Nature of the Work
Engineering, science, and data processing managers plan, coordinate,
and direct technical, scientific, and computer related activities. They
supervise a staff of engineers, scientists, technicians, computer spe­
cialists, data processing workers, and support personnel.
Engineering, science, and data processing managers determine sci­
entific 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 development
of a large computer program, or advances in basic scientific research.
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 comple­
tion. They forecast costs and equipment and personnel needs for pro­
jects and programs. They hire and assign scientists, engineers,
technicians, computer specialists, data processing workers, and sup­
port personnel to carry out specific parts of the projects, supervise
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 managers; and
with contractors and equipment suppliers. They also establish work­
ing 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, directing
and coordinating the maintenance, operation, design, and installation
of equipment and machinery in industrial plants. Others manage
research and development activities that produce new products and
processes or improve existing ones.
Natural science managers oversee activities in agricultural science,
chemistry, biology, geology, meteorology, or physics. They manage
research and development projects and direct and coordinate 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 opera­
tions, 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.
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 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 occasion to
meet project deadlines. Some may experience considerable pressure
to meet technical or scientific goals within a short time or within a
tight budget.

Data processing managers review the work of staff members.
Employment
Engineering, science, and data processing managers held abou
315,000 jobs in 1990. Although these managers are found in almos
all industries, almost half are employed in manufacturing, especially
in the industrial machinery and equipment, electrical and electronic
equipment, transportation equipment, and chemicals industries. They
also work for engineering, management, and computer and data pro­
cessing services companies; as well as for government, colleges and
universities, and nonprofit research organizations. The majority are
engineering managers, often managing industrial research, develop­
ment, and design projects.
Training, Other Qualifications, and Advancement
Experience as an engineer, mathematician, natural scientist, or com­
puter professional is the usual requirement for becoming an engineer­
ing, science, or data processing manager. Consequently, educational
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, biol­
ogist, or other natural scientist. A large proportion of natural scien­
tists have a Ph.D. degree, especially those engaged in basic research,
although some in applied research and other activities have lesser
degrees. First-level science managers are usually specialists in the
work they supervise. For example, the manager of a group of physi­
cists doing optical research is almost always a physicist who is an
expert in optics.
Most data processing managers have been systems analysts,
although some may have experience as programmers or in other com­
puter specialties. There is no universally accepted way of preparing
for a job as a systems analyst, but a bachelor’s degree is usually
required. A graduate degree often is preferred. Many systems ana­
lysts have degrees in computer or information science, computer
information systems, or data processing and have experience as com­
puter programmers. A typical career advancement progression in a
large organization would be from programmer to programmer/ana­
lyst, to systems analyst, and then to project leader or senior analyst.
The first real managerial position might be as project manager, pro­
gramming 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. Supe­
riors also look for leadership and communication skills, as well as

managerial attributes such as the ability to make rational decisions, to
manage time well, to organize and coordinate work effectively, 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 pro­
moted but actually prefer doing technical work.
Some scientists and engineers become managers in marketing, per­
sonnel, purchasing, or other areas or become general managers.
Job Outlook
Employment of engineering and science managers is expected to
increase faster than the average for all occupations through the year
2005. Employment growth of each type of manager is expected to
correspond closely with growth of the occupation they supervise.
(See the statements on natural scientists, engineers, computer pro­
grammers, and systems analysts elsewhere in the Handbook.)
Underlying much of the growth of managers in science and engi­
neering is the expected continued growth of research and develop­
ment as companies update and improve products more frequently.
Increased research and investment in plants to expand output of
goods and services and to raise productivity also will add to employ­
ment requirements for science and engineering managers involved in
research and development, design, and the operation and maintenance
of production facilities. The development of new technologies in new
areas such as superconductivity, medical diagnostics, and advanced
materials also will help to develop newer, higher quality products.
Employment of data processing managers will increase as the econo­
my expands and as advances in technology lead to broader applica­
tions for computers.
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 special­
ists are eligible for management and seek promotion, there usually is
substantial competition for these jobs.
Earnings
Earnings for engineering, science, and data processing managers vary
by specialty and level of management. Salaries in 1990 ranged from
about $40,000 for first level data processing managers to well over
$100,000 for the most senior managers in large organizations, accord­
ing to the limited data available. Managers often earn about 15 to 25
percent more than those they directly supervise, although there are
cases where some employees are paid more than the manager who
supervises them.
In addition, engineering, science, and data processing managers,
especially those at higher levels, often are provided more fringe bene­
fits than non-managerial workers in their organizations. Higher level
managers often are provided with expense accounts, stock option
plans, and bonuses.

for efficient and economical performance. They design industrial
machinery and equipment for manufacturing goods; design defense
and weapons systems for the Armed Forces; and design, plan, and
supervise the construction of buildings, highways, and rapid transit
systems. They also design and develop consumer products and sys­
tems 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 the
general way it needs to work; design and test components; fit them
together in an integrated plan; and evaluate the design’s overall
effectiveness, cost, reliability, and safety. This process applies to
products as different as computers, gas turbines, generators, heli­
copters, 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 manufactured
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 installation or
use. (See the statements on engineering, science, and data processing
managers and manufacturers’ and wholesale sales representatives
elsewhere in the Handbook.)
Most engineers specialize; more than 25 major specialties are rec­
ognized by professional societies. Within the major branches are
numerous 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 statements on 10 branches of the profession—
aerospace; chemical; civil; electrical and electronics; industrial;
mechanical; metallurgical, ceramic, and materials; mining; nuclear;
and petroleum engineering.
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

More than one-fourth of all engineers are
electrical engineers.

Nature of the Work
Engineers apply the theories and principles of science and mathemat­

distribution fields. Because there are many separate problems to solve
in a large engineering project, such as a mission to Mars, engineers in
one field often work closely with specialists in scientific, other engi­
neering, and business occupations.
Engineers often use computers to solve mathematical equations
which describe how a machine, structure, or system operates. Many
engineers also use computer-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 responsible 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 considerable
stress.
Employment
In 1990, engineers held 1,519,000 jobs. Over one-half of all engineer­
ing jobs were located in manufacturing industries—mostly in electri­
cal and electronic equipment, aircraft and parts, machinery, scientific
instruments, chemicals, motor vehicles, fabricated metal products,
and primary metals industries. In 1990, 739,000 jobs were in non­
manufacturing industries, primarily in engineering and architectural
services and business and management consulting services, where
firms designed construction projects or did other engineering work on
a contract basis for organizations in other parts of the economy. Engi­
neers also worked in the communications, utilities, and construction
industries.
Federal, State, and local governments employed about 201,000
engineers. About 60 percent were in the Federal Government, mainly
in the Departments of Defense, Transportation, Agriculture, Interior,
and Energy, and in the National Aeronautics and Space Administra­

tion. Most engineers in State and local government agencies worked
in highway and public works departments. Some engineers are selfemployed 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 statements
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 offer
degrees in engineering technology, which are offered as either 2- or
4-year programs. These programs prepare students for practical
design and production work rather than for jobs that require more
theoretical, scientific and mathematical knowledge. Graduates of 4year technology programs may get jobs similar to those obtained by
graduates with a bachelor’s degree in engineering. However, some
employers regard them as having skills between those of a technician
and an engineer.
Graduate training is essential for engineering faculty positions but
is not required for the majority of entry level engineering jobs. Many
engineers obtain a master’s degree to learn new technology, to broad­
en their education, and to enhance promotion opportunities.
Nearly 260 colleges and universities offer a bachelor’s degree in
engineering, and nearly 100 colleges offer a bachelor’s degree in engi­
neering technology. Although 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 industry, while others are more theoretical and are better for stu­
dents preparing to take graduate work. Therefore, students should
investigate curriculums carefully before selecting a college. Admis­
sions requirements for undergraduate engineering schools include
courses in advanced high school mathematics and the physical sci­
ences.
In a typical 4-year college curriculum, the first 2 years are spent
studying basic sciences (mathematics, physics, and chemistry), intro­
ductory engineering, and the humanities, 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 aerodynamics, analytical mechanics, flight
vehicle design, trajectory dynamics, and aerospace propulsion sys­
tems. Some programs offer a general engineering curriculum; stu­
dents 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 education
and the engineering school automatically admits students for their
last 2 years. In addition, a few engineering schools have arrange­
ments 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 experi­
ence 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
offer their services to the public. In 1990, nearly 500,000 engineers
were registered. Registration generally requires a degree from an
engineering 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 eventu­
ally become engineering managers or enter other managerial, man­
agement support, or sales jobs. (See the statements under executive,
administrative, and managerial occupations; under sales occupations;
and on computer systems analysts elsewhere in the Handbook.) Some
engineers obtain graduate degrees in 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 addition,
engineers should be able to express themselves well—both orally and
in writing.
Job Outlook
Employment opportunities in engineering have been good for a num­
ber of years. They are expected to continue to be good through the
year 2005 because employment is expected to increase faster than the
average for all occupations while the number of degrees granted in
engineering is not likely to increase much beyond present levels.
Employers will need more engineers as they increase investment in
plant and equipment in order to expand output of goods and services
and to further increase productivity. In addition, competitive pres­
sures 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 pollu­
tion 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, at least through the early 1990s, because the
total college-age population is projected to decline. Furthermore, the
proportion of students interested in engineering careers has declined
as prospects for college graduates in other fields have improved.
One sign that engineering graduates have good prospects is that
they have starting salaries substantially higher than those of most
other graduates with bachelor’s degrees. Another is that engineering
students, who earned less than 9 percent of all bachelor’s degrees in
1990, received more than 40 percent of the job offers to bachelor’s
degree graduates, according to the College Placement Council. In
addition, most have received at least one job offer before graduation,
which has not been the case for many other graduates.
Although employers generally prefer engineering graduates, there
should continue to be opportunities in engineering for qualified grad­
uates in science and other related fields.
Only a relatively small proportion of engineers leave the profes­
sion each year. Despite this, most job openings will arise from
replacement needs. A greater proportion of replacement openings is
created by engineers who transfer to management, sales, or other pro­
fessional specialty occupations than by those who leave the labor
force.
Most industries are less likely to lay off engineers than other work­
ers. Many engineers work on long-term research and development
projects or in other activities which may continue even during reces­
sions. However, in industries such as electronics and aerospace, large
government cutbacks in defense or research and development may
result in layoffs for engineers.
New computer-aided design systems enable engineers to produce
or modify designs much more rapidly than previously. This increased
productivity might have resulted in fewer engineering jobs, but this
has not happened. Instead, engineers have used these systems to
improve the design process. They now produce and analyze many

https://fraser.stlouisfed.org

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 throughout
their careers because much of their value to their employer depends
on their knowledge of the latest technology. The pace of technologi­
cal change varies by engineering specialty and industry. Engineers in
high-technology areas such as advanced electronics or aerospace may
find that their knowledge becomes obsolete rapidly. Even those who
continue their education are vulnerable to obsolescence if the particu­
lar 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 specialty
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 state­
ments.)
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 $31,900 a year
in private industry in 1990; those with a master’s degree and no expe­
rience, $36,200 a year; and those with a Ph.D., $50,400. Starting
salaries for those with the bachelor’s degree vary by branch, as
shown in the following tabulation.

