year 2005. Biological and medical scientists will continue to conduct ge­ netic and biotechnological research and help develop and produce products developed by new biological methods. In addition, efforts to clean up and preserve the environment will continue to add to growth. More biological scientists will be needed to determine the environmental impact of industry and government actions and to 15  correct past environmental problems. Expected expansion in re­ search related to health issues, such as AIDS, cancer, and the Human Genome project, should also result in growth. However, much research and development, including many areas of medical research, is funded by the Federal Government. Anticipated budget tightening should lead to slower employment growth of biological and medical scientists in the public sector and in some private indus­ try research laboratories as the number and amount of government grants increases more slowly than in the past. Many persons with a bachelor’s degree in biological science find jobs as science or engineering technicians or health technologists and technicians. Some become high school biology teachers, where they are usually regarded as teachers rather than biologists. Those with a doctorate in biological science may become college and uni­ versity faculty. (See statements on science and engineering techni­ cians, health technologists and technicians, high school teachers, and college and university faculty elsewhere in the Handbook.) Biological and medical scientists are less likely to lose their jobs during recessions than those in many other occupations since most are employed on long-term research projects or in agricultural re­ search. However, a recession could influence the amount of money allocated to new research and development efforts, particularly in areas of risky or innovative research. A recession could also limit the possibility of extension or renewal of existing projects. Earnings Median annual earnings for biological and life scientists were about $34,500 in 1992; the middle 50 percent earned between $26,000 and $46,800. Ten percent earned less than $20,400, and 10 percent earned over $56,900. For medical scientists, median annual earnings were about $32,400; the middle 50 percent earned between $25,800 and $52,200. Ten percent earned less than $20,000, and 10 percent earned over $77,600. According to the College Placement Council, beginning salary offers in private industry in 1992 averaged $21,850 a year for bachelor’s degree recipients in biological science. In the Federal Government in 1993, general biological scientists in nonsupervisory, supervisory, and managerial positions earned an average salary of $45,155; microbiologists averaged $49,440; ecolo­ gists, $44,657; physiologists, $55,326; and geneticists, $55,709. Related Occupations Many other occupations deal with living organisms and require a level of training similar to that of biological and medical scientists. These include the conservation occupations of forester, range man­ ager, and soil conservationist; animal breeders, horticulturists, soil scientists, and most other agricultural scientists; and life science technicians. Many health occupations are also related to those in the biological sciences, such as medical doctors, dentists, and veterinari­ ans.

Foresters and conservation scientists manage, develop, use, and help protect these and other natural resources. Foresters manage timberland, which involves a variety of duties. Those working in private industry may procure timber from private landowners. To do this, foresters contact local forest owners and gain permission to take inventory of the type, amount, and location of all standing timber on the property, a process known as timber cruising. Foresters then appraise the timber’s worth, negotiate the purchase of timber, and draw up a contract for procurement. Next, they subcontract with loggers or pulpwood cutters for tree removal, aid in road layout, and maintain close contact with the subcontrac­ tor’s workers and the landowner to ensure that the work is per­ formed to the landowner’s, as well as federal, state, and local envi­ ronmental specifications. Forestry consultants often act as agents for the forest owner, performing the above duties and negotiating timber sales with industrial procurement foresters. Throughout the process, foresters consider the economics of the purchase as well as the environmental impact on natural resources, a function which has taken on added importance in recent years. To do this, they determine how best to preserve wildlife habitats, creek beds, water quality, and soil stability and how best to comply with environmental regulations. Foresters must balance the desire to conserve forested ecosystems for future generations with the need to use forest resources for recreational or economic purposes. Foresters also supervise the planting and growing of new trees, a process called regeneration. They choose and prepare the site, using controlled burning, bulldozers, or herbicides to clear weeds, brush, and logging debris. They advise on the type, number, and placement of trees to be planted. Foresters then monitor the trees to ensure healthy growth and to determine the best time for harvesting. If they detect signs of disease or harmful insects, they decide on the best course of treatment to prevent contamination or infestation of healthy trees. Foresters who work for State and Federal governments manage public parks and forests and also work with private landowners to protect and manage forest land outside of the public domain. They may also design campgrounds and recreation areas. Foresters use a number of tools to perform their jobs: Clinometers measure the heights, diameter tapes measure the diameter, and in­ crement borers and bark gauges measure the growth of trees so that timber volumes can be computed and future growth estimated. Photogrammetry and remote sensing (aerial photographs taken from airplanes and satellites) are often used for mapping large forest areas and for detecting widespread trends of forest and land use. Com­ puters are used extensively, both in the office and in the field, for the storage, retrieval, and analysis of information required to manage the forest land and its resources. Range managers, also called range conservationists, range ecolo­ gists, or range scientists, manage, improve, and protect rangelands to maximize their use without damaging the environment. Rangelands cover about 1 billion acres of the United States, mostly in the west­ ern States and Alaska. They contain many natural resources, in­ cluding grass and shrubs for animal grazing, wildlife habitats, water from vast watersheds, recreation facilities, and valuable mineral and energy resources. Range managers help ranchers attain optimum livestock production by determining the number and kind of ani­ mals to graze, the grazing system to use, and the best season for grazing. At the same time, however, they maintain soil stability and vegetation for other uses such as wildlife habitats and outdoor recre­ ation. Soil conservationists provide technical assistance to farmers, ranchers, and others concerned with the conservation of soil, water, and related natural resources. They develop programs designed to  get the most productive use of land without damaging it. Soil con­ servationists do most of their work in the field. Conservationists visit areas with erosion problems, find the source of the problem, and help landowners and managers develop management practices to combat it. Foresters and conservation scientists often specialize in one area such as forest resource management, urban forestry, wood technol­ ogy, or forest economics. Working Conditions Working conditions for foresters and conservation scientists vary considerably. Although some of the work is solitary, they also deal regularly with landowners, loggers, forestry technicians and aides, farmers, ranchers, government officials, special interest groups, and the public in general. Some work regular hours in offices or labs. The work can still be physically demanding, though. Many forest­ ers and conservation scientists often work outdoors in all kinds of weather, sometimes in isolated areas. Some foresters may need to walk long distances through densely wooded land to carry out their work. Foresters and conservation scientists also may work long hours fighting fires or in other emergencies. Employment Foresters and conservation scientists held about 35,000jobs in 1992. About one-third of the salaried workers were in the Federal Gov­ ernment, primarily in the Department of Agriculture’s Forest Ser­ vice and Soil Conservation Service and in the Department of the In­ terior’s Bureau of Land Management. The Forest Service alone employed over 5,000 foresters and over 400 range conservationists in 1992. Another 25 percent worked for State governments, and 8 percent worked for local governments. The remainder worked in private industry, mainly in the forestry industry. Other significant employers included logging and lumber companies and sawmills. Some were self-employed as consultants for private landowners, State and Federal governments, and forestry-related businesses. Most soil conservationists work for the Department of Agricul­ ture’s Soil Conservation Service. Others are employed by State and local governments in their soil conservation districts. Although foresters and conservation scientists work in every State, employment is concentrated in the western and southeastern States, where many national and private forests and parks are, and where most of the lumber and pulpwood-producing forests are. Range managers work almost entirely in the western States, where most of the rangeland is located. Soil conservationists, on the other hand, are employed in almost every county in the country. Training, Other Qualifications, and Advancement A bachelor’s degree in forestry is the minimum educational require­ ment for professional careers in forestry. In the Federal Govern­ ment, a combination of experience and appropriate education can  A forester consults a map to locate a client's property. Federal Reserve Bank of St. Louis  occasionally substitute for a 4-year forestry degree, but job competi­ tion makes this difficult. Thirteen States have mandatory licensing or registration require­ ments which a forester must meet in order to acquire the title “pro­ fessional forester.”Becoming licensed or registered usually requires a 4-year degree in forestry, a minimum period of training time, and passing an exam. Foresters who wish to perform specialized research or teach should have an advanced degree, preferably a Ph.D. In 1993, about 55 colleges and universities offered bachelor’s or higher degrees in forestry; 45 of these were accredited by the Society of American Foresters. Curriculums stress science, mathematics, communications skills, and computer science, as well as technical forestry subjects. Courses in forest economics and business adminis­ tration supplement the student’s scientific and technical knowledge. Prospective foresters should also have a strong grasp on policy is­ sues and on the increasingly numerous and complex environmental regulations which affect many forestry-related activities. Many col­ leges require students to complete a field session in a camp operated by the college. All schools encourage students to take summer jobs that provide experience in forestry or conservation work. A bachelor’s degree in range management or range science is the usual minimum educational requirement for range managers; grad­ uate degrees generally are required for teaching and research posi­ tions. In 1992, 31 colleges and universities offered degrees in range management or range science or in a closely related discipline with a range management or range science option. A number of other schools offered some courses in range management or range science. Specialized range management courses combine plant, animal, and soil sciences with principles of ecology and resource management. Desirable electives include economics, forestry, hydrology, agron­ omy, wildlife, animal husbandry, computer science, and recreation. Very few colleges and universities offer degrees in soil conserva­ tion. Most soil conservationists have degrees in agronomy, general agriculture, or crop or soil science; a few have degrees in related fields such as wildlife biology, forestry, and range management. Programs of study generally include 30 semester hours in natural re­ sources or agriculture, including at least 3 hours in soil science. In addition to meeting the demands of forestry and conservation research and analysis, foresters and conservation scientists generally must enjoy working outdoors, be physically hardy, and be willing to move to where the jobs are. They must also work well with people and have good communications skills. Recent forestry and range management graduates usually work under the supervision of experienced foresters or range managers. After gaining experience, they may advance to more responsible po­ sitions. In the Federal Government, most entry level foresters work in forest resource management. An experienced Federal forester may supervise a ranger district, and may advance to regional forest supervisor or to a top administrative position. In private industry, foresters start by learning the practical and administrative aspects of the business and acquiring comprehensive technical training. They are then introduced to contract writing, timber harvesting, and deci­ sion making. Some foresters work their way up to top managerial positions within their companies. Foresters in management usually leave the fieldwork behind, spending more of their time in an office, working with teams to develop management plans and supervising others. After gaining several years of experience, many foresters be­ come consulting foresters, working alone or with one or several partners. They advise State or local governments, private landown­ ers, private industry, or other forestry consulting groups. Soil conservationists usually begin working within one county or conservation district and with experience may advance to the area, State, regional, or national level. Also, soil conservationists can transfer to related occupations such as farm or ranch management advisor or land appraiser. Job Outlook Employment of foresters and conservation scientists is expected to grow more slowly than the average for all occupations through the year 2005, partly due to budgetary constraints in the Federal Gov­ ernment, where employment is concentrated. However, an expected 17  wave of retirements in the Federal Government should create addi­ tional job openings for both foresters and range conservationists. Job opportunities for foresters outside of the Federal Government are expected to be better. Demand will continue to increase at the State and local government level in response to the emphasis on en­ vironmental protection and responsible land management. For ex­ ample, urban foresters are increasingly needed to do environmental impact studies in urban areas, and to help regional planning com­ missions make land use decisions, particularly in the Northeast and in other major population centers of the country. At the State level, more numerous and complex environmental regulations have cre­ ated demand for more foresters to deal with these issues. Also, the nationwide Stewardship Incentive Program, funded by the Federal Government, provides money to the States to encourage landowners to practice multiple-use forest management. Foresters will be needed to assist landowners in making decisions about how to man­ age their forested property. In private industry, more foresters should be needed to improve forest and logging practices and in­ crease output and profitability. Certain areas of the country offer greater job opportunities for foresters and range conservationists than others. Employment for range conservationists is concentrated in the West and Midwest, and most forestry-related employment is in the South and West. Earnings Most graduates entering the Federal Government as foresters, range managers, or soil conservationists with a bachelor’s degree started at $18,340 or $22,717 a year, in 1993, depending on academic achievement. Those with a master’s degree could start at $22,717 or $27,789. Holders of doctorates could start at $33,623 or, in research positions, at $40,298. In 1993, the average Federal salary for forest­ ers in nonsupervisory, supervisory, and managerial positions was $42,440; for soil conservationists, $39,448; and for forest products technologists, $56,559. In private industry, starting salaries for students with a bachelor’s degree were comparable to starting salaries in the Federal Govern­ ment, but starting salaries in State and local governments were gen­ erally lower. Foresters and conservation scientists who work for Federal, State, and local governments and large private firms generally re­ ceive more generous benefits—for example, pension and retirement plans, health and life insurance, and paid vacations—than those working for smaller firms. Related Occupations Foresters and conservation scientists are not the only workers who manage, develop, and protect natural resources. Other workers with similar responsibilities include agricultural scientists, agricultural engineers, biological scientists, environmental scientists, farmers, farm managers, ranchers, ranch managers, soil scientists and soil conservation technicians, and wildlife managers.