Nature of the Work
Aerospace engineers design, develop, test, and help manufacture
commercial and military aircraft, missiles, and spacecraft. They
develop new technologies in commercial aviation, defense systems,
and space exploration, often specializing in areas like structural
design, 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, heli­
copters, 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 73,000 jobs in 1990. Two-thirds
were in the aircraft and parts and guided missile and space vehicle
manufacturing industries. Federal Government agencies, primarily
the Department of Defense and the National Aeronautics and Space
Administration, provided over 1 out of 10 jobs. Business and engi­
neering consulting firms 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
Employment of aerospace engineers is expected to grow about as fast
as the average for all occupations through the year 2005. Although
Defense Department expenditures for military aircraft, missiles, and
other aerospace systems are expected to decline, faster growth is
expected in the civilian sector. Much of the present fleet of airliners
will be replaced with quieter and more fuel-efficient aircraft, and
there will be increased demand for spacecraft, helicopters, and busi­
ness aircraft. Future growth of aerospace engineer employment could
be limited because a higher proportion of engineers in aerospace
manufacturing may be materials, mechanical, or electrical engineers.
Most job openings will result from the need to replace aerospace
engineers who transfer to other occupations or leave the labor force.

Chemical Engineers
(D.O.T. 008.061 except .030)

Nature of the Work
Chemical engineers apply the principles of chemistry and engineer­
ing to solve problems. Many work in the production of chemicals
and chemical products. They design equipment and develop process­
es for manufacturing chemicals in chemical plants, plan and test
methods of manufacturing the products, and supervise production.
Chemical engineers also work in industries other than chemical man­
ufacturing such as electronics or aircraft manufacturing. Because the
knowledge and duties of chemical engineers cut across many fields,
they apply principles of chemistry, physics, mathematics, and
mechanical and electrical engineering in their work. They frequently
specialize in a particular operation such as oxidation or polymeriza­
tion. Others specialize in a particular area such as pollution control
or the production of a specific product like automotive plastics or
chlorine bleach.
Employment
Chemical engineers held over 48,000 jobs in 1990. Seventy percent
were in manufacturing industries, primarily in the chemical,
petroleum refining, and related industries. Most of the rest worked for
engineering services or consulting firms that design chemical plants
or do other work on a contract basis, or worked for government agen­
cies or as independent consultants.
Job Outlook
Employment of chemical engineers is expected to grow more slowly
than the average for all occupations through the year 2005. This
reflects little, if any, growth in the chemical manufacturing industry,
where many chemical engineers are employed. Most openings, how­
ever, will result from the need to replace chemical engineers who
transfer to other occupations or leave the labor force.

Civil Engineers
(D.O.T. 005.061, .167-014 and -018; and 019.167-018)

Nature of the Work
Civil engineers, who work in the oldest branch of engineering, design
and supervise the construction of roads, airports, tunnels, bridges,
water supply and sewage systems, and buildings. Major specialties
within civil engineering are structural, water resources, environmen­
tal, construction, transportation, and geotechnical engineering.
Many civil engineers hold supervisory or administrative positions,
ranging from supervisor of a construction site to city engineer. Others
may work in design, construction, research, and teaching.
Employment
Civil engineers held about 198,000 jobs in 1990. 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 con­
struction industry, public utilities, transportation, and manufacturing
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 faster than the
average for all occupations through the year 2005. Most job open­
ings, however, will result from the need to replace civil engineers
who transfer to other occupations or leave the labor force.
A growing population and an expanding economy will create
opportunities for more civil engineers to design and construct higher
capacity transportation, water supply, and pollution control systems,
large buildings, and other structures. More civil engineers also will be
needed to repair or replace existing roads, bridges, and other public
structures.
Because construction and related industries—including those pro­
viding design services—employ many civil engineers, employment
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, -062, 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 equipment
used by electric utilities, and electric motors, machinery controls, and
lighting and wiring in buildings, automobiles, and aircraft. 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 distri­
bution; communications; computer electronics; and electrical
equipment manufacturing—or a subdivision of these areas—industri­
al robot control systems or aviation electronics, for example. Electri­
cal and electronics engineers design new products, write performance
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 426,000 jobs in 1990,
making it the largest branch of engineering. Most jobs were in firms
that manufacture electrical and electronic equipment, business
machines, professional and scientific equipment, and aircraft and
parts. Computer and data processing services firms, engineering and
business consulting firms, public utilities, and government agencies
accounted for most of the remaining jobs.

Civil engineers review the progress of construction projects.

Job Outlook
Employment opportunities for electrical and electronics engineers are
expected to be good through the year 2005 because employment is
expected to increase faster than the average for all occupations. The
majority of job openings will result from the need to replace electri­
cal and electronics engineers who transfer to other occupations or
leave the labor force.
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
computers, robots, and other types of automation should create addi­
tional jobs.
Since many electrical engineering jobs are defense related, expect­
ed cutbacks in defense spending could result in layoffs of electrical

openings, however, will result 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. Jobs also will be created as firms seek to
reduce costs and increase productivity through scientific management
and safety engineering.

-062, and -066, and .187)

Nature of the Work
Industrial engineers determine the most effective ways for an organi­
zation to use the basic factors of production—people, machines,
materials, information, and energy. They are the bridge between man­
agement and operations. They are more concerned with increasing
productivity through the management of people and methods of busi­
ness organization than are engineers in other specialties, who general­
ly work more with products or processes.
To solve organizational, production, and related problems most
efficiently, industrial engineers design data processing systems and
use mathematical analysis methods such as operations research. They
develop management control systems to aid in financial planning and
cost analysis, design production planning and control systems to
coordinate activities and control 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 taxes. They
also develop wage and salary administration systems and job evalua­
tion programs. Many industrial engineers move into management
positions because the work is closely related.

(D.O.T. 007.061, .161-022, -034, and -038, and .267)

Nature of the Work
Mechanical engineers are concerned with the production, transmis­
sion, and use of mechanical power and heat. They design and develop
power-producing machines such as internal combustion engines,
steam and gas turbines, and jet and rocket engines. They also design
and develop power-using machines such as refrigeration and air-con­
ditioning equipment, robots, machine tools, materials handling sys­
tems, and industrial production equipment.
The work of mechanical engineers varies by industry and function.
Specialties include, among others, applied mechanics, design engi­
neering, heat transfer, powerplant engineering, pressure vessels and
piping, and underwater technology. Mechanical engineers design
tools needed by other engineers for their work.
Mechanical engineering is the broadest engineering discipline,
extending across many interdependent specialties. Some mechanical
engineers work in production operations, maintenance, and technical
sales. Many are administrators or managers.
Employment
Mechanical engineers held about 233,000 jobs in 1990. Over 3 out of
5 jobs were in manufacturing—of these, most were in the machinery,

Employment
Industrial engineers held about 135,000 jobs in 1990; about 75 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 industries than other engineers.
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. Most job

their processing. Ceramic engineers work on products as diverse as
glassware, semiconductors, automobile and aircraft engine compo­
nents, fiber-optic phone lines, tile, and electric powerline 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” aircraft.

Job Outlook
Employment of mechanical engineers is expected to increase about as
fast as the average for all occupations through the year 2005 as the
demand for machinery and machine tools grows and industrial
machinery and processes become increasingly complex. Despite this
expected employment growth, however, most job openings will result
from the need to replace mechanical engineers who transfer to other
occupations or leave the labor force.
Since many mechanical engineering jobs are in defense related
industries, reductions in defense spending could result in layoffs in
these industries.

Metallurgical, Ceramic,
and Materials Engineers
(D.O.T. 006.061; 011.061 and .261-018; and 019.061-014)

Nature of the Work
Metallurgical, ceramic, and materials engineers develop new types of
metals, 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 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 con­
verting refined metals into final products. Mechanical metallurgists
develop and improve metalworking processes such as casting, forg­
ing, rolling, and drawing.
Ceramic engineers develop new ceramic materials and methods for
making ceramic materials into useful products. Ceramics include all
nonmetallic, inorganic materials which require high temperatures in

https://fraser.stlouisfed.org
Federal Reserve Bank of St. Louis

Employment
Metallurgical, ceramic, and materials engineers held over 18,000 jobs
in 1990. About one-quarter worked in metal-producing industries.
They also worked in industries that manufacture aircraft and parts,
machinery, and electrical equipment, and in business and engineering
consulting firms and government agencies.
Job Outlook
Employment of metallurgical, ceramic, and materials engineers is
expected to grow about as fast as the average for all occupations
through the year 2005. Most job openings, however, will result from
the need to replace engineers who transfer to other occupations or
leave the labor force.
More metallurgical, ceramic, and materials engineers will be need­
ed by the metalworking and other industries to develop new metals,
alloys, and materials, as well as to develop new applications for exist­
ing materials. As the supply of high-grade ores diminishes, more met­
allurgical engineers will be required to develop new ways of
recycling solid waste materials and processing low-grade ores now
regarded as unprofitable to mine.
More ceramic and materials engineers will be needed to develop
improved materials and products, for example, ceramic automobile
engines, which are more fuel efficient than metal engines.

Mining Engineers
(D.O.T. 010.061 except -018)

Nature of the Work

ing industries to use. They design open pit and underground mines,
supervise the construction of mine shafts and tunnels in underground

operations, and devise methods for transporting minerals to process­
ing plants. Mining engineers are responsible for the safe, economical,
and environmentally sound operation of mines. Some mining engi­
neers work with geologists and metallurgical engineers to locate and
appraise new ore deposits. Others develop new mining equipment or
direct mineral processing operations 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.

Sources of Additional Information

Employment
Mining enginers held about 4,200 jobs in 1990. Over half worked in
the mining industry. Other jobs were located in engineering consult­
ing firms, government agencies, or in manufacturing industries.
Mining engineers are usually employed at the location of mineral
deposits, often near small communities. However, those in research
and development, management, consulting, or sales often are located
in metropolitan areas.
Job Outlook
Little change is expected in the employment of mining engineers
through the year 2005 due to expected low growth in demand for
coal, metals, and other minerals. Most job openings will result from
the need to replace the large proportion of mining engineers who
transfer to other occupations each year.
In the mid-1980’s, mining engineers experienced poor employment
opportunities because low prices for oil and metals reduced prof­
itability in coal, metal, and other mining. However, the prices of these
commodities, metals in particular, have increased to a level sufficient
to increase output and employment opportunities. Increased demand
for coal and, consequently, for mining engineers in the coal industry
will depend, to a great extent, on the availability and price of other
energy sources such as petroleum, natural gas, and nuclear energy as
well as the price of coal in other countries. More technologically
advanced mining systems and further enforcement of mine health and
safety regulations may also increase the need for mining engineers.
As easily mined deposits are depleted, engineers must devise more
efficient methods for mining and processing low-grade ores. Employ­
ment opportunities also may rise as new alloys and new uses for min­
erals and metals increase the demand for less widely used ores.

Nuclear Engineers
(D.O.T. 008.061-030; 015.061, .067, .137, and .167)

Nature of the Work
Nuclear engineers conduct research on nuclear energy and radiation.
They design, develop, monitor, and operate nuclear power plants
used to generate electricity and power Navy ships. For example, they
may work on the nuclear fuel cycle—the production, handling, and
use of nuclear fuel and the safe disposal of waste produced 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 diagnose and treat
medical problems.
Employment
Nuclear engineers held about 18,000 jobs in 1990; one-fifth were in
the Federal Government. Nearly half of all federally employed nucle­
ar 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 equip­
ment.
Job Outlook
Employment of nuclear engineers is expected to change little through
the year 2005. Almost all job openings will result from the need to
replace nuclear engineers who retire or leave the occupation. Despite
the expected absence of growth, there are expected to be good oppor­
tunities for nuclear engineers because the number of new graduates
with degrees in nuclear engineering is small and has been declining

recently. Some with degrees in physics may also find employment as
nuclear engineers.
Because of concerns over the safety of nuclear power, few or no
nuclear powerplants are likely to be started before the year 2005.
However, nuclear engineers will be needed to operate plants present­
ly under construction. In addition, nuclear engineers will be needed to
work in defense-related areas and to improve and enforce safety stan­
dards.

Job Outlook
Employment of petroleum engineers is expected to change little
through the year 2005. Because of low oil prices in the 1980s, domes­
tic petroleum companies sharply curtailed exploration and production
activities, resulting in poor employment opportunities for petroleum
engineering graduates. In the long run, however, it appears likely that
the price of oil will increase to a level sufficient to increase explo­
ration and production, which would imply excellent employment
prospects for petroleum engineers since the number of degrees
recently granted in petroleum engineering has been very low. Despite
this expected employment growth, most job openings will result from
the need to replace petroleum engineers who transfer to other occupa­
tions or leave the labor force.

Petroleum Engineers

(See introductory part of this section for information on training
requirements and earnings.)

(D.O.T. 010.061 except -014 and -026, .161-010, and .167-010 and -014)

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,
petroleum engineers work to achieve the maximum profitable recov­
ery from the reservoir by determining and developing the most effi­
cient production methods.
Since 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 water,
chemicals, or steam into a reservior to force more of the oil out, and
horizontal drilling or fracturing to connect more of a reservior to a
well. Since even the best methods in use today recover only about
half the oil in a reservoir, petroleum engineers work to find ways to
increase this proportion.
Employment
Petroleum engineers held over 17,000 jobs in 1990, mostly in the
petroleum 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 consultants.
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 Califor­
nia, including offshore sites. Also, many American petroleum engi­
neers work overseas in oil-producing countries.

Agricultural Scientists
(D.O.T. 040.061-010, -014, -018, -038, -042, and -058; 041.061-014, -018,
-046, and -082; and 041.081)

Nature of the Work
The work done by agricultural scientists has played an important part
in the Nation’s sharply rising agricultural productivity. Agricultural
scientists study farm crops and animals and develop ways of improv­
ing 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 applying to
agriculture the advances in knowledge brought about by biotechnology.
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 chemi­
cals, 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 area of specialization in which an agricultural
scientist concentrates, the nature of the work performed varies.
Food science. Food scientists or technologists are usually employed
in the food processing industry 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 develop new or better ways of preserving, process­
ing, packaging, storing, and delivering foods. Some engage in basic
research, discovering 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 or
sugar. Many food technologists work in product development. Others
enforce government regulations, inspecting food processing areas and
ensuring that sanitation, safety, quality, and waste management stan­
dards are met.
Plant science. Another important area of agricultural science is plant
science, which includes the disciplines of agronomy, crop science,
and soil science. These scientists study plants and soils, helping pro­
ducers of food, feed, and fiber crops to continue to feed a growing
population while conserving natural resources. Agronomists and crop
scientists not only help increase productivity, but also study ways to
improve the nutritional value of crops and the quality of seed. Some
11

crop scientists study the breeding, physiology, and management of
crops and use genetic engineering to develop crops which are resis­
tant to insects 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. Some soil scientists 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.
Animal science. Animal scientists work to develop better and more
efficient ways of producing and processing meat, poultry, eggs, and
milk. Dairy scientists, poultry scientists, animal breeders, and other
related 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 prop­
erly upgrade animal housing facilities, lower mortality rates, or
increase milk or egg production.
Working Conditions
Agricultural scientists generally work regular hours in offices and
laboratories. Some spend much time outdoors conducting research on
farms or agricultural research stations.
Employment
Agricultural scientists held about 25,000 jobs in 1990. In addition,
several thousand persons held agricultural science faculty positions in

colleges and universities. (See the statement on college and university
faculty elsewhere in the Handbook.)
Over two-fifths of all nonfaculty agricultural scientists work for
Federal, State, or local governments. Over 3 out of 10 worked for the
Federal Government in 1990, mostly in the Department of Agricul­
ture. 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,
pharmaceutical companies, wholesale distributors, and food products
companies. About 3,000 agricultural scientists were self-employed in
1990, mainly as consultants.
Training, Other Qualifications, and Advancement
Training requirements for agricultural scientists depend on the spe­
cialty and the type of work performed. A bachelor’s degree in agri­
cultural science is sufficient for some jobs in applied research or in
assisting in basic research, while a master’s or doctoral degree is
required for basic research. A Ph.D. degree in agricultural science is
usually needed for college teaching and for advancement to adminis­
trative research positions. Degrees in related sciences such as biolo­
gy, chemistry, or physics or in related engineering specialties also
may be acceptable for some agricultural science jobs.
All States have at least one land-grant college which offers agricul­
tural 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 undergrad­
uate agricultural science curriculum includes communications, eco­
nomics, business, and physical and life sciences courses, in addition
to technical agricultural science courses. Advanced degree programs
include classroom 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 under­
standing 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 agriculturerelated activities.
Job Outlook
Employment opportunities for agricultural scientists are expected to
be good through the year 2005 because enrollments in agricultural
science curriculums have dropped considerably over the past few
years and because employment is expected to grow faster than the
average for all occupations. Although jobs should be available in
most major subfields of agricultural science, animal and plant scien­
tists with a background in molecular biology, microbiology, genetics,
or biotechnology, soil scientists with an interest in the environment,
and food technologists may experience the best opportunities. In
addition to jobs arising from growth in demand for agricultural scien­
tists, many openings will occur as workers transfer to other occupa­
tions or leave the labor force.
Unlike private industry, employment in Federal agencies is not
expected to grow much because of budget restraints.
Employment opportunities as an agricultural scientist are more
limited for those with only a bachelor’s degree. However, a bache­
lor’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 manufacturers, retailers or wholesalers,
and farm credit institutions or for occupations such as farmer or farm
manager, cooperative extension service agent, agricultural products
inspector, technician, landscape architect, or purchasing or sales
agent for agricultural commodities or farm supplies. Many agricultur­
al scientists with a bachelor’s degree may also find work in applied
research and product development.
Earnings
According to the College Placement Council, beginning salary offers
in 1990 for graduates with a bachelor’s degree in animal science

averaged $19,719 a year, and for graduates in plant science, $21,176.
Average Federal salaries for employees in certain agricultural sci­
ence specialties in 1991 were as follows:
Animal science, $48,827; agronomy, $42,234; soil science,
$39,216; horticulture, $40,520; entomology, $49,475.
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 specialties
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.