Although chemicals are often thought of as artificial or toxic substances, all physical things, whether naturally occurring or of human design, are composed of chemicals. Chemists have devel­ oped a tremendous variety of new and improved synthetic fibers, paints, adhesives, drugs, electronic components, lubricants, and other products. They also develop processes which save energy and reduce pollution, such as improved oil refining and petrochemical processing methods. Research on the chemistry of living things spurs advances in medicine, agriculture, food processing, and other areas. Many chemists work in research and development. In basic re­ search, chemists investigate the properties, composition, and struc­ ture of matter and the laws that govern the combination of elements and reactions of substances. In applied research and development, they create new products and processes or improve existing ones, often using knowledge gained from basic research. For example, synthetic rubber and plastics resulted from research on small mole­ cules uniting to form large ones (polymerization). Chemists also work in production and quality control in chemical manufacturing plants. They prepare instructions for plant workers which specify ingredients, mixing times, and temperatures for each stage in the process. They also monitor automated processes to en­ sure proper product yield, and they test samples to ensure they meet industry and government standards. Chemists also record and re­ port on test results. Others are marketing or sales representatives who sell and provide technical information on chemical products. Chemists often specialize in a subfield. Analytical chemists deter­ mine the structure, composition, and nature of substances and de­ velop analytical techniques. They also identify the presence and concentration of chemical pollutants in air, water, and soil. Organic chemists study the chemistry of the vast number of carbon com­ pounds. Many commercial products, such as drugs, plastics, and fertilizers, have been developed by organic chemists. Inorganic chemists study compounds consisting mainly of elements other than carbon, such as those in electronic components. Physical chemists study the physical characteristics of atoms and molecules and inves­ tigate how chemical reactions work. Their research may result in new and better energy sources. Biochemists, whose work encompasses both biology and chemis­ try, are included under biological scientists elsewhere in the Hand­ book. Working Conditions Chemists usually work regular hours in offices and laboratories. Re­ search chemists spend much time in laboratories, but also work in offices when they do theoretical research or plan, record, and report on their lab research. Although some laboratories are small, others are large and may incorporate prototype chemical manufacturing facilities as well as advanced equipment. Chemists may also do some of their research in a chemical plant or outdoors—while gathering samples of pollutants, for example. Some chemists are exposed to health or safety hazards when handling certain chemicals, but there is little risk if proper procedures are followed. Employment Chemists held about 92,000 jobs in 1992. The majority of chemists are employed in manufacturing firms—mostly in the chemical man­ ufacturing industry, which includes firms that produce plastics and synthetic materials, drugs, soap and cleaners, paints, industrial or­ ganic chemicals, and other miscellaneous chemical products. Chem­ ists also work for State and local governments, primarily in health and agriculture, and for Federal agencies, chiefly in the Depart­ ments of Defense, Health and Human Services, and Agriculture.  In government or industry, beginning chemists with a bachelor’s degree work in technical sales or services, quality control, or assist senior chemists in research and development laboratories. Some may work in research positions, analyzing and testing products, but these are often technicians’ positions, with limited upward mobility. Many employers prefer chemists with a Ph.D. to work in basic and applied research. A Ph.D. is also generally required for a 4-year col­ lege faculty position and for advancement to many administrative positions. Chemists who work in sales, marketing, or professional research positions often move into management eventually. Many people with a bachelor’s degree in chemistry enter other oc­ cupations in which a chemistry background is helpful, such as tech­ nical writers or sales representatives in chemical marketing. Some enter medical, dental, veterinary, or other health profession schools. Others choose from a wide range of occupations with little or no connection to chemistry. Chemistry graduates may become high school teachers. How­ ever, they usually are then regarded as science teachers rather than chemists. Others may qualify as engineers, especially if they have taken some courses in engineering.  Chemists contribute to the development of a variety ofpractical products, including pharmaceuticals, paints, and synthetic fibers and materials. Others work for research and testing services. In addition, thousands of persons held chemistry faculty positions in colleges and universities. (See the statement on college and university faculty elsewhere in the Handbook.) Chemists are employed in all parts of the country, but they are mainly concentrated in large industrial areas. Training, Other Qualifications, and Advancement A bachelor’s degree in chemistry or a related discipline is usually the minimum education necessary to work as a chemist. However, most research and college teaching jobs require a Ph.D. degree. Many colleges and universities offer a bachelor’s degree program in chemistry, about 602 of which are approved by the American Chemical Society. Approximately 325 colleges and universities also offer advanced degree programs in chemistry. Students planning careers as chemists should enjoy studying sci­ ence and mathematics, and should like working with their hands building scientific apparatus and performing experiments. Persever­ ance, curiosity, and the ability to concentrate on detail and to work independently are essential. In addition to required courses in ana­ lytical, inorganic, organic, and physical chemistry, undergraduate chemistry majors usually study biological sciences, mathematics, and physics. Computer courses are also important, as chemists in­ creasingly use computers as a tool in their everyday work. Because research and development chemists are increasingly ex­ pected to work on interdisciplinary teams, some understanding of other disciplines, including business and marketing, is desirable, along with leadership ability and good oral and written communica­ tion skills. Experience, either in academic laboratories or through internships or co-op programs in industry, also is useful. Although graduate students typically specialize in a subfield of chemistry, such as analytical chemistry or polymer chemistry, stu­ dents usually need not specialize at the undergraduate level. In fact, undergraduates who are broadly trained have more flexibility when job hunting or changing jobs than if they narrowly define their inter­ ests. Some employers provide new bachelor’s degree chemists with additional training or education. Federal Reserve Bank of St. Louis  Job Outlook Employment of chemists is expected to grow about as fast as the av­ erage for all occupations through the year 2005. The chemical in­ dustry should face continued demand for goods such as new and better pharmaceuticals and personal care products, as well as more specialty chemicals designed to address specific problems or appli­ cations. To meet these demands, research and development expend­ itures will continue to increase, contributing to employment growth for chemists. However, employment will not grow as rapidly as in the past be­ cause, overall, research and development budgets are expected to grow more slowly compared to those of the 1980’s as firms restruc­ ture and streamline their operations. Also, temporary slowdowns in automobile manufacturing and construction, end users of many of the products of the chemical industry, will have a short-term damp­ ening effect on chemists’ employment. Regardless of the outlook, hiring may slow and layoffs occur during periods of economic reces­ sion, especially in the oil and industrial chemicals industries.  Earnings According to a 1992 survey by the American Chemical Society, the median starting salary for recently graduated chemists with a bache­ lor’s degree was about $24,000 a year; with a master’s degree, $32,000; with a Ph.D., $48,000. The American Chemical Society also reports that the median sal­ ary of their members of all experience levels with a bachelor’s degree was $42,000 a year in 1992; with a master’s degree, $50,000; and with a Ph.D., $60,000. In 1993, chemists in nonsupervisory, supervisory, and managerial positions in the Federal Government earned an average salary of $51,537. Related Occupations The work of chemical engineers, agricultural scientists, biological scientists, and chemical technicians is closely related to the work done by chemists. The work of other physical and life science occu­ pations may also be similar to that of chemists.