Biological Scientists

-074, and -082)

Nature of the Work
Biological scientists study living organisms and their relationship to
their environment. Most specialize in some area of biology such as
ornithology (the study of birds) or microbiology (the study of micro­
scopic organisms).
About two-fifths of all biological 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. Biological scientists may work in laborato­
ries and use laboratory animals or greenhouse plants, electron micro­
scopes, computers, electronic instruments, or a wide variety of other
equipment to conduct their research. A good deal of research, howev­
er, is performed outside of laboratories. For example, a botanist may
do research in tropical rain forests to see what plants grow there, or an
ecologist may study how a forest area recovers after a fire.
Other biological 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
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 state­
ment on manufacturers’ and wholesale sales representatives else­
where in the Handbook.)
Advances in basic biological knowledge, especially at the genetic
level, have given rise to the new field of biotechnology. Biologists

using this rapidly developing technology recombine the genetic
material of animals or plants, making organisms more productive or
disease resistant. The first application of this technology has been in
the medical and pharmaceutical area. For example, the human gene
that codes for the production of insulin has been inserted into bacte­
ria, causing them to produce human insulin. This insulin, used by
diabetics, is much purer than insulin from animals, the only previous
source. Many other 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, including commercial applications in agricul­
ture 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
reactions involved in metabolism, reproduction, growth, and heredi­
ty. Much of the work in biotechnology is done by biochemists
because this technology involves understanding the complex chem­
istry of life.
Botanists study plants and their environment. Some study all
aspects 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
microscopic organisms such as bacteria, algae, and fungi. Medical
microbiologists study the relationship between organisms and dis­
ease or the effect of antibiotics on microorganisms. Other microbiol­
ogists may specialize in environmental, food, agricultural, or
industrial microbiology, virology (the study of viruses), or immunol­
ogy (the study of mechanisms that fight infections). Many microbi­
ologists are using biotechnology to advance knowledge of cell
reproduction 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 move­
ment, or in the physiology of a certain area or system of the body.
Zoologists study animals—their origin, behavior, diseases, and
life processes. Some experiments are with live animals in controlled
or natural surroundings while others involve dissecting dead animals
to study their structure. Zoologists are usually identified by the ani­
mal group studied—ornithologists (birds), mammalogists (mam­
mals), herpetologists (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 on
organisms.
Agricultural scientists, who may also be classified as biological
scientists, are included in a separate statement elsewhere in the
Handbook.
Working Conditions
Biological scientists generally work regular hours in offices, labora­
tories, or classrooms and usually are not exposed to unsafe or
unhealthy conditions. However, some work with dangerous organ­
isms or toxic substances in the laboratory. They could be exposed if
safety procedures are not followed. Many biological scientists such
as botanists, ecologists, and zoologists take field trips which involve
strenuous physical activity and primitive living conditions.
13

Employment
Biological scientists held about 62,000 jobs in 1990. In addition,
about half as many held biology faculty positions in colleges and uni­
versities. (See the statement on college and university faculty else­
where in the Handbook.)
About 40 percent of nonfaculty biological scientists were
employed by Federal, State, and local governments. Federal biologi­
cal scientists worked mainly in the Departments of Agriculture, Inte­
rior, and Defense, and in the National Institutes of Health. Most of
the rest worked in the pharmaceutical industry, hospitals, offices of
physicians, or research and testing laboratories. A few were selfemployed.
Training, Other Qualifications, and Advancement
The Ph.D. degree generally is required for college teaching, indepen­
dent research, and for advancement to administrative 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 inspec­
tion, 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 laboratory environment on their own pro­
jects, but this is unusual. Some may work as research assistants. Oth­
ers become biological technicians, medical laboratory technologists
or, with courses in education, high school biology teachers. (See the
statements on clinical laboratory technologists and technicians, sci­
ence technicians, 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
advanced degrees often emphasize a subfield such as microbiology or
botany but not all universities offer all curriculums. Advanced degree
programs include classroom and field work, laboratory research, and
a thesis or dissertation. Biological scientists who have advanced
degrees usually begin in research or teaching. With experience, they
may become managers or administrators within biology; others leave
biology for nontechnical managerial, administrative, 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 areas must
have physical stamina.
Job Outlook
Employment of biological scientists is expected to increase faster
than the average for all occupations through the year 2005. Most
growth will be in private industry. Biological scientists will continue
to conduct genetic and biotechnical 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, especially for those with a bachelor’s or a master’s degree.
More biological scientists will be needed to determine the environ­
mental impact of industry and government actions and to correct past
environmental problems. Anticipated increases in health-related
research should also result in growth. Because of budget cuts,
employment of biologists is expected to grow slowly in the Federal
Government. In addition to jobs arising from growth in demand for
biologists, openings will occur as biological scientists transfer to
other occupations or leave the labor force. Because a large number of
biological science college and university faculty are expected to retire
in the next 10 years, many more positions will open up in academia.
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. However,
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 scientists are less likely to lose their jobs during reces­
sions than those in many other occupations since most are employed
on long-term research projects or in agricultural research. 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
$31,300 in 1990; the middle 50 percent earned between $20,700 and
$45,200. Ten percent earned less than $13,100, and 10 percent earned
over $55,600. According to the College Placement Council, begin­
ning salary offers in private industry in 1990 averaged $21,800 a year
for bachelor’s degree recipients in biological science.
In the Federal Government in 1991, general biological scientists
earned an average salary of $41,754; microbiologists averaged
$44,518; ecologists, $42,795; physiologists, $50,097; and geneticists,
$50,949.
Related Occupations
Many other occupations deal with living organisms and require a
level of training similar to that of biological scientists. These include
the conservation occupations of forester, range manager, and soil con­
servationist; 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 scientists, medical doctors, dentists, and veterinarians.

Foresters and Conservation Scientists
(D.O.T. 040.061-030, -034, -046, -050, -054, -062; 049.127)

Nature of the Work
Forests and rangelands serve a variety of needs: They supply wood
products, livestock forage, minerals, and water; serve as sites for
recreational activities; and provide habitats for wildlife. Foresters and
conservation scientists manage, develop, and help protect these and
other natural resources.
Foresters manage timberland, which involves a variety of duties.
Those working in private industry may be responsible for procuring
timber from private landowners. To do this, foresters make contact
with 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 tim­
ber’s worth, negotiate the purchase of timber, and draw up a contract
for procurement. Next, they subcontract with loggers or pulpwood
cutters to remove the trees, aid in road layout, and maintain close
contact with the subcontractor’s workers and the landowner to ensure
that the work is performed to 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 entire process, foresters consider not only the eco­
nomics of the purchase but the environmental impact on natural
resources. They determine how best to preserve wildlife habitats,
creek beds, water quality, and soil stability. They also comply with
environmental regulations.
Foresters also supervise the planting and growing of new trees.
They choose and prepare the site, using controlled burning, bulldoz­
ers, or herbicides to clear weeds, brush, and logging debris. They
advise on the type, number, and placement of trees to be planted.
Foresters monitor the trees to ensure healthy growth and to determine
the best time for harvesting. If foresters detect signs of disease or
harmful insects, they decide on the best course of treatment to pre­
vent contamination or infestation of healthy trees.
Foresters who work for State and Federal governments manage
public parks and forests. 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 incre­
ment borers and bark gauges measure the growth of trees. 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. Comput­
ers 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 Western
States and Alaska. They contain many natural resources, including
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 animals 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 recreation.
Soil conservationists provide technical assistance to farmers,
ranchers, and others concerned with the conservation of soil, water,
and related natural resources. They develop programs that are
designed to get the most productive use of land without damaging it.
Soil conservationists do most of their work in the field. Conservation­
ists visit areas with erosion problems, find the source of the problem,
and help landowners and managers develop management practices to
combat it.

https://fraser.stlouisfed.org
Federal Reserve Bank of St. Louis

Foresters and conservation scientists often specialize in one area of
work, such as forest resource management, urban forestry, wood
technology, or forest economics.
Working Conditions
Working conditions for foresters and conservation scientists vary
considerably. Their image as solitary horseback riders singlehandedly
protecting large areas of land far from civilization no longer holds
true. Modem foresters and conservation scientists spend a great deal
of time working with people. They deal regularly with landowners,
loggers, forestry technicians and aides, farmers, ranchers, govern­
ment 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
foresters and conservation scientists often work outdoors in all kinds
of weather, sometimes in isolated areas. To get to these areas, they
use airplanes, helicopters, four-wheel drive vehicles, and horses. It
may be necessary for some foresters to walk long distances through
densely wooded land in order 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 29,000 jobs in 1990.
About 44 percent of the salaried workers were in the Federal Govern­
ment, primarily in the Department of Agriculture’s Forest Service and
Soil Conservation Service and in the Department of Interior’s Bureau
of Land Management. The Forest Service alone employed over 5,000
foresters and 400 range conservationists in 1990. Another 26 percent
worked for State governments, and 7 percent worked for local gov­
ernments. 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 con­
sultants, primarily for private landowners, but also for State and Fed­
eral 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 locat-

ed, and where most of the lumber and pulpwood-producing forests
are located. Range managers work almost entirely in the Western
States, where most of the rangeland is located. Soil conservationis
ts, 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
occasionally be substituted for a 4-year forestry degree, but keen job
competition makes this difficult.
Some States have licensing or registration requirements which a
forester must meet in order to acquire the title “professional
forester.” Becoming licensed or registered usually requires a 4-year
degree in forestry, a minimum period of training time, and passing a
registration exam.
Foresters who wish to perform specialized research or teach
should have an advanced degree, preferably a Ph.D.
In 1991, 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, com­
munications skills, and computer science, as well as technical
forestry subjects. Courses in forest economics and business admin­
istration supplement the student’s scientific and technical knowl­
edge. Many colleges 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 conserva­
tion work.
A bachelor’s degree in range management or range science is the
usual minimum educational requirement for range managers, while
graduate degrees generally are required for teaching and research
positions. In 1990, 35 colleges and universities offered degrees in
range management or range science. A number of other schools
offered some courses in range management. Specialized range man­
agement courses combine plant, animal, and soil sciences with prin­
ciples of ecology and resource management. Desirable electives
include economics, forestry, hydrology, agronomy, 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
resources 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 must
enjoy working outdoors, be physically hardy, and be willing to
move to where the jobs are. They must also be able to work well
with people and have good communications skills. Decisiveness,
firmness, and tact are important in disputes involving rights and
uses of land and other natural resources.
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
positions. 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 region­
al 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 train­
ing. They are then introduced to contract writing, timber harvesting,
and decisionmaking. Many foresters work their way up to top man­
agerial positions within their companies. Foresters in management
usually leave the fieldwork behind, spending more of their time in
an office, doing paperwork and supervising others.
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 due to budgetary constraints in the Federal Government,
where employment is concentrated. However, an expected wave of
retirements in the Federal Government should create many job open­
ings for foresters. On the other hand, jobs for soil conservationists
should continue to be competitive in the Federal Government. The
number of qualified graduates usually exceeds the available positions
because the educational requirements for soil conservationists are less
specific than those for foresters or range conservationists. More
foresters and range managers should be needed in private industry to
improve forest, logging, and range management practices and
increase output and profitability. Also, State governments and private
owners of timberland may employ more foresters due to increased
interest in environmental protection and land management.
Regardless of the outlook, certain areas of the country offer greater
job opportunities for foresters and range conservationists than other
regions. Employment for range conservationists is concentrated in the
West and Midwest, while most forestry-related employment is in the
South and West. Urban forestry is emerging as a fast-growing field,
particularly in the Northeast and in major population centers of the
country. Because of public interest in environmental issues, foresters
are increasingly needed to perform environmental impact studies in
urban areas, and to help regional planning commissions make land
use decisions.
Earnings
Most graduates entering the Federal Government as foresters, range
managers, or soil conservationists with a bachelor’s degree started at
$16,973 or $21,023 a year, in 1991, depending on academic achieve­
ment. Those with a master’s degree could start at $21,023 or $25,717.
Holders of doctorates could start at $31,116 or, in research positions,
at $37,294. In 1991, the average Federal salary for foresters was
$38,617; for range conservationists, $34,082; for soil conservation­
ists, $35,835; and for forest products technologists, $53,090.
In private industry, starting salaries for students with a bachelor’s
degree were comparable to starting salaries in the Federal Govern­
ment, while starting salaries in State and local governments were
generally lower.
Most foresters and conservation scientists work for Federal, State,
and local governments and large private firms, which generally offer
more generous fringe benefits—for example, pension and retirement
plans, health and life insurance, and paid vacations—than smaller
firms.
Related Occupations
Foresters and conservation scientists are not the only workers con­
cerned with managing, developing, and protecting natural resources.
Other workers with similar responsibilities include agricultural scien­
tists, agricultural engineers, biological scientists, farmers, farm man­
agers, forest fire officers, ranchers, ranch managers, soil scientists
and soil conservation technicians, wildlife managers, and environ­
mental scientists.