They identify and examine rocks, study information collected by remote sensing instruments in satellites, conduct geo­ logical surveys, construct maps, and use instruments to measure the earth’s gravity and magnetic field. They also analyze information collected through seismic prospecting, which involves bouncing sound waves off buried rock layers. Many geologists and geophysi­ cists search for oil, natural gas, minerals, and underground water. Increasingly, geologists, geophysicists, and other earth scientists are becoming known as geological scientists or geoscientists, terms which better describe their role in studying all aspects of the earth. Geoscientists play an increasingly important part in studying, preserving, and cleaning up the environment. Many design and monitor waste disposal sites, preserve water supplies, and reclaim contaminated land and water to comply with stricter Federal envi­ ronmental rules. They also help locate safe sites for hazardous waste facilities and landfills. Geologists and geophysicists examine chemical and physical properties of specimens in laboratories, sometimes under controlled temperature and pressure. They may study fossil remains of animal and plant life or experiment with the flow of water and oil through rocks. Some geoscientists use two- or three-dimensional computer modeling to portray water layers and the flow of water or other fluids through rock cracks and porous materials. A large variety of sophisticated laboratory instruments is used, including x-ray dif­ fractometers, which determine the crystal structure of minerals, and petrographic microscopes, for study of rock and sediment samples. The locations and intensities of earthquakes are determined using seismographs, instruments which measure energy waves resulting from movements in the earth’s crust. Geologists and geophysicists also apply geological knowledge to engineering problems in constructing large buildings, dams, tun­ nels, and highways. Some administer and manage research and ex­ ploration programs, and others become general managers in petro­ leum and mining companies. Geology and geophysics are closely related fields, but there are some major differences. Geologists study the composition, struc­ ture, and history of the earth’s crust. They try to find out how rocks were formed and what has happened to them since their formation. Geophysicists use the principles of physics and mathematics to study not only the earth’s surface but its internal composition, ground and surface waters, atmosphere, and oceans as well as its magnetic, electrical, and gravitational forces. Both, however, com­ monly apply their skills to the search for natural resources and to solve environmental problems. Geologists and geophysicists often specialize. Geological oceanog­ raphers study and map the ocean floor. They collect information us­ ing remote sensing devices aboard surface ships or underwater re­ search craft. Physical oceanographers study the physical aspects of oceans such as currents and the interaction of the surface of the sea with the atmosphere. Chemical oceanographers study the chemical composition, dissolved elements, and nutrients of oceans. Although biological scientists who study ocean life are also called oceanogra­ phers (as well as marine biologists), the work they do and the train­ ing they need are related to biology rather than geology or geophys­ ics. (See the statement on biological scientists elsewhere in the Handbook.) Hydrologists study the distribution, circulation, and physical properties of underground and surface waters. They study the form and intensity of precipitation, its rate of infiltration into the soil, and its return to the ocean and atmosphere. Petroleum geolo­ gists explore for oil and gas by studying and mapping the subsurface of the ocean or land. They use sophisticated geophysical instrumen­ tation, well log data, and computers to collect information. Mineral­ ogists analyze and classify minerals and precious stones according to composition and structure. Paleontologists study fossils found in ge­ ological formations to trace the evolution of plant and animal life 20 Federal Reserve Bank of St. Louis  and the geologic history of the earth. Seismologists interpret data from seismographs and other geophysical instruments to detect earthquakes and locate earthquake-related faults. Stratigraphers help to locate minerals by studying the distribution and arrange­ ment of sedimentary rock layers and by examining the fossil and mineral content of such layers. Working Conditions Some geoscientists spend the majority of their time in an office, others divide their time between fieldwork and office or laboratory work. Geologists often travel to remote field sites by helicopter or four-wheel drive vehicles and cover large areas by foot. Exploration geologists and geophysicists often work overseas or in remote areas, and job relocation is not unusual. Geological and physical oceanog­ raphers may spend considerable time at sea. Employment Geologists and geophysicists held about 48,000 jobs in 1992. In ad­ dition, thousands of persons held geology, geophysics, and oceanog­ raphy faculty positions in colleges and universities. (See the state­ ment on college and university faculty elsewhere in the Handbook.) About 1 in 4 were employed in oil and gas companies or oil and gas field service firms. Many other geologists worked for consulting firms and business services, especially engineering services, which often provide services to oil and gas companies. About 1 geologist in 10 was self-employed; most of these were consultants to industry or government. The Federal Government employed about 6,400 geologists, geo­ physicists, oceanographers, and hydrologists in 1992. Over one-half worked for the Department of the Interior in the U.S. Geological Survey, the Bureau of Land Management, the Minerals Manage­ ment Service, the Bureau of Mines, and the Bureau of Reclamation. Others worked for the Departments of Defense, Agriculture, Com­ merce, and Energy, and the Environmental Protection Agency. Some worked for State agencies such as State geological surveys and State departments of conservation. Geologists and geophysicists also worked for nonprofit research institutions. Some were em­ ployed by American firms overseas for varying periods of time. Training, Other Qualifications, and Advancement A bachelor’s degree in geology or geophysics is adequate for entry into some lower level geology jobs, but better jobs with good ad­ vancement potential usually require at least a master’s degree in ge­ ology or geophysics. Persons with strong backgrounds in physics, chemistry, mathematics, or computer science also may qualify for some geophysics or geology jobs. A Ph.D. degree is essential for most college or university teaching positions, and is important for work in Federal agencies that involves basic research.  sjpti' ^SSgSfc-  Geologists and geophysicists often apply their knowledge of the physical aspects of the earth to solve or prevent environmental problems.  Over 500 colleges and universities offer a bachelor’s degree in ge­ ology, geophysics, oceanography, or other geoscience. Other pro­ grams offering related training for beginning geological scientists in­ clude geophysical technology, geophysical engineering, geophysical prospecting, engineering geology, petroleum geology, and geochem­ istry. In addition, more than 300 universities award advanced de­ grees in geology or geophysics. Geologists and geophysicists need to be able to work as part of a team. Computer modeling, data processing, and effective oral and written communication skills are important, as well as the ability to think independently and creatively. Those involved in fieldwork must have physical stamina. Traditional geoscience courses emphasizing classical geologic methods and concepts (such as mineralogy, paleontology, stra­ tigraphy, and structural geology) are important for all geoscientists. However, those students interested in working in the environmental or regulatory fields should take courses in hydrology, hazardous waste management, environmental legislation, chemistry, fluid mechanics, and geologic logging. Geologists and geophysicists often begin their careers in field ex­ ploration or as research assistants in laboratories. They are given more difficult assignments as they gain experience. Eventually they may be promoted to project leader, program manager, or other management and research positions. Job Outlook Employment of geologists and geophysicists is expected to grow about as fast as the average for all occupations through the year 2005. Many jobs for geologists and geophysicists are in or related to the petroleum industry, especially the exploration for oil and gas. This industry is subject to cyclical fluctuations. Low oil prices, higher production costs, improvements in energy efficiency, and re­ strictions on potential drilling sites have caused exploration activi­ ties to be curtailed in the United States. If these conditions continue, there will be few openings in the petroleum industry for geoscien­ tists working in the United States. As a result of generally poor job prospects in the past few years, the number of students enrolling in geology and geophysics has dropped considerably. Although enrollments are rising again, the number of students trained in petroleum geology is likely to be so low that even a small increase in openings in the oil industry will be greater than the number of petroleum geologists and geophysicists available to fill them, creating good employment opportunities if ex­ ploration activities increase. Despite the generally poor job prospects encountered by geo­ scientists in recent years in the petroleum industry, the demand for these professionals in environmental protection and reclamation has been growing rapidly. Geologists and geophysicists will be needed to help clean up contaminated sites in the United States, and to help private companies and government comply with more numerous and complex environmental regulations. In particular, jobs requir­ ing training in engineering geology, hydrology and geochemistry should be in demand. However, if the number of geo-scientists who obtain training in these areas increases very rapidly, they may expe­ rience competition despite the increasing number of jobs available. Earnings Surveys by the College Placement Council indicate that graduates with bachelor’s degrees in the geological sciences received an aver­ age starting offer of $25,704 a year in 1992. According to a 1991 American Geological Institute survey, the average starting salaries for inexperienced geoscientists were about $23,100 for those with a bachelor’s degree, $28,100 for those with a master’s degree, and $33,600 for those with a Ph.D. However, the starting salaries can vary widely depending on the employing indus­ try. For example, the oil and gas industry offered an average starting salary of $36,250 for bachelor’s degree holders, while in research in­ stitutions, colleges, and universities, new hires with a bachelor’s de­ gree averaged about $21,000. Although the petroleum, mineral, and mining industries offer higher salaries, the competition in these areas is normally intense, and the job security less than in other areas. Federal Reserve Bank of St. Louis  In 1993, the Federal Government’s average salary for geologists in managerial, supervisory, and nonsupervisory positions was $51,800; for geophysicists, $57,929; for hydrologists, $47,793; and for oceanographers, $54,552. Related Occupations Many geologists and geophysicists work in the petroleum and natu­ ral gas industry. This industry also employs many other workers in the scientific and technical aspects of petroleum and natural gas ex­ ploration and extraction, including engineering technicians, science technicians, petroleum engineers, and surveyors. Also, some life scientists, physicists, chemists, and meteorologists, as well as mathe­ maticians, computer scientists, soil scientists, and mapping scien­ tists, do related work in both petroleum and natural gas exploration and extraction and in environment-related activities.

Meteorologists (D.O.T. 025.062-010)  Nature of the Work Meteorology is the study of the atmosphere, the air that covers the earth. Meteorologists study the atmosphere’s physical characteris­ tics, motions, and processes, and the way the atmosphere affects the rest of our environment. The best-known application of this knowl­ edge is in forecasting the weather. However, weather information and meteorological research also are applied in air-pollution con­ trol, agriculture, air and sea transportation, defense, and the study of trends in the earth’s climate such as global warming or ozone de­ pletion. Meteorologists who forecast the weather, known professionally as operational meteorologists, are the largest group of specialists. They study information on air pressure, temperature, humidity, and wind velocity, and they apply physical and mathematical relationships to make short- and long-range weather forecasts. Their data come from weather satellites, weather radar, and remote sensors and ob­ servers in many parts of the world. Meteorologists use sophisticated computer models of the world’s atmosphere to help forecast the weather and interpret the results of these models to make long-term, short-term, and local-area forecasts. These forecasts inform not only the general public, but also those who need accurate weather infor­ mation for both economic and safety reasons, as in the shipping, avi­ ation, agriculture, fishing, and utilities industries. The use of weather balloons, launched twice a day, to measure wind, temperature, and humidity in the upper atmosphere, is being supplemented by more sophisticated weather equipment which transmits data as frequently as every few minutes. Doppler radar, for example, can detect rotational patterns in violent storm systems, 21  allowing forecasters to better predict thunderstorms, tornadoes, flash floods, as well as their direction and intensity. Some meteorologists engage in research. Physical meteorologists, for example, study the atmosphere’s chemical and physical proper­ ties; the transmission of light, sound, and radio waves; and the trans­ fer of energy in the atmosphere. They also study factors affecting formation of clouds, rain, snow, and other weather phenomena, such as severe storms. Climatologists collect, analyze, and interpret past records of wind, rainfall, sunshine, and temperature in specific areas or regions. Their studies are used to design buildings and to plan heating and cooling systems, effective land use, and agricul­ tural production. Other research meteorologists may examine the most effective ways to control or diminish air pollution or improve weather forecasting using mathematical models. Working Conditions Jobs in weather stations, most of which operate around the clock 7 days a week, often involve night, weekend, and holiday work and ro­ tating shifts. Operational meteorologists are often under pressure to meet forecast deadlines. Weather stations are found all over the country: At airports, in or near cities, and in isolated and remote ar­ eas. Meteorologists in smaller weather offices often work alone; in larger ones, they work as part of a team. Meteorologists not doing forecasting work regular hours, usually in offices. Employment Meteorologists held about 6,100 jobs in 1992. The largest employer of civilian meteorologists is the National Oceanic and Atmospheric Administration (NOAA), which employs about 2,400 meteorolo­ gists. The majority of NOAA’s meteorologists work in the National Weather Service at stations in all parts of the United States. The re­ mainder of NOAA’s meteorologists work mainly in research or in program management. The Department of Defense employs about 280 civilian meteorologists. Others work for private weather consul­ tants, research and testing services, and computer and data process­ ing services. Hundreds of people teach meteorology and related courses in col­ lege and university departments of meteorology or atmospheric sci­ ence, physics, earth science, and geophysics. (See the statement on college and university faculty elsewhere in the Handbook.)  II  &88D WEAT!  Meteorologists involved in weather forecasting sometimes work evenings, weekends, or holidays. 22 Federal Reserve Bank of St. Louis  In addition to civilian meteorologists, thousands of members of the Armed Forces do forecasting and other meteorological work. Training, Other Qualifications, and Advancement A bachelor’s degree with a major in meteorology or a closely related field with coursework in meteorology is the usual minimum require­ ment for a beginning job as a meteorologist. The preferred educational requirement for entry level meteorolo­ gists in the Federal Government is a bachelor’s degree—not neces­ sarily in meteorology—with at least 20 semester hours of meteorol­ ogy courses, including 6 hours in weather analysis and forecasting and 6 hours in dynamic meteorology. In addition to meteorology coursework, differential and integral calculus and 6 hours of college physics are required. These requirements will probably be upgraded soon, and most likely will include coursework in computer science and additional coursework appropriate for a physical science major, such as statistics, chemistry, physical oceanography, or physical cli­ matology. Sometimes, a combination of experience and education may be substituted for a degree. Although positions in operational meteorology are available for those with only a bachelor’s degree, obtaining a graduate degree en­ hances advancement potential. A master’s degree is usually neces­ sary for conducting research and development, and a Ph.D. is usu­ ally required for college teaching. Students who plan a career in teaching or research and development need not necessarily major in meteorology as an undergraduate. In fact, a bachelor’s degree in mathematics, physics, or engineering is excellent preparation for graduate study in meteorology. Because meteorology is a small field, relatively few colleges and universities offer degrees in meteorology or atmospheric science, al­ though many departments of physics, earth science, geography, and geophysics offer atmospheric science and related courses. Prospec­ tive students should make certain that courses required by the Na­ tional Weather Service and other employers are offered at the col­ lege they are considering. Computer science courses, additional meteorology courses, and a strong background in mathematics and physics are expected to become more important to prospective em­ ployers as new, sophisticated weather equipment and radar systems become operational. Many programs combine the study of meteor­ ology with another field, such as agriculture, engineering, or phys­ ics. For example, hydrometeorology is the blending of hydrology (the science of the earth’s water) and meteorology, and this is an emerging field concerned with the impact of precipitation on the hy­ drologic cycle and the environment. Beginning meteorologists often do routine data collection, com­ putation, or analysis and some basic forecasting. Entry level meteo­ rologists in the Federal Government are usually placed in intern po­ sitions for training and experience. Experienced meteorologists may advance to various supervisory or administrative jobs, or may han­ dle more complex forecasting jobs. Increasing numbers of meteorol­ ogists establish their own weather consulting services. Job Outlook Employment of meteorologists is expected to grow as fast as the av­ erage for all occupations through the year 2005. The National Weather Service, which employs many meteorologists, expects to increase its employment of meteorologists, mainly in its field offices, to improve short-term and local-area weather forecasts. Although some of these additional jobs are being filled internally through the upgrading of meteorological technicians, there still should be more openings in the National Weather Service in the next 5 years than there have been in the past. Employment of meteorologists in other parts of the Federal Government is not expected to increase. Addi­ tional jobs will be created in private industry with the increased use of private weather forecasting and meteorological services by farm­ ers, commodity investors, utilities, transportation and construction firms, and radio and TV stations. For people in these and other ar­ eas, even a slight improvement in the detail and accuracy of weather information and forecasts over the general information provided by the National Weather Service can yield significant benefits. How­ ever, because many customers for private weather services are in in­ dustries sensitive to fluctuations in the economy, the sales and  growth of private weather services depend on the health of the econ­ omy. Along with the projected average growth, many of the job open­ ings in this very small occupation will arise from the need to replace those who transfer to other occupations or leave the labor force. Earnings The average salary for meteorologists in nonsupervisory, supervi­ sory, and managerial positions employed by the Federal Govern­ ment was $48,266 in 1993. In 1993, meteorologists in the Federal Government with a bachelor’s degree and no experience received a starting salary of $18,340 or $22,717 a year, depending on their col­ lege grades. Those with a master’s degree could start at $22,717 or $27,790; those with the Ph.D. degree, at $33,623 or $40,299. Related Occupations Workers in other occupations concerned with the physical environ­ ment include oceanographers, geologists and geophysicists, hydrol­ ogists, and civil and environmental engineers.

Physicists and Astronomers (D.O.T. 015.021-010; 021.067-010; 023.061-010, -014, and .067; 079.021-014)  Nature of the Work Physicists explore and identify basic principles governing the struc­ ture and behavior of matter, the generation and transfer of energy, and the interaction of matter and energy. Some physicists use these principles in theoretical areas, such as the nature of time and the ori­ gin of the universe, while others work in practical areas such as the development of advanced materials, electronic and optical devices, and medical equipment. Physicists design and perform experiments with lasers, cyclo­ trons, telescopes, mass spectrometers, and other equipment. Based on observations and analysis, they attempt to discover the laws that describe the forces of nature, such as gravity, electromagnetism, and nuclear interactions. They also find ways to apply physical laws and theories to problems in nuclear energy, electronics, optics, materi­ als, communications, aerospace technology, and medical instru­ mentation. Astronomy is sometimes considered a subfield of physics. Astron­ omers use the principles of physics and mathematics to learn about the fundamental nature of the universe, including the sun, moon, planets, stars, and galaxies. They apply their knowledge to problems in navigation and space flight. Most physicists work in research and development. Some do ba­ sic research to increase scientific knowledge. For example, they in­ vestigate the structure of the atom or the nature of gravity. Physicists who conduct applied research build upon the discover­ ies made through basic research and work to develop new devices, products, and processes. For instance, basic research in solid-state physics led to the development of transistors and then to the inte­ grated circuits used in computers. Physicists also design research equipment. This equipment often has additional unanticipated uses. For example, lasers are used in surgery; microwave devices are used for ovens; and measuring in­ struments can analyze blood or the chemical content of foods. A small number work in inspection, testing, quality control, and other production-related jobs in industry. Federal Reserve Bank of St. Louis  Much physics research is done in small or medium-size laborato­ ries. However, experiments in plasma, nuclear, high energy, and some other areas of physics require extremely large, expensive equipment such as particle accelerators. Physicists in these subfields often work in large teams. Although physics research may require extensive experimentation in laboratories, research physicists still spend time in offices