Chemists
(D.O.T. 022.061-010, -014, and .137-010)

Nature of the Work
Chemists search for and put to practical use new knowledge about
chemicals. Although chemicals are often thought of as artificial or
toxic substances, all physical things, both natural and manmade, are
composed of chemicals. Chemists have developed a tremendous vari­
ety 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 methods. Research on the chemistry of living
things provides the basis for advances in medicine, agriculture, and
other areas.
Many chemists work in research and development. Much research
is performed in laboratories, but research chemists also work in
offices when they do theoretical research or plan, record, and report
on their research. Some chemical research laboratories resemble high
school chemical labs, but others are large and may incorporate proto­
type chemical manufacturing facilities as well as advanced equip­
ment. Chemists may also do some of their research in a chemical
plant or outdoors—while gathering samples of pollutants, for example.
In basic research, chemists investigate the properties, composition,
and structure of matter and the laws that govern the combination of
elements and reactions of substances. In applied research and devel­
opment, they create new products or improve existing ones, often
using knowledge gained from basic research. For example, synthetic
rubber and plastics resulted from research on small molecules uniting
to form large ones (polymerization).
Chemists also work in production and inspection in chemical man­
ufacturing 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 ensure proper
product yield, and test samples to ensure they meet industry and gov­
ernment standards. Chemists also record and report 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 devel­
op analytical techniques. They also identify the presence of chemical
pollutants in air, water, and soil. Organic chemists study the chem­
istry of the vast number of carbon compounds. 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 investigate how chemical reactions work.
Their research may result in new and better energy sources.
Biochemists, whose work encompasses both biology and chemistry,
are included under biological scientists elsewhere in the Handbook.
Working Conditions
Chemists usually work regular hours in offices and laboratories.
Some 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 83,000 jobs in 1990. The majority of chemists are
employed in manufacturing firms—mostly in the chemical manufac­
turing industry, which includes firms that produce plastics materials
and synthetics, drugs, soap and cleaners, paints, industrial organic
chemicals, and other miscellaneous chemical products. Chemists also
work for State and local governments, primarily in health and agricul­
ture, and for Federal agencies, chiefly in the Departments of Defense,
Health and Human Services, and Agriculture. 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.)

https://fraser.stlouisfed.org
Federal Reserve Bank of St. Louis

The knowledge gainedfrom basic chemical research often leads to the
development of new products.

Chemists are employed in all parts of the country, but they are con­
centrated 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, gradu­
ate training is required for most research jobs, and most college
teaching jobs require a Ph.D. degree.
Many colleges and universities offer a bachelor’s degree program
in chemistry, about 590 of which are approved by the American
Chemical Society. Several hundred 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 analyti­
cal, inorganic, organic, and physical chemistry, undergraduate chem­
istry majors usually study biological sciences, mathematics, and
physics. Computer courses are also important, as chemists are
increasingly using computers as a tool in their everyday work.
Although graduate students typically specialize in a subfield of
chemistry, such as analytical chemistry or polymer chemistry, spe­
cialization is usually unnecessary on the undergraduate level. In fact,
undergraduates who are broadly trained have more flexibility when
jobhunting or changing jobs than if they narrowly define their inter­
ests. Some employers provide new bachelor’s degree chemists with
additional training or education, in order to tailor the chemist to a
specific job or type of work.
>
In government or industry, beginning chemists with a bachelor’s
degree work in technical sales or services, or assist senior chemists in
research and development laboratories. Some may work in research
positions, analyzing and testing products, but these are often techni­
cians’ positions, with limited upward mobility. Many employers pre­
fer chemists with a master’s degree or a Ph.D. to work in basic and
applied research, and a Ph.D. is 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 eventually move into management.
Many people with a bachelor’s degree in chemistry enter other
occupations in which a chemistry background is helpful, such as
technical writers and manufacturers’ or wholesale sales representa­
tives in chemical marketing. Some enter medical, dental, veterinary,
or other health profession schools. Others enter a wide range of occu­
pations with little or no connection to chemistry.
Chemistry graduates may become high school teachers. However,
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.
17

Job Outlook
Chemists are expected to have very good employment opportunities
through the year 2005 because employment is expected to grow about
as fast as the average for all occupations and the number of degrees
granted in chemistry is not expected to increase enough to meet
future demand. The chemical industry, which faced many problems
in the 1980’s, is now much healthier. However, it is still subject to
cyclical fluctuations which affect employment of chemists, particu­
larly those in the industrial chemical and oil industries. Expanded
research and development, especially in pharmaceutical firms,
biotechnology firms, and firms producing specialty chemicals, are
expected to contribute to employment growth. Chemists with special­
ized knowledge in polymers and synthetics, analytical chemistry, and
food chemistry should have especially good job opportunities. Ph.D.
chemists are, and should continue to be, in strong demand, as
employers are increasingly expecting their researchers to have
advanced education. Despite the expected growth, most openings will
result as chemists retire, transfer to other occupations, or leave the
occupation for other reasons.
Earnings
According to a 1990 survey by the American Chemical Society, the
median starting salary for recently graduated chemists with a bache­
lor’s degree was about $23,000 a year; with a master’s degree
$30,000; with a Ph.D., $44,000.
The American Chemical Society also reports that the median
salary of their members (with varying amounts of experience) with a
bachelor’s degree was $39,000 a year in 1990; with a master’s
degree, $45,000; with a Ph.D., $55,000.
In 1991, chemists in the Federal government earned an average
salary of $46,847.
Related Occupations
The work of chemical engineers, occupational safety and health
workers, agricultural scientists, biological scientists, and chemical
technicians is closely related to the work done by chemists. The work
of other physical and life science occupations may also be similar to
that of chemists.

(D.O.T. 024.061 except -014, .161, and .167)

Nature of the Work
Geologists and geophysicists study the physical aspects and history
of the earth. They identify and examine surface rocks and buried
rocks recovered by drilling, study information collected by satellites,
conduct geological 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 deeply buried rock layers. Many geolo­
gists and geophysicists 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 these scientists’ role in studying all aspects of
the earth.
Geoscientists play an increasingly important part in studying, pre­
serving, and cleaning up the environment. Many design and monitor
waste disposal sites, preserve water supplies, and reclaim contaminat18

ed land and water to comply with stricter Federal environmental
rules. They also help locate safe sites for hazardous waste facilities,
nuclear powerplants, and landfills.
Geologists and geophysicists examine chemical and physical prop­
erties of specimens in laboratories, sometimes under controlled tem­
perature 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 lab­
oratory instruments is used, including X-ray diffractometers, which
determine the crystal structure of minerals, and petrographic micro­
scopes, for study of rock and sediment samples. Earthquakes are
located and their intensities determined using seismographs, instru­
ments 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, tunnels,
and highways. Some administer and manage research and exploration
programs and others become general managers in petroleum and min­
ing companies.
Geology and geophysics are closely related fields, but there are
some major differences. Geologists study the composition, structure,
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. Geo­
physicists use the principles of physics and mathematics to study not
only the earth’s surface but its internal composition, fresh water,
atmosphere, and oceans as well as its magnetic, electrical, and gravi­
tational forces. Both, however, commonly apply their skills to the
search for natural resources and solving environmental problems.
Geologists and geophysicists usually specialize. Geological
oceanographers study the ocean floor. They collect information
using remote sensing devices aboard surface ships or underwater
research craft. Physical oceanographers study the physical aspects
of oceans such as currents and the interaction of the surface of the
sea with the atmosphere. Geochemical oceanographers study the
chemical composition, dissolved elements, and nutrients of oceans.
Although biological scientists who study ocean life are also called
oceanographers (as well as marine biologists), the work they do and
the training they need are related to biology rather than geology or
geophysics. (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. Mineralogists ana­
lyze and classify minerals and precious stones according to composi­
tion and structure. Paleontologists study fossils found in geological
formations to trace the evolution of plant and animal life and the
geologic history of the earth. Seismologists interpret data from seis­
mographs and other instruments to locate earthquakes and earth­
quake-related faults. Stratigraphers study the distribution and
arrangement of sedimentary rock layers by examining their fossil
and mineral content. Meteorologists sometimes are classified as geo­
physical scientists. (See the statement on meteorologists elsewhere
in the Handbook.)
Working Conditions
While some geoscientists spend the majority of their time in an
office, others divide their time between fieldwork and office or labo­
ratory work. Geologists often travel to remote field sites by helicopter
or four-wheel drive vehicles and cover large areas by foot. Explo­
ration geologists and geophysicists often work overseas or in remote
areas, and job relocation is not unusual. Geological and physical
oceanographers may spend considerable time at sea.
Employment
Geologists and geophysicists held almost 48,000 jobs in 1990. In
addition, thousands of persons held geology, geophysics, and
oceanography faculty positions in colleges and universities. (See the
statement on college and university faculty elsewhere in the Hand­
book.)