planning, recording, analyzing, and reporting on research. Almost all astronomers do research. They analyze large quanti­ ties of data gathered by observatories and satellites and write scien­ tific papers or reports on their findings. Most astronomers spend only a few weeks each year making observations with optical telescopes, radio telescopes, and other instruments. Contrary to the popular image, astronomers almost never make observations by looking directly through a telescope because enhanced photo­ graphic and electronic detecting equipment can see more than the human eye. Most physicists specialize in one of many subfields—elementary particle physics; nuclear physics; atomic and molecular physics; physics of condensed matter (solid-state physics); optics; acoustics; plasma physics; or the physics of fluids. Some specialize in a subdivi­ sion of one of these subfields; for example, within condensed matter physics, specialties include superconductivity, crystallography, and semiconductors. However, all physics involves the same fundamen­ tal principles, so specialties may overlap, and physicists may switch from one subfield to another. Also, growing numbers of physicists work in combined fields such as biophysics, chemical physics, and geophysics. Working Conditions Physicists often work regular hours in laboratories and offices. At times, however, those who are deeply involved in research may work long or irregular hours. Most do not encounter unusual hazards in their work. Some physicists work away from home tem­ porarily at national or international facilities with unique equipment such as particle accelerators. Astronomers who make observations may travel to observatories, which are usually in remote locations, and routinely work at night. Employment Physicists and astronomers held nearly 21,000 jobs in 1992. Also, a significant number held physics or astronomy faculty positions in colleges and universities. (See the statement on college and univer­ sity faculty elsewhere in the Handbook.) About two-fifths of all nonfaculty physicists worked for research, development, and testing laboratories in industry. The Federal Government employed almost one-fifth, mostly in the Departments of Defense and Commerce and in the National Aeronautics and Space Administration. Others worked in colleges and universities in nonfaculty positions and for  Research and development work is an integral part of most physicists’ jobs. 23  aerospace firms, noncommercial research laboratories, electrical equipment manufacturers, engineering services firms, and the trans­ portation equipment industry. Although physicists are employed in all parts of the country, most work in areas that have universities and large research and de­ velopment laboratories. Training, Other Qualifications, and Advancement A doctoral degree is the usual educational requirement for physi­ cists and astronomers, because most jobs are in research and devel­ opment or in teaching at large universities or 4-year colleges. Those having bachelor’s or master’s degrees in physics are gener­ ally qualified to work in an engineering-related area or other scien­ tific fields, to work as technicians, or to assist in setting up laborato­ ries. Some may qualify for applied research jobs in private industry or nonresearch positions in the Federal Government, and a master’s degree often suffices for teaching jobs in 2-year colleges. Astronomy bachelor’s degree holders often enter a field unrelated to astronomy, but they are also qualified to work in planetariums running science shows or to assist astronomers doing research. (See statements on engineers, geologists and geophysicists, computer programmers, and computer scientists and systems analysts elsewhere in the Handbook.) About 750 colleges and universities offer a bachelor’s degree in physics. The undergraduate program provides a broad background in the natural sciences and mathematics. Typical physics courses in­ clude mechanics, electromagnetism, optics, thermodynamics, atomic physics, and quantum mechanics. About 180 colleges and universities have physics departments which offer Ph.D. degrees in physics. Graduate students usually concentrate in a subfield of physics such as elementary particles or condensed matter. Many begin studying for their doctorate immedi­ ately after their bachelor’s degree. About 72 universities offer the Ph.D. degree in astronomy, either through an astronomy department, a physics department, or a com­ bined physics/astronomy department. Applicants to astronomy doctoral programs face keen competition for available slots. Those planning a career in astronomy should have a very strong physics background—in fact, an undergraduate degree in physics is excel­ lent preparation, followed by a Ph.D. in astronomy. Mathematical ability, computer skills, an inquisitive mind, imagi­ nation, and the ability to work independently are important traits for anyone planning a career in physics or astronomy. Prospective physicists who hope to work in industrial laboratories applying physics knowledge to practical problems should broaden their edu­ cational background to include courses outside of physics, such as economics, computer technology, and current affairs. Good oral and written communication skills are also becoming increasingly important. Most Ph.D. physics and astronomy graduates choose to take a postdoctoral position, which is helpful for those who want to con­ tinue research in their specialty and for those who plan a career teaching at the university level. Beginning physicists, especially those without a Ph.D., often do routine work under the close super­ vision of more senior scientists. After some experience, they are as­ signed more complex tasks and given more independence. Physicists who develop new products or processes sometimes form their own companies or join new firms to exploit their own ideas. Job Outlook A large proportion of physicists and astronomers are employed on research projects, many of which, in the past, were defense related. Expected reductions in defense-related research and an expected slowdown in the growth of civilian physics-related research will cause employment of physicists and astronomers to decline through the year 2005. Since the number of doctorates granted in physics is not expected to decrease much from present levels, competition is expected for the kind of research and academic jobs that those with new doctorates in physics have traditionally sought. Although research and development budgets in private industry will continue to grow, many research laboratories in private indus­ try are expected to reduce basic research, which is where much 24 Federal Reserve Bank of St. Louis  physics research takes place, in favor of applied research and prod­ uct and software development. Furthermore, although the number of retiring academic physicists is expected to increase in the late 1990’s, it is possible that many of them will not be replaced or will be replaced by faculty in other disciplines. Persons with only a bachelor’s degree in physics are not qualified to enter most physicist jobs. However, many find jobs as high school physics teachers and in engineering, technician, mathematics, and computer- and environment-related occupations. (See the state­ ments on these occupations elsewhere in the Handbook.) Also, those with advanced degrees in physics will find their skills transferrable to many other occupations. Earnings Starting salaries for physicists averaged about $30,000 a year in 1992 for those with a bachelor’s or master’s degree, and about $41,000 for those with a doctoral degree, according to the College Placement Council. The American Institute of Physics reported a median salary of $65,000 in 1992 for its members with Ph.D.’s. Those working in 4year colleges (9-10 months a year) earned the least—$43,000— while those employed in industry and hospitals earned the most— $71,500 and 78,000, respectively. Average earnings for physicists in nonsupervisory, supervisory, and managerial positions in the Federal Government in 1993 were $61,956 a year, and for astronomy and space scientists, $65,709. Related Occupations The work of physicists and astronomers relates closely to that of other scientific and mathematic occupations such as chemist, geolo­ gist, geophysicist, and mathematician. Engineers and engineering and science technicians also use the principles of physics in their work.

Drafters (D.O.T. 001.261-010, -014; 002.261; 003.131, .261 except-010, 281;005.281007.161-010, -014, and -018, .261, and .281; 010.281 except -022; 014.281; 017 except .261-010 and .684; and 726.364-014)  Nature of the Work Drafters prepare technical drawings used by production and con­ struction workers to build spacecraft, automobiles, industrial ma­ chinery and other manufactured products, as well as structures such as office buildings, houses, bridges, and oil and gas pipelines. Their drawings show the technical details of the products and structures from all sides, with exact dimensions, the specific materials to be used, procedures to be followed, and other information needed to carry out the job. Drafters prepare and fill in technical details, using drawings, rough sketches, specifications, and calculations made by engineers, surveyors, architects, and scientists. For example, work­ ing from rough sketches, drafters use knowledge of standardized building techniques to draw the details of a structure, or employ knowledge of engineering and manufacturing theory to arrange the parts of a machine and determine the number and kind of fasteners needed. For this, they may use technical handbooks, tables, calcula­ tors, and computers.  There are two methods by which drawings are prepared. In the traditional method, drafters sit at drawing boards and use com­ passes, dividers, protractors, triangles, and other drafting devices to prepare the drawing manually. Drafters also use computer-aided drafting (CAD) systems. They use computer work stations to create the drawing on a video screen. They may print the drawing on paper but also store it electronically so that revisions and/or duplications can be made more easily. These systems also permit drafters to eas­ ily prepare many variations of a design. When CAD systems were first introduced, some thought a new occupation—CAD operator—would result. It is now apparent that a person who produces a technical drawing using CAD is still a drafter, and needs all the knowledge of traditional drafters as well as CAD skills. Because the cost of CAD systems is dropping rapidly, by the year 2005 it is likely that almost all drafters will use CAD systems regu­ larly. However, manual drafting probably will still be used in certain applications, especially in low-volume firms that produce many oneof-a-kind drawings with little repetition. Many drafters specialize. Architectural drafters draw architec­ tural and structural features of buildings and other structures. They may specialize by the type of structure, such as schools or office buildings, or by material, such as reinforced concrete or stone. Aeronautical drafters prepare engineering drawings used for the manufacture of aircraft and missiles. Electrical drafters draw wiring and layout diagrams used by workers who erect, install, and repair electrical equipment and wir­ ing in powerplants, electrical distribution systems, and buildings. Electronic drafters draw wiring diagrams, circuit board assembly diagrams, schematics, and layout drawings used in the manufac­ ture, installation, and repair of electronic equipment. Civil drafters prepare drawings and topographical and relief maps used in civil engineering projects such as highways, bridges, pipe­ lines, flood control projects, and water and sewage systems. Mechanical drafters draw detailed working diagrams of machin­ ery and mechanical devices, including dimensions, fastening meth­ ods, and other engineering information. Working Conditions Drafters usually work in offices or rooms with lighting appropriate to their tasks. They often sit at drawing boards or computer termi­ nals for long periods of time doing detailed work, which may cause  Computer-aided design systems enable drafters to make revisions to designs more easily.

Drafters who spend the majority of their time using a computer keyboard for CAD work risk repetitive motion injuries, such as carpal tunnel syndrome. Employment Drafters held about 314,000 jobs in 1992. Over one-third of all drafters worked in engineering and architectural services, firms that design construction projects or do other engineering work on a con­ tract basis for organizations in other parts of the economy; about one-third worked in durable goods manufacturing industries, such as machinery, electrical equipment, and fabricated metals; and the remainder were mostly employed in the construction, communica­ tions, utilities, and personnel supply services industries. About 11,000 drafters worked in government in 1992, primarily at the State and local level. Training, Other Qualifications, and Advancement Employers prefer applicants for drafting positions who have posthigh school training in technical institutes, junior and community colleges, or extension divisions of universities. Employers are most interested in applicants who have well-developed drafting and mechanical drawing skills, a solid background in computer-aided design techniques, and courses in mathematics, science, and engi­ neering technology. Many types of publicly and privately operated schools provide drafting training. The kind and quality of programs can vary consid­ erably. Therefore, prospective students should be careful in select­ ing a program. They should contact prospective employers regard­ ing their preferences and ask schools to provide information about the kinds of jobs obtained by graduates, instructional facilities and equipment, and faculty qualifications. Technical institutes offer intensive technical training but less the­ ory and general education than junior and community colleges. Many offer 2-year associate degree programs, which are similar to or part of the programs offered by community colleges or State uni­ versity systems. Other technical institutes are run by private, often for- profit, organizations, sometimes called proprietary schools; their programs vary considerably in length and types of courses of­ fered. Some are 2-year associate degree programs. Junior and community colleges offer curriculums similar to those in technical institutes but may include more theory and liberal arts. Often there may be little or no difference between technical institute and community college programs. However, courses taken at junior or community colleges are more likely to be accepted for credit at 4year colleges than those at technical institutes. After completing the 2-year program, some graduates qualify for jobs as drafters while others continue their education in a related field at 4-year colleges. Four-year colleges usually do not offer drafting training, but col­ lege courses in engineering, architecture, and mathematics are use­ ful for obtaining a job as a drafter. Area vocational-technical schools are postsecondary public institu­ tions that serve local students and emphasize training needed by lo­ cal employers. Most require a high school diploma or its equivalent for admission. Other training may be obtained in the Armed Forces in technical areas which can be applied in civilian drafting jobs. Some additional training may be needed, depending on the military skills acquired and the kind ofjob, but often this is gained on the job. Those planning careers in drafting should be able to draw free­ hand three-dimensional objects and do detailed work accurately and neatly. Artistic ability is helpful in some specialized fields, as is knowledge of manufacturing and construction methods. In addi­ tion, prospective drafters should have good communication skills because they work closely with engineers, surveyors, architects, and other workers. In 1992, the American Design Drafting Association (ADDA) es­ tablished a certification program for drafters. Although drafters are not required to be certified, certification demonstrates to employers that nationally recognized standards have been met. Individuals who wish to become certified must pass the Drafter Certification Test, which is administered periodically at ADDA-authorized test sites. Applicants are tested on their knowledge and understanding of 25  basic drafting concepts such as geometric construction, working drawings, and architectural terms and standards. Entry level drafters usually do routine work under close supervi­ sion. After gaining experience, they do more difficult work with less supervision and may advance to senior drafter, designer, or supervi­ sor. With appropriate college courses, they may become engineers or architects. Job Outlook Employment of drafters is expected to grow more slowly than the average for all occupations through the year 2005. Industrial growth and the increasingly complex design problems associated with new products and processes will increase the demand for draft­ ing services. However, greater use of CAD equipment by architects and engineers, as well as drafters, is expected to offset some of this growth in demand. Although productivity gains from CAD have been relatively modest since CAD use became widespread, CAD technology continues to advance. CAD is expected to become an in­ creasingly powerful tool, simplifying many traditional drafting tasks. Nevertheless, as in other areas, the ease of obtaining com­ puter-generated information stimulates a demand for more informa­ tion, so there will continue to be growth in the occupation. Individu­ als who have at least 2 years of training in a technically strong drafting program and who have experience with CAD systems will have the best opportunities. Although growth in employment will create many job openings, most job openings are expected to arise as drafters retire or leave the labor force for other reasons. Drafters are highly concentrated in industries that are sensitive to cyclical swings in the economy, such as engineering and architec­ tural services and durable goods manufacturing. During recessions, when fewer buildings are designed, drafters may be laid off. Earnings Median annual earnings of drafters who worked year round, full time were about $27,400 in 1992; the middle 50 percent earned be­ tween $20,600 and $35,100 annually; 10 percent earned more than $43,500; 10 percent earned less than $15,900. According to a survey of workplaces in 160 metropolitan areas, experienced drafters had median earnings of about $30,200 a year in 1992, with the middle half earning between about $27,100 and $34,000 a year. Related Occupations Other workers who prepare or analyze detailed drawings and make precise calculations and measurements include architects, land­ scape architects, engineers, engineering technicians, science techni­ cians, photogrammetrists, cartographers, and surveyors.

Their jobs are more limited in scope and more practically ori­ ented than those of scientists and engineers. Many engineering 26 Federal Reserve Bank of St. Louis  technicians assist engineers and scientists, especially in research and development. Others work in production or inspection jobs. Engineering technicians who work in research and development build or set up equipment, prepare and conduct experiments, calcu­ late or record the results, and help engineers in other ways. Some make prototype versions of newly designed equipment. They also assist in routine design work, often using computer-aided design equipment. Engineering technicians who work in manufacturing follow the general directions of engineers. They may prepare specifications for materials, devise and run tests to ensure product quality, or study ways to improve manufacturing efficiency. They may also supervise production workers to make sure they follow prescribed procedures. Civil engineering technicians help civil engineers plan and build highways, buildings, bridges, dams, wastewater treatment systems, and other structures and do related surveys and studies. Some in­ spect water and wastewater treatment systems to ensure that pollu­ tion control requirements are met. Others estimate construction costs and specify materials to be used. (See statement on cost estima­ tors elsewhere in the Handbook.) Electronics engineering technicians help develop, manufacture, and service electronic equipment such as radios, radar, sonar, televi­ sion, industrial and medical measuring or control devices, naviga­ tional equipment, and computers, often using measuring and diag­ nostic devices to test, adjust, and repair equipment. Workers who only repair electrical and electronic equipment are discussed in sev­ eral other statements elsewhere in the Handbook. Many of these re­ pairers are often called electronics technicians. Industrial engineering technicians study the efficient use of per­ sonnel, materials, and machines in factories, stores, repair shops, and offices. They prepare layouts of machinery and equipment, plan the flow of work, make statistical studies, and analyze production costs. Mechanical engineering technicians help engineers design and de­ velop machinery, robotics, and other equipment by making sketches and rough layouts. They also record data, make computations, ana­ lyze results, and write reports. When planning production, mechan­ ical engineering technicians prepare layouts and drawings of the as­ sembly process and of parts to be manufactured. They estimate labor costs, equipment life, and plant space. Some test and inspect machines and equipment in manufacturing departments or work with engineers to eliminate production problems. Chemical engineering technicians are usually employed in indus­ tries producing pharmaceuticals, chemicals, and petroleum prod­ ucts, among others. They help design, install, and test or maintain process equipment or computer control instrumentation, monitor quality control in processing plants, and make needed adjustments. Working Conditions Most engineering technicians work regular hours in laboratories, of­ fices, electronics and industrial plants, or construction sites. Some may be exposed to hazards from equipment, chemicals, or toxic materials. Employment Engineering technicians held about 695,000 jobs in 1992. About two-fifths worked in manufacturing, mainly in the electrical and electronic machinery and equipment, transportation equipment, in­ dustrial machinery equipment, and computer and office equipment industries. Over one-fourth worked in service industries, mostly in engineering or business services companies who do engineering work on contract for government, manufacturing, or other organi­ zations. In 1992, the Federal Government employed about 59,000 engi­ neering technicians. Major employers were the Departments of De­ fense, Transportation, Agriculture, and the Interior, the Tennessee Valley Authority, and the National Aeronautics and Space Admin­ istration. State governments employed about 30,000 and local gov­ ernments about 28,000. Training, Other Qualifications, and Advancement Although it is possible to qualify for some engineering technician jobs with no formal training, most employers prefer to hire someone  man»  Like engineers, engineering technicians specialize in a specific area, such as mechanics, electronics, or chemicals. who will require less on-the-job training and supervision. Training is available at technical institutes, junior and community colleges, ex­ tension divisions of colleges and universities, public and private vo­ cational-technical schools, and through some technical training pro­ grams in the Armed Forces. Persons with college courses in science, engineering, and mathematics may also qualify for some positions but may need additional specialized training and experience. Many types of publicly and privately operated schools provide technical training. The kind and quality of programs vary consider­ ably. Therefore, prospective students should be careful in selecting a program. They should contact prospective employers regarding their preferences and ask schools to provide information about the kinds of jobs obtained by graduates, instructional facilities and equipment, and faculty qualifications. Graduates of programs ac­ credited by the Accreditation Board of Engineering and Technology (ABET) are generally recognized to have achieved a minimum level of competence in the mathematics, science, and technical courses re­ quired for this occupation. Technical institutes offer intensive technical training but less the­ ory and general education than junior and community colleges. Many offer 2-year associate degree programs, and are similar to or are part of a community college or are part of State university sys­ tems. Other technical institutes are run by private, often for-profit, organizations, sometimes called proprietary schools; their programs vary considerably in length and types of courses offered. Some are 2year associate degree programs. Junior and community colleges offer curriculums similar to those in technical institutes but may include more theory and liberal arts. Often there may be little or no difference between technical institute and community college programs, as both offer associate degrees. After completing the 2-year program, some graduates get jobs as en­ gineering technicians, while others continue their education at 4year colleges. However, there is a difference between an associate degree in pre-engineering and one in engineering technology. Stu­ dents who enroll in a 2-year pre-engineering program may find it very difficult to find work as an engineering technician should they decide not to enter a 4-year engineering program because pre-engi­ neering programs usually focus less on hands-on applications and more on academic preparatory work. Conversely, graduates of 2year engineering technology programs may not receive credit for many of the courses they have taken if they choose to transfer to a 4year engineering program. Federal Reserve Bank of St. Louis  Four-year colleges usually do not offer engineering technician training, but college courses in science, engineering, and mathemat­ ics are useful for obtaining a job as an engineering technician. Many 4-year colleges offer bachelor’s degrees in engineering technology, but graduates of these programs are often hired to work as applied engineers, not technicians. Area vocational-technical schools include postsecondary public in­ stitutions that serve local students and emphasize training needed by local employers. Most require a high school diploma or its equivalent for admission. Other training in technical areas may be obtained in the Armed Forces. Many military technical training programs are highly re­ garded by employers. Some additional training may be needed, de­ pending on the military skills acquired and the kind ofjob, but often this is gained on the job. Some correspondence schools also offer training for engineering technicians. Prospective engineering technicians should take as many high school science and math courses as possible. Engineering techni­ cians need an aptitude for mathematics and science. For design work, creativity also is desirable. They should be able to work well with others since they are often part of a team of engineers and other technicians. Those in sales and service should be able to work inde­ pendently and deal effectively with customers. Engineering technicians usually begin by doing routine work under the close supervision of an experienced technician, engineer, or scientist. As they gain experience, they are given more difficult assignments with only general supervision. Some engineering tech­ nicians eventually become supervisors. Job Outlook Well-qualified engineering technicians should experience good em­ ployment opportunities through the year 2005. Employment is ex­ pected to increase as fast as the average for all occupations due to ex­ pected continued growth in the output of technical products. Competitive pressures and advancing technology will force compa­ nies to improve and update manufacturing facilities and product de­ signs more rapidly than in the past. However, like engineers, em­ ployment of engineering technicians is influenced by local and national economic conditions. The employment outlook also varies with the area of specialization and industry. Some types of engineer­ ing technicians, such as civil engineering and aeronautical engineer­ ing technicians, experience greater cyclical fluctuations than others. Technicians whose jobs are defense related may experience fewer opportunities because of defense cutbacks. In addition to growth, nearly as many job openings will be to re­ place technicians who retire or leave the labor force for other rea­ sons. Earnings According to a survey of workplaces in 160 metropolitan areas, en­ gineering technicians at the most junior level had median earnings of about $20,900 in 1992, with the middle half earning between about $18,900 and $22,600 a year. Engineering technicians with more experience and the ability to work with little supervision had median earnings of about $28,800, and those in supervisory or se­ nior level positions earned about $41,400. In the Federal Government, engineering technicians could start at about $14,600, $16,400, or $18,300 in 1993, depending on their education and experience. In 1993, the average annual salary for en­ gineering technicians in supervisory, nonsupervisory, and manage­ ment positions in the Federal Government was $37,337; for elec­ tronics technicians, $42,436; and for industrial engineering technicians, $38,006. Related Occupations Engineering technicians apply scientific and engineering principles usually acquired in postsecondary programs below the baccalaure­ ate level. Similar occupations include science technicians, drafters, surveyors, broadcast technicians, and health technologists and tech­ nicians. 27  Sources of Additional Information A number of engineering technology-related organizations provide information on engineering technician and technology careers.