Geologists determine the composition of rock specimens in laboratories.
About 4 in 10 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 and architectural
services, which often provide services to oil and gas companies.
About 1 geologist in 7 was self-employed; most of these were consul­
tants to industry or government.
The Federal Government employed about 6,000 geologists, geo­
physicists, oceanographers, and hydrologists in 1989. Over one-half
worked for the Department of the Interior in the U.S. Geological Sur­
vey, the Bureau of Land Management, the Minerals Management
Service, the Bureau of Mines, and the Bureau of Reclamation. Others
worked for the Departments of Defense, Agriculture, Commerce, 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 non­
profit research institutions. Some were employed 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
advancement potential usually require at least a master’s degree in
geology or geophysics. Persons with strong backgrounds in physics,
mathematics, or computer science also may qualify for some geo­
physics jobs. A Ph.D. degree is essential for most research and col­
lege or university teaching positions, and is becoming more important
for employment in some Federal agencies.
Over 500 colleges and universities offer a bachelor’s degree in
geology or geophysics. Other programs offering related training for
beginning geological scientists include geophysical technology, geo­
physical engineering, geophysical prospecting, engineering geology,

petroleum geology, and geochemistry. In addition, more than 270 uni­
versities award advanced degrees 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, stratigra­
phy, and structural geology) are important for all geoscientists. How­
ever, 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
exploration 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 man­
agement 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.
In the past, most jobs for geologists and geophysicists were in or
related to the petroleum industry, particularly in the exploration for
oil and gas. This industry is subject to cyclical fluctuations. Low oil
prices usually cause exploration activities to be curtailed—resulting
in layoffs of many geologists and geophysicists. As a result of gener­
ally poor job prospects in the past few years, the number of students
enrolling in geology and geophysics has dropped considerably. How­
ever, when exploration activities increase, geologists and geophysi­
cists should have excellent employment opportunities because many
experienced geologists and geophysicists have left the occupation.
Also, the number of degrees granted in 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 geologists and geophysicists available to
fill them.
Environmental protection and regulatory geoscience are becoming
important fields of work for geoscientists with the appropriate train­
ing, and are additional sources of employment growth. In particular,
jobs requiring training in hydrology and geochemistry should be in
demand.
Replacement needs in colleges and universities are expected to
increase as the rate of retirements increases over the next 15 years.
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 $23,463 a year in 1990.
According to a 1990 American Geological Institute survey, the
average starting salaries for inexperienced geoscientists were about
$23,900 for those with a bachelor’s degree, $26,500 for those with a
master’s degree, and $33,300 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, and mining and minerals industries
offered average starting salaries of $32,500 and $26,700, respective­
ly, for bachelor’s degree holders, while in research institutions, col­
leges, and universities, new hires with a bachelor’s degree averaged
about $20,000.
Although the petroleum, mineral, and mining industries offer high­
er salaries, the competition in these areas is normally intense, and the
job security less than in other areas.
In 1991, the Federal Government’s average salary for all geologists
in managerial, supervisory, and nonsupervisory positions was
$47,669; for all geophysicists, $52,025; for all hydrologists, $43,794;
and for all oceanographers, $49,521.
Related Occupations
Many geologists and geophysicists work in the petroleum and natural
gas industry. This industry also employs many other workers in the
scientific and technical aspects of petroleum and natural gas explo19

ration and extraction, including drafters, engineering technicians, sci­
ence technicians, petroleum engineers, and surveyors. Also, some
physicists, chemists, and meteorologists, as well as mathematicians,
computer scientists, soil scientists, and mapping scientists, do related
work.

Meteorologists
(D.O.T. 025.062-010)

Nature of the Work
Meteorology is the study of the atmosphere, the air that surrounds the
earth. Meteorologists study the atmosphere’s physical characteristics,
motions, and processes, and the way the atmosphere affects the rest
of our environment. The best-known application of this knowledge is
in forecasting the weather. However, weather information and meteo­
rological research also are applied in air-pollution control, agricul­
ture, air and sea transportation, and the study of trends in the earth’s
climate such as global warming or ozone depletion.
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 apply physical and mathematical relationships to make
short- and long-range weather forecasts. Their information comes
from weather satellites, weather radar, and remote sensors and
observers in many parts of the world. Meteorologists use sophisticat­
ed 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.
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. Cli­
matologists analyze past records of wind, rainfall, sunshine, and tem­
perature in specific areas or regions. Their studies are used to design
buildings and to plan heating and cooling systems, effective land use,
and agricultural production. Much meteorological research is cen­
tered on improving weather forecasting, mainly through building bet­
ter computer models of the atmosphere, including interactions with
land and water surfaces.
Working Conditions
Jobs in weather stations, most of which operate around the clock 7
days a week, often involve night work and rotating shifts. Weather
stations are often at airports, in or near cities, and in isolated and
remote areas. Meteorologists in smaller weather offices generally
work alone; in larger ones, they work as part of a team. Meteorolo­
gists not doing forecasting work regular hours, usually in offices.
20

Federal Reserve Bank of St. Louis

Employment
Meteorologists held about 5,500 jobs in 1990. The largest employer of
civilian meteorologists is the National Oceanic and Atmospheric
Administration (NOAA), which employs about 1,800 meteorologists.
About two-thirds of NOAA’s meteorologists work in the National
Weather Service at stations in all parts of the United States. The
remainder 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 consultants,
research and testing services, and computer and data processing ser­
vices.
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.)
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 is the usual minimum requirement for a beginning job as a mete­
orologist.
The educational requirements for entry level meteorologists in the
Federal Government call for a bachelor’s degree—not necessarily in
meteorology—with at least 20 semester hours of meteorology cours­
es, including 6 hours in weather analysis and forecasting and 6 hours
in dynamic meteorology. In addition to meteorology coursework, 6
hours of differential and integral calculus and 6 hours of calculusbased physics are required. In 1993, these requirements will be
upgraded to include 3 hours of computer science and 6 hours of
coursework appropriate for a physical science major, such as statis­
tics, chemistry, physical oceanography, or physical climatology.
Although positions in operational meteorology are available for those
with only a bachelor’s degree, obtaining a graduate degree enhances
advancement potential. A master’s degree is usually necessary for con­
ducting research and development, and a Ph.D. is usually required for
college teaching. Students who plan a career in teaching or research and
development need not necessarily major in meteorology as an under­
graduate. In fact, a bachelor’s degree in mathematics, physics, or engi­
neering 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,
although 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 Nation­
al Weather Service and other employers are offered at the college
they are considering. Upgraded educational and training require­
ments, such as computer science courses, additional meteorology
courses, and a strong background in mathematics and physics, are
expected to become more important to prospective employers as

As weather equipment and radar systems become more complex,
educational and training requirements for meteorologists will increase.

weather equipment and radar systems become more complex. Many
programs combine the study of meteorology with another field, such
as agriculture, engineering, or physics. For example, hydrometeorolo­
gy is the blending of hydrology (the science of the earth’s water) and
meteorology and is an emerging field concerned with the impact of
precipitation on the hydrologic cycle and the environment.
Beginning meteorologists often do routine data collection, compu­
tation, or analysis and are given more difficult assignments as they
gain experience. Experienced meteorologists may advance to various
supervisory or administrative jobs. Increasing numbers of meteorolo­
gists establish their own weather consulting services.
Job Outlook
Employment of meteorologists is expected to grow faster than the
average for all occupations through the year 2005. The National
Weather Service, which employs many meteorologists, is increasing
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 upgrad­
ing of meteorological technicians, there still should be many more
openings in the National Weather Service in the next 5 to 10 years
than there have been in the past. Employment of meteorologists in
other parts of the Federal Government is not expected to increase.
Many new jobs, though, will be created in private industry with the
increased use of private weather forecasting and meteorological ser­
vices by farmers, commodity investors, utilities, transportation and
construction firms, and radio and TV stations. For people in these and
other areas, even a slight improvement in the detail and accuracy of
weather information and forecasts over the general information pro­
vided by the National Weather Service can be a significant benefit.
However, because many customers for private weather services are in
industries that are sensitive to fluctuations in the economy, the sales
and growth of private weather services are dependent on the health of
the economy.
Despite the projected faster-than-average growth, most of the job
openings 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 employed by the Federal Gov­
ernment was $44,706 in 1991. In 1991, meteorologists in the Federal
Government with a bachelor’s degree and no experience received a
starting salary of $16,973 or $21,023 a year, depending on their col­
lege grades. Those with a master’s degree could start at $21,023 or
$25,717; those with the Ph.D. degree, at $31,116 or $37,294.
Related Occupations
Workers in other occupations concerned with the physical environ­
ment include oceanographers, geologists and geophysicists, hydrolo­
gists,and civil and environmental engineers.

Physicists and Astronomers
(D.O.T. 021.067-010; 023.061-010, -014, .067; 079.021-010 and -014)

Nature of the Work
Physicists attempt to discover basic principles governing the structure
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 origin of the
universe, while others work in practical areas such as the develop­
ment of advanced materials, electronic devices, and medical equipment.
Physicists design and perform experiments with lasers, cyclotrons,
telescopes, mass spectrometers, and other equipment. Based on

https://fraser.stlouisfed.org
Federal Reserve Bank of St. Louis

observations and analysis, they formulate theories and laws to
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, materials,
communications, aerospace technology, and medical instrumentation.
Astronomy is sometimes considered a subfield of physics.
Astronomers use the principles of physics and mathematics to learn
about the fundamental nature of the universe and 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 basic
research to increase scientific knowledge. For example, they investi­
gate the structure of the atom or the nature of gravity.
Practical applications of basic research discoveries are made by
physicists who conduct applied 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 integrated circuits used in computers.
Physicists also design research equipment. This equipment often
has additional unanticipated uses. For example, lasers (devices that
amplify light and emit it in a highly directional, intense beam) are
used in surgery; microwave devices are used for ovens; and measur­
ing instruments 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.
Some physics research is done in small or medium-size laborato­
ries. However, many experiments in plasma, nuclear, particle, and
some other areas of physics require extremely large, expensive equip­
ment 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 quantities
of data and write scientific papers on their findings. Most astronomers
spend only a few weeks each year making observations with tele­
scopes, radio telescopes, and other instruments. Contrary to the popu­
lar image, astronomers almost never make observations by looking
directly through a telescope because enhanced photographic and elec­
tronic detecting equipment is more effective 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;
health physics; plasma physics; or the physics of fluids. Some spe­
cialize in a subdivision of one of these subfields; for example, within
solid-state physics, specialties include superconductivity, crystallog­
raphy, and semiconductors. However, since all physics involves the
same fundamental principles, specialties may overlap, and physicists
may switch from one subfield to another.
Growing numbers of physicists work in combined fields such as
biophysics, chemical physics, and geophysics. Furthermore, the prac­
tical applications of physicists’ work increasingly have merged with
engineering.
Working Conditions
Physicists usually 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 temporarily at
national or international facilities with unique equipment such as par­
ticle accelerators. Astronomers who make observations may travel to
observatories, which are usually in remote locations, and frequently
work at night.
Employment
Physicists and astronomers held nearly 20,000 jobs in 1990. About
the same number held physics faculty positions in colleges and uni­
versities. (See the statement on college and university faculty else­
where in the Handbook.) About two-fifths of all nonfaculty physicists
worked for research, development, and testing laboratories. The Fed­
eral Government employed over one-fifth, mostly in the Departments
of Defense and Commerce and in the National Aeronautics and Space
21

Many Ph.D. physics and astronomy graduates choose to take a
postdoctoral position, which is helpful for physicists who want to
continue 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 supervision of
more senior scientists. After some experience, they are assigned 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.