Science Technicians (List of D.O.T. codes available on request from the Chief, Division of Occupational Outlook, Bureau of Labor Statistics, Washington, DC 20212.)  Nature of the Work Science technicians use the principles and theories of science and mathematics to solve problems in research and development and to investigate, invent, and help improve products. Their jobs are more practically oriented than those of scientists. In recent years, laboratory instrumentation and procedures have become more complex, changing the work of science technicians in research and development. The increasing use of robotics to per­ form many routine tasks formerly done by technicians has freed technicians to operate other, more sophisticated laboratory equip­ ment. Science technicians make extensive use of computers, com­ puter-interfaced equipment, robotics, and high-technology indus­ trial applications such as biological engineering. Technicians set up, operate, and maintain laboratory instru­ ments, monitor experiments, calculate and record results, and often develop conclusions. Those who work in production test products for proper proportions of ingredients or for strength and durability. Agricultural technicians work with agricultural scientists in food and fiber research, production, and processing. Some conduct tests and experiments to improve the yield and quality of crops or to in­ crease the resistance of plants and animals to disease, insects, or other hazards. Other agricultural technicians do animal breeding and nutrition work. Biological technicians work with biologists, studying living orga­ nisms. They may assist scientists who conduct medical research, helping to find a cure for cancer or AIDS, for example, or they may help conduct pharmaceutical research. Biological technicians also analyze organic substances such as blood, food, and drugs; some ex­ amine evidence in criminal investigations. Biological technicians working in biotechnology labs use the knowledge and techniques gained from basic research by scientists, including gene splicing and recombinant DNA, and apply these techniques in product develop­ ment. Chemical technicians work with chemists and chemical engineers, developing and using chemicals and related products and equip­ ment. Most do research and development, testing, or other labora­ tory work. For example, they might test packaging for design, materials, and environmental acceptability; assemble and operate new equipment to develop new products; monitor product quality; or develop new production techniques. Some chemical technicians collect and analyze samples of air and water to monitor pollution levels. Those who focus on basic research might produce com­ pounds through complex organic synthesis. Nuclear technicians operate nuclear test and research equipment, monitor radiation, and assist nuclear engineers and physicists in re­ search. Some also operate remote control equipment to manipulate radioactive materials or materials to be exposed to radioactivity. Petroleum technicians measure and record physical and geologic conditions in oil or gas wells using instruments lowered into wells orby analysis of the mud from wells. In oil and gas exploration, they 28 Federal Reserve Bank of St. Louis  collect and examine geological data or test geological samples to de­ termine petroleum and mineral content. Some petroleum techni­ cians, called scouts, collect information about oil and gas well drill­ ing operations, geological and geophysical prospecting, and land or lease contracts. Other science technicians collect weather information or assist oceanographers. Working Conditions Science technicians work under a wide variety of conditions. Many work indoors, usually in laboratories, and have regular hours. Some occasionally work irregular hours to monitor experiments that can’t be completed during regular working hours. Others, such as agricul­ tural and petroleum technicians, perform much of their work out­ doors, sometimes in remote locations, and some may be exposed to hazardous conditions. Chemical technicians sometimes work with toxic chemicals; nuclear technicians may be exposed to radiation; and biological technicians sometimes work with disease-causing or­ ganisms or radioactive agents. However, there is little risk if proper safety procedures are followed. Employment Science technicians held about 244,000 jobs in 1992. Nearly 40 per­ cent worked in manufacturing, mostly in the chemical industry, but also in the petroleum refining and food processing industries. Al­ most 20 percent worked in colleges and universities and another 12 percent worked in research and testing services. In 1992, the Federal Government employed about 19,000 science technicians, mostly in the Departments of Defense, Agriculture, In­ terior, and Commerce. Training, Other Qualifications, and Advancement There are several ways to qualify for a job as a science technician. Most employers prefer applicants who have at least 2 years of spe­ cialized training. Many junior and community colleges offer associ­ ate degrees in a specific technology or a more general education in science and mathematics. A number of 2-year associate degree pro­ grams are designed to provide easy transfer to a 4-year college or university if desired. Technical institutes generally offer technician training but provide less theory and general education than junior or community colleges. The length cf piograms at technical institutes  Employers seek well trained individuals with good laboratory skills for science technician positions.  varies, although 2-year associate degree programs are common. Some of these schools offer cooperative-education programs, al­ lowing students the opportunity to work at a local company while attending classes in alternate terms. Many science technicians have a bachelor’s degree in science or mathematics, or have had science and math courses in 4-year colleges. Some people with bachelor’s degrees in a physical or life science become science technicians be­ cause they can’t find or don’t want a job as a scientist or because em­ ployers couldn’t find properly trained technicians with less educa­ tion. In some cases, they may be able to move into jobs as scientists, managers, or technical sales workers. Some companies offer formal or on-the-job training for science technicians. Technicians also may qualify for their jobs with some types of Armed Forces training. Persons interested in careers as science technicians should take as many high school science and math courses as possible. Science courses taken beyond high school, in an associate’s or bachelor’s program, should be laboratory oriented, with an emphasis on “bench” skills. Because computers and computer-interfaced equip­ ment are often used in research and development laboratories, tech­ nicians should have strong computer skills. Communication skills are important, and technicians should be able to work well with others since technicians often are part of a team. Technicians usually begin work as trainees in routine positions under the direct supervision of a scientist or experienced technician. Job candidates whose training or educational background encom­ passes extensive hands-on experience with a variety of laboratory equipment, including computers and related equipment, usually re­ quire a much shorter period of on-the-job training. As they gain ex­ perience, they take on more responsibility and carry out assign­ ments under only general supervision. Some eventually become supervisors. Job Outlook Employment of science technicians is expected to increase about as fast as the average for all occupations through the year 2005. Con­ tinued growth of scientific research and development and the pro­ duction of technical products should spur demand for all science technicians. Advances in biotechnology will increase the need for bi­ ological technicians in particular. However, growth of job openings will be moderated somewhat by an expected slowdown in overall employment growth in the chemical industry, where many chemical technicians are employed. Nevertheless, job opportunities are expected to be very good for graduates of science technician training programs who are welltrained on the equipment currently in use in industrial and govern­ ment laboratories. As the instrumentation and techniques used in industrial research and development laboratories becomes more complex, employers are seeking well trained individuals with highly developed technical and communication skills. Despite the projected growth, most job openings will arise from the need to replace technicians who retire or leave the labor force for other reasons. Earnings Median annual earnings of science technicians were about $25,300 in 1992; the middle 50 percent earned between $18,700 and $33,400. Ten percent earned less than $14,400, and 10 percent earned over $42,400. At all income levels, chemical technicians earned signifi­ cantly more than biological technicians. In the Federal Government in 1993, science technicians could start at $14,600, $16,390, or $18,340, depending on their education and experience. The average annual salary for biological science technicians in nonsupervisory, supervisory, and managerial posi­ tions employed by the Federal Government in 1993 was $24,828; for mathematical technicians, $29,239; for physical science technicians, $31,484; for geodetic technicians, $37,282; for hydrologic techni­ cians, $28,635; and for meteorologic technicians, $36,408. Related Occupations Other technicians who apply scientific principles at a level usually taught in 2-year associate degree programs include engineering Federal Reserve Bank of St. Louis  technicians, broadcast technicians, drafters, and health technolo­ gists and technicians. Some of the work of agricultural and biologi­ cal technicians is related to that in agriculture and forestry occupa­ tions.

Surveyors (D.O.T. 018 except .167-022, and 024.061-014)  Nature of the Work This statement covers three groups of workers who measure and map the earth’s surface. Land surveyors establish official land, air space, and water boundaries. They write descriptions of land for deeds, leases, and other legal documents; define air space for air­ ports; and measure construction and mineral sites. They are assisted by survey technicians, who operate surveying instruments and col­ lect information. Mapping scientists and other surveyors collect geo­ graphic information and prepare maps and charts of large areas. Land surveyors manage one or more survey parties that measure distances, directions, and angles between points and elevations of points, lines, and contours on the earth’s surface. They plan the fieldwork, select known survey reference points, and determine the precise location of all important features of the survey area. They re­ search legal records and look for evidence of previous boundaries. They record the results of the survey, verify the accuracy of data, and prepare plats, maps, and reports. Surveyors who establish offi­ cial boundaries must be licensed by the State in which they work. The information needed by the land surveyor is gathered by a sur­ vey party. A typical survey party is made up of a party chief and sev­ eral survey technicians and helpers. The party chief, who may be ei­ ther a land surveyor or a senior survey technician, leads the day-to­ day work activities. The party chief is assisted by survey technicians, who adjust and operate surveying instruments such as the theodolite (used to measure horizontal and vertical angles) and electronic dis­ tance-measuring equipment. Survey technicians or helpers position and hold the vertical rods or targets that the theodolite operator sights on to measure angles, distances, or elevations. They may also hold measuring tapes and chains if electronic distance-measuring equipment is not used. Survey technicians also compile notes, make sketches, and enter the data obtained from these instruments into computers. Some survey parties include laborers or helpers to clear brush from sight lines, drive stakes, carry equipment, and perform other less skilled duties. New technology is changing the nature of the work of surveyors and survey technicians. For larger surveying projects, surveyors are increasingly using the Global Positioning System (GPS), a satellite system which precisely locates points on the earth using radio sig­ nals transmitted by satellites. To use it, a surveyor places a satellite receiver—about the size of a backpack—on a desired point. The re­ ceiver collects information from several differently positioned satel­ lites at once to locate its precise position. Two receivers are gener­ ally operated simultaneously, one at a known point and the other at the unknown point. The receiver can also be placed in a vehicle to trace out road systems, or for other uses. As the cost of the receivers falls, much more surveying work will be done by GPS. Mapping scientists, like land surveyors, measure, map, and chart the earth’s surface but generally cover much larger areas. Unlike land surveyors, however, mapping scientists work mainly in offices and may seldom or never visit the sites they are mapping. Mapping scientists include workers in several occupations. Cartographers pre­ pare maps using information provided by geodetic surveys, aerial photographs, and satellite data. Photogrammetrists prepare maps and drawings by measuring and interpreting aerial photographs, us­ ing analytical processes and mathematical formulas. Photogramme­ trists make detailed maps of areas that are inaccessible or difficult to survey by other methods. Map editors develop and verify map con­ tents from aerial photographs and other reference sources. 29  Some surveyors perform specialized functions which are closer to mapping science than traditional surveying. Geodetic surveyors use high-accuracy techniques, including satellite observations, to mea­ sure large areas of the earth’s surface. Geophysical prospecting sur­ veyors mark sites for subsurface exploration, usually petroleum re­ lated. Marine surveyors survey harbors, rivers, and other bodies of water to determine shorelines, topography of the bottom, water depth, and other features. The work of mapping scientists is also changing due to new tech­ nologies. The technologies include the GPS, Geographic Informa­ tion Systems (GIS)—which are computerized data banks of spatial data—new earth resources data satellites, and improved aerial pho­ tography. From the older specialties of photogrammetrist or cartog­ rapher, a new type of mapping scientist is emerging. The geographic information specialist combines the functions of mapping science and surveying into a broader field concerned with the collection and analysis of geographic spatial information. Working Conditions Surveyors usually work an 8-hour day, 5 days a week, and spend a lot of their time outdoors. Sometimes they work longer hours during the summer, when weather and light conditions are most suitable for fieldwork. Land surveyors and technicians do active and sometimes strenu­ ous work. They often stand for long periods, walk long distances, and climb hills with heavy packs of instruments and equipment. They also are exposed to all types of weather. Occasionally, they may commute long distances, stay overnight, or even temporarily relocate near a survey site. Surveyors also spend considerable time in offices, planning surveys, analyzing data, and preparing reports and maps. Most computations and map drafting are done at a computer. Mapping scientists spend almost all their time in offices. Employment Surveyors held about 99,000 jobs in 1992. Engineering, architec­ tural, and surveying firms employed nearly three-fifths of all survey­ ors. Federal, State, and local government agencies employed an ad­ ditional one-fourth. Major Federal Government employers are the U.S. Geological Survey, the Bureau of Land Management, the Army Corps of Engineers, the Forest Service, the National Oceanic and Atmospheric Administration, and the Defense Mapping Agency. Most surveyors in State and local government work for  *  _____  Land surveyors measure distances and elevations along the earth’s surface. 30 Federal Reserve Bank of St. Louis  highway departments and urban planning and redevelopment agen­ cies. Construction firms, mining and oil and gas extraction compa­ nies, and public utilities also employ surveyors. About 10,000 sur­ veyors were self-employed. Training, Other Qualifications, and Advancement Most persons prepare to be a licensed surveyor by combining post­ secondary school courses in surveying with extensive on-the-job training. About 25 universities offer 4-year programs leading to a BS degree in surveying. Junior and community colleges, technical insti­ tutes, and vocational schools offer 1-, 2-, and 3-year programs in both surveying and surveying technology. High school students interested in surveying should take courses in algebra, geometry, trigonometry, drafting, mechanical drawing, and computer science. All 50 States license land surveyors. For licensure, most State li­ censing boards require that individuals pass two written examina­ tions, one prepared by the State and one given by the National Council of Examiners for Engineering and Surveying. In addition, they must meet varying standards of formal education and work ex­ perience in the field. In the past, many surveyors started as members of survey crews and worked their way up to licensed surveyor with little formal training in surveying. However, due to advancing tech­ nology and an increase in licensing standards, more formal educa­ tion is now required. Most States at the present time require some formal post-high school education courses and 5 to 12 years of sur­ veying experience to gain licensure. However, requirements vary among the States. Generally, the quickest route is a combination of 4 years of college, 2 to 4 years of experience (a few States do not re­ quire any), and passing the licensing examinations. An increasing number of States require a bachelor’s degree in surveying or in a closely related field such as civil engineering or forestry with courses in surveying. High school graduates with no formal training in surveying usu­ ally start as a helper. Beginners with postsecondary school training in surveying can generally start as technicians. With on-the-job ex­ perience and formal training in surveying—either in an institutional program or from a correspondence school—workers may advance to senior survey technician, then to party chief, and finally, in some cases, to licensed surveyor (depending on State licensing require­ ments). The American Congress on Surveying and Mapping has a volun­ tary certification program for survey technicians. Technicians are certified at four levels that require progressive amounts of experi­ ence; technicians who qualify are certified at a higher level after passing a written examination. Although not required for State li­ censure, many employers require certification for promotion to more responsible positions. Cartographers and photogrammetrists usually have a bachelor’s de­ gree in engineering or a physical science, although it is possible to enter these jobs through experience as a photogrammetric or cartographic technician. Most cartographic and photogrammetry technicians have had some specialized postsecondary school training. With the develop­ ment of Geographic Information Systems, cartographers, photogram­ metrists, and other mapping scientists now need more education and ex­ perience in the use of computers than in the past. The American Society for Photogrammetry and Remote Sensing has voluntary certification programs for photogrammetrists and mapping scientists. To qualify for these professional distinctions, in­ dividuals must meet work experience standards and pass an oral or written examination. Surveyors should have the ability to visualize objects, distances, sizes, and other abstract forms and to work precisely and accurately because mistakes can be very costly. Surveying is a cooperative pro­ cess, so good interpersonal skills and the ability to work as part of a team are important. Leadership qualities are important for party chief and other supervisory positions. Members of a survey party must be in good physical condition to work outdoors and carry equipment over difficult terrain. They also need good eyesight, coordination, and hearing to communicate by hand or voice signals. Job Outlook Employment of surveyors is expected to grow more slowly than the average for all occupations through the year 2005. In addition to openings arising from growth in demand for surveyors, many will  result from the need to replace those who transfer to other occupa­ tions or leave the labor force. Growth in construction through the year 2005 should create jobs for surveyors who lay out streets, shopping centers, housing devel­ opments, factories, office buildings, and recreation areas. Road and highway construction and improvement also should create new sur­ veying positions. However, employment may fluctuate from year to year along with construction activity. Some growth in employment of mapping scientists and other sur­ veyors may occur in private firms; little or no growth is expected in the Federal Government. As a result of trends towards more complex technology, upgraded licensing requirements, and the increased demand for geographic spatial data (as opposed to traditional surveying services), opportu­ nities will be best for surveyors and mapping scientists who have at least a bachelor’s degree. New technology such as GPS and GIS may increase productivity for larger projects and may enhance em­ ployment opportunities for surveyors and survey technicians who have the educational background to use it, but limit opportunities for those with less education. Earnings In 1992, the median annual earnings for surveyors were about $26,800. The middle 50 percent earned between about $22,600 and $37,000 a year. The median annual earnings for survey technicians were about $23,700 a year in 1992. The middle 50 percent earned between $17,900 and $31,700 a year; 10 percent earned less than $14,500 a year; 10 percent earned more than $38,500 a year. In 1993, The Federal Government hired high school graduates with little or no training or experience at salaries or about $13,400  ☆ U.S. GOVERNMENT PRINTING OFFICE: 1994 363-539 2450-3 Federal Reserve Bank of St. Louis  annually for entry level jobs on survey crews. Those with 1 year of related postsecondary training earned about $14,600 a year. Those with an associate degree that included courses in surveying gener­ ally started as instrument assistants with an annual salary of about $16,400. In 1993, persons starting as land surveyors or cartogra­ phers with the Federal Government earned about $18,300 or $22,700 a year, depending on their qualifications. The average an­ nual salary for Federal land surveyors in 1993 was about $41,000, for cartographers, about $44,000, and for geodesists, about $47,600. The average annual salary for Federal surveying technicians was about $24,000, for cartographic technicians, about $30,100, and for geodetic technicians, about $37,300. Related Occupations Surveying is related to the work of civil engineers and architects, since an accurate survey is the first step in a construction project. Mapping science and geodetic surveying are related to the work of geologists and geophysicists, who study the earth’s internal compo­ sition, surface, and atmosphere. Mapping science is also related to the work of geographers and urban planners, who study how the earth’s surface is used.