Physicists usually specialize in a suhfield ofphysics, such as optics,
acoustics, or atomic and molecular physics.
Administration. Others worked in colleges and universities in nonfac­
ulty positions and for aerospace firms, noncommercial research labo­
ratories, electrical equipment manufacturers, engineering services
firms, and the transportation equipment industry.
Although physicists are employed in all parts of the country, most
are in areas that have heavy industrial concentrations and large
research and development laboratories.
Training, Other Qualifications, and Advancement
A doctoral degree is the usual educational requirement for physicists
and astronomers, since most jobs are in research and development 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 scientif­
ic fields, to work as technicians, or to assist in setting up laboratories.
Some may qualify for applied research jobs in private industry and in
the Federal Government, and a master’s degree is often sufficient for
teaching jobs in 2-year colleges. Astronomy bachelor’s degree hold­
ers usually enter a field unrelated to astronomy. (See statements on
engineers, geologists and geophysicists, computer programmers, and
computer 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
include mechanics, electromagnetism, optics, thermodynamics, and
atomic, nuclear, and particle physics.
About 170 colleges and universities have physics departments
which offer Ph.D. degrees in physics. Graduate students usually con­
centrate in a subfield of physics such as elementary particles or con­
densed matter. Many begin studying for their doctorates immediately
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 doc­
toral 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 highly
recommended, 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.

Job Outlook
The employment of physicists and astronomers is expected to grow
more slowly than the average for all occupations through the year
2005. Because a large proportion of physicists and astronomers are
employed on research projects, changes in research and development
budgets could have a major impact on the growth of jobs. In poor
economic times, industrial and governmental research and develop­
ment budgets may not grow much, causing little employment growth
in these occupations. However, employment opportunities are expect­
ed to improve in the late 1990’s, when many physics and astronomy
faculty will be eligible for retirement.
As is the case in many occupations, employment growth for physi­
cists differs by subfield. The number of positions available for certain
specialists rises and falls depending on which research and develop­
ment projects are funded.
Persons with only a bachelor’s degree in physics are not qualified
to enter most physicist jobs. However, many find jobs as engineers,
technicians, computer specialists, or high school physics teachers.
(See the statements on these occupations elsewhere in the Hand­
book.)
Earnings
Starting salaries for physicists averaged about $29,200 a year in 1990
for those with a bachelor’s degree, $31,500 for those with a master’s
degree, and $41,500 for those with a doctoral degree, according to the
College Placement Council.
The American Institute of Physics reported a median salary of
$58,000 in 1990 for its members with Ph.D.’s.
Average earnings for physicists in the Federal Government in 1991
were $56,642 a year, and for astronomy and space scientists, $60,354.
Related Occupations
The work of physicists is closely related to that of other scientific
occupations such as chemist, geologist, and geophysicist. Engineers
and engineering and science technicians also use the principles of
physics in their work.

Drafters
(D.O.T. 001.261; 002.261; 003.131, .261 except -010, 281; 005.281; 007.161­

.261-010; and 726.364-014)

Nature of the Work
Drafters prepare technical drawings used by production workers to
build spacecraft, industrial machinery and other manufactured prod­
ucts, office buildings, houses, bridges, and other structures. 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, working
from rough sketches, drafters use knowledge of standardized building
techniques to draw the details of a structure, or employ knowledge of
engineering theory to arrange the parts of a machine and determine
the number and kind of fasteners needed. For this, they may use tech­
nical handbooks, tables, and calculators.
There are two methods by which drawings are prepared. In the tra­
ditional method, drafters sit at drawing boards and use compasses,
dividers, protractors, triangles, and other drafting devices to prepare
the drawing manually. Today, drafters also use computer-aided draft­
ing (CAD) systems. They use computer work stations to create the
drawing on a video screen. They may put the drawing on paper or
just store it electronically. These systems permit drafters to easily
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.
Despite CAD’s advantages, much drafting is still done manually,
partly because of the cost of CAD systems, but also because of prob­
lems in shifting office procedures to the use and storage of CAD-gen­
erated drawings. However, the cost of CAD systems is dropping
rapidly, and by the year 2005 it is likely that almost all drafters will
use CAD systems regularly, although manual drafting probably will
still be used in certain applications.
Many drafters specialize. Architectural drafters draw architectural
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 work­
ers who erect, install, and repair electrical equipment and wiring in
powerplants, electrical distribution systems, and buildings.
Electronic drafters draw wiring diagrams, circuit board diagrams,
schematics, and layout drawings used in the manufacture, installa­
tion, and repair of electronic equipment.
Civil drafters prepare drawings and topographical and relief maps
used in civil engineering projects such as highways, bridges, flood
control projects, and water and sewage systems.
Mechanical drafters draw detailed working diagrams of machinery
and mechanical devices, including dimensions, fastening methods,
and other engineering information.

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 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 equip­
ment, and faculty qualifications.
Technical institutes offer intensive technical training but less theo­
ry 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 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. 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 useful
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 local
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 of job, but often this is gained on the job. Some correspon­
dence schools also offer training for drafters.
Those planning careers in drafting should be able to draw freehand
three-dimensional objects and do detailed work accurately and neatly.
Artistic ability is helpful in some specialized fields, as is knowledge

Working Conditions
Drafters usually work in well-lighted and well-ventilated rooms.
They often sit at drawing boards or computer terminals for long peri­
ods of time. Doing detailed work may cause eyestrain and back dis­
comfort.
Employment
Drafters held about 326,000 jobs in 1990. About 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 onethird worked in durable goods manufacturing industries, such as
machinery, electrical equipment, and fabricated metals; and the
remainder were mostly employed in the construction, transportation,
communications, and utilities industries.
About 14,000 drafters worked in government in 1990, primarily at
the State and local level. Most drafters in the Federal Government
worked for the Department of Defense.
Training, Other Qualifications, and Advancement
Employers prefer applicants for drafting positions who have posthigh school training in technical institutes, junior and community col­
leges, or extension divisions of universities. Employers are most

Drafting is often done with computer-aided systems.

of manufacturing and construction methods. In addition, prospective
drafters should be able to work closely with engineers, surveyors,
architects, and other workers.
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 aver­
age for all occupations through the year 2005. Industrial growth and
the increasingly complex design problems associated with new prod­
ucts and processes will greatly increase the demand for drafting ser­
vices. However, greater use of CAD equipment—which increases
drafters’ productivity—is expected to offset some of this growth in
demand. Although some in the field had expected that CAD systems
would decrease drafters’ employment, this has not occurred in most
situations where CAD systems have been installed. In fact, it now
appears that productivity gains from CAD have been relatively modest.
One reason is that CAD systems make it easier to produce more varia­
tions of a design. As in other areas, the ease of obtaining computer­
generated information stimulates a demand for more information.
Also, drawing the initial design on a CAD system is almost as time
consuming as when it is done manually. Although growth in employ­
ment will create many job openings, most job openings are expected to
arise as drafters transfer to other occupations or leave the labor force.
Drafters are highly concentrated in industries that are sensitive to
cyclical swings in the economy, such as engineering and architectural
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 $25,900 in 1990; the middle 50 percent earned between
$19,300 and $33,500 annually; 10 percent earned more than $41,600;
10 percent earned less than $15,400.
Experienced drafters in manufacturing, transportation, and utilities
averaged between $18,600 and $31,500 a year in 1990. Senior
drafters averaged about $36,200 a year in 1990.
Related Occupations
Other workers who prepare or analyze detailed drawings and make
precise calculations and measurements include architects, landscape
architects, engineers, engineering technicians, science technicians,
photogrammetrists, and surveyors.

Nature of the Work
Engineering technicians use the principles and theories of science,
engineering, and mathematics to solve problems in research and
development, manufacturing, sales, construction, and customer ser­
vice. Their jobs are more limited in scope and more practically ori­

ented than those of scientists and engineers. Many engineering tech­
nicians 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, calculate
or record the results, and assist 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.
Engineering technicians also work as field representatives of man­
ufacturers, wholesalers, or retailers. They help customers install, test,
operate, and maintain complex technical equipment, and may write
repair or operating manuals.
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 inspect
water and wastewater treatment systems to ensure that pollution con­
trol requirements are met. Others estimate construction costs and
specify materials to be used. (See statement on cost estimators else­
where 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, navigation­
al equipment, and computers, often using measuring and diagnostic
devices to test, adjust, and repair equipment. Workers who only repair
electrical and electronic equipment are discussed in several other
statements elsewhere in the Handbook. Many of these repairers 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
develop machinery and other equipment by making sketches and
rough layouts. They also record data, make computations, analyze
results, and write reports. When planning production, mechanical
engineering technicians prepare layouts and drawings of the assembly
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.
Working Conditions
Most engineering technicians work regular hours in laboratories,
offices, electronics shops, industrial plants, or construction sites. Ser­
vice representatives usually spend much of their time working in cus­
tomers’ establishments. Some may be exposed to electrical shock and
other hazards from equipment.
Employment
Engineering technicians held about 755,000 jobs in 1990. About twofifths worked in manufacturing, mainly in the electrical and electron­
ic machinery and equipment, transportation equipment, and industrial
machinery industries. Over one-fifth worked in service industries,
mostly in engineering or business services companies who do engi­
neering work on contract for government, manufacturing, or other
organizations.
In 1990, the Federal Government employed about 65,000 engineer­
ing technicians. About three-fifths worked for the Department of
Defense; others worked for the Departments of Transportation, Agri­
culture, and Interior, the Tennessee Valley Authority, and the National
Aeronautics and Space Administration. State governments employed
about 37,000 and local governments about 26,000.
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

ed by employers. Some additional training may be needed, depending
on the military skills acquired and the kind of job, 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 technicians
need an aptitude for mathematics and science. For design work, cre­
ativity 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 independently and
deal effectively with customers.
Engineering technicians usually begin by doing routine work under
the close supervision of an experienced technician, engineer, or scien­
tist. As they gain experience, they are given more difficult assign­
ments with only general supervision. Some engineering technicians
eventually become supervisors, and a few, engineers.

who will require less on-the-job training and supervision. Training is
available at technical institutes, junior and community colleges,
extension divisions of colleges and universities, public and private
vocational-technical schools, and through some technical training
programs in the Armed Forces. Persons with college courses in sci­
ence, engineering, and mathematics may also qualify for some posi­
tions but may need additional specialized training and experience.
In some cases, training can be obtained on the job or through
apprenticeship programs or correspondence schools.
Many types of publicly and privately operated schools provide
technical training. The kind and quality of programs vary consider­

Job Outlook
Well-qualified engineering technicians should experience good
employment opportunities through the year 2005. Employment is
expected to increase faster than the average for all occupations due
to expected continued rapid growth in the output of technical prod­
ucts. Competitive pressures and advancing technology will force
companies to improve and update manufacturing facilities and
product designs more rapidly than in the past. However, like engi­
neers, employment 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 engineering technicians, such as civil engineering and aeronauti­
cal engineering technicians, experience greater cyclical fluctuations
than others. Technicians whose jobs are defense related may be laid
off in times of defense cutbacks.
Despite the projected faster-than-average growth, most job open­
ings will be to replace technicians who transfer to other occupa­
tions or leave the labor force.
Earnings
In 1991, engineering technicians in private industry earned an aver­
age annual salary of $20,400 at the most junior level. Engineering
technicians with more experience and the ability to work with little
supervision averaged $28,300, and those in supervisory or senior
level positions averaged $38,800.
In the Federal Government, engineering technicians could start at
$13,515, $15,171, or $16,973 in 1991, depending on their educa­
tion and experience. In 1991, the average salary for engineering
technicians in supervisory, nonsupervisory, and management posi­
tions in the Federal Government was $33,688; for electronics tech­
nicians, $38,516; and for industrial engineering technicians,
$34,008.
Related Occupations
Engineering technicians apply scientific and engineering principles
usually acquired in postsecondary programs below the baccalaure­
ate level. Occupations of a similar nature include science techni­
cians, drafters, surveyors, broadcast technicians, and health
technologists and technicians.

Science Technicians
(List of D.O.T. codes available on request from the Chief, Division of Occu­
pational 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 nature of the work of science
technicians in research and development. The increasing use of
robotics to perform many routine tasks formerly done by technicians
has freed technicians to operate other, more sophisticated laboratory
equipment. Science technicians make extensive use of computers,
computer-interfaced equipment, robotics, and high-technology indus­
trial applications such as biological engineering.
Technicians set up, operate, and maintain laboratory instruments,
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 increase 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 organ­
isms. Many help conduct medical research, helping to find a cure for
cancer or AIDS, for example, or they may help conduct pharmaceuti­
cal research. Biological technicians also analyze organic substances
such as blood, food, and drugs; some examine evidence in criminal
investigations. Biological technicians working in biotechnology labs
use the knowledge and techniques gained from basic research by sci­
entists, including gene splicing and recombinant DNA, and apply
these techniques in product development.
Chemical technicians work with chemists and chemical engineers,
developing and using chemicals and related products and equipment.
Most do research and development, testing, or other laboratory work.
For example, they might test packaging for design, materials, and
environmental acceptability; assemble and operate new equipment to
develop new products; improve product quality; or develop new pro­
duction techniques. Some chemical technicians collect and analyze
samples of air and water to monitor pollution levels. Those who focus
on basic research might produce compounds through complex organ­
ic synthesis.
Nuclear technicians operate nuclear test and research equipment,
monitor radiation, and assist nuclear engineers and physicists in
research. 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 or
by analysis of the mud from wells. In oil and gas exploration, they
collect and examine geological data or test geological samples to
determine petroleum and mineral content. Some petroleum techni­
cians, called scouts, collect information about oil and gas well
drilling 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
26

toxic chemicals, nuclear technicians may be exposed to radiation, and
biological technicians sometimes work with disease-causing organ­
isms or radioactive agents. However, there is little risk if proper safe­
ty procedures are followed.
Employment
Science technicians held about 246.000 jobs in 1990. Almost 40 per­
cent worked in manufacturing, especially in the chemical, petroleum
refining, and food processing industries. Almost 20 percent worked
in colleges and universities and another 11 percent worked in
research and testing services.
In 1990, the Federal Government employed about 20,000 science
technicians, mostly in the Departments of Defense, Agriculture, Inte­
rior, 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 associate
degrees in a specific technology or a more general education in sci­
ence 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 of programs at technical institutes
varies, although 2-year associate degree programs are common. Some
of these schools offer cooperative-education programs, allowing stu­
dents 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 because they
can’t find or don’t want a job as a scientist or because employers
couldn’t find properly trained technicians with less education. In
some cases, they may be able to move into jobs as scientists, man­
agers, 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 pro-

gram, should be laboratory oriented, with an emphasis on “bench”
skills. Communication skills are important, and technicians should be
able to work well with others since technicians often are part of a
team. Because computers and computer-interfaced equipment are
increasingly used in research and development laboratories, computer
skills are also valuable.
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 encompass­
es extensive hands-on experience with a variety of laboratory equip­
ment, including computers and related equipment, usually require a
much shorter period of on-the-job training. As they gain experience,
they take on more responsibility and carry out assignments under
only general supervision. Some eventually become supervisors.
Job Outlook
Science technicians with good technical and communications skills
should experience very good employment opportunities through the
year 2005. Employment is expected to increase about as fast as the
average for all occupations through the year 2005 due to an expected
growth in scientific research and development and production of
technical products. Because of the growth of biotechnology, employ­
ment of biological technicians is expected to grow faster than for
most other science technicians. Job opportunities for chemical techni­
cians are also expected to be very good. Employment of nuclear and
petroleum technicians is expected to grow more slowly.
Despite the projected growth, most job openings will arise from
the need to replace technicians who transfer to other occupations or
leave the labor force.
Earnings
Median annual earnings of science technicians were about $24,700 in
1990; the middle 50 percent earned between $17,700 and $32,400.
Ten percent earned less than $13,700, and 10 percent earned over
$42,600.
In the Federal Government in 1991, science technicians could start
at $13,515, $15,171, or $16,973, depending on their education and
experience. The average salary for biological technicians employed
by the Federal Government in 1991 was $22,863; for mathematical
technicians, $26,211; for physical science technicians, $28,060; for
geodetic technicians, $33,096; for hydrologic technicians, $26,928;
and for meteorologic technicians, $33,279.
Related Occupations
Other technicians who apply scientific principles at a level usually
taught in 2-year associate degree programs include engineering tech­
nicians, broadcast technicians, drafters, and health technologists and
technicians. Some of the work of agricultural and biological techni­
cians is related to that in agriculture and forestry occupations.

Surveyors
(D.O.T. 018.131, .167 except -022, .261, .262, .281; 024.061-014; and
184.167-026)

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; write descriptions of land for deeds, leases,
and other legal documents; define air space for airports; and measure
construction and mineral sites. They are assisted by survey techni­
cians, who operate surveying instruments and collect information.
Mapping scientists and other surveyors collect geographic informa­
tion and prepare maps and charts.

https://fraser.stlouisfed.org
Federal Reserve Bank of St. Louis

Land surveyors manage one or more survey parties who measure
distances, directions, and angles between points and elevations of
points, lines, and contours on the earth’s surface. They plan the field­
work, select known survey reference points, and determine the pre­
cise location of all important features of the survey area. They
research 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 official
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
either 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 hold the
vertical rods 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 signals
transmitted by satellites. The system was designed by the military for
the navigation of its planes, tanks, ships, and other equipment. To use
it, a surveyor places a satellite receiver, the size of a backpack, on a
desired point. The receiver collects information from several satel­
lites at once to triangulate the position precisely. Two receivers are
generally used, one at a known point and the other at the unknown
point, and are operated simultaneously. The receiver can also be
placed in a car to trace out road systems or for other uses. The system
is operative yet not totally complete now, but when all the planned
satellites are placed in orbit and as the cost of the receivers are
reduced, 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 scien­
tists include workers in several occupations. Cartographers prepare
maps using information provided by geodetic surveys, aerial pho­
tographs, and satellite data. Photogrammetrists prepare maps and
drawings by measuring and interpreting aerial photographs, using
analytical processes and mathematical formulas. Photogrammetrists
make detailed maps of areas that are inaccessible or difficult to sur­
vey by other methods. Map editors develop and verify map contents
from aerial photographs and other reference sources.
Some surveyors perform specialized functions which are closer to
mapping science than traditional surveying. Geodetic surveyors use
high-accuracy techniques, including satellite observations, to measure
large areas of the earth’s surface. Geophysical prospecting surveyors
mark sites for subsurface exploration, usually petroleum related.
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 GPS, Geographic Information
Systems (GIS), which are computerized data banks of spatial data,
new earth resources data satellites, and improved aerial photography.
The older specialties of photogrammetrist or cartographer are becom­
ing a new one, geographic information specialist. Further, many
observe that the functions of mapping science and surveying are
merging into a broader field, that of the collection and analysis of
geographic spatial information.
Working Conditions
Surveyors usually work an 8-hour day 5 days a week. Sometimes
27

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 strenuous
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 com­
mute long distances or temporarily relocate near a survey site. They
also spend considerable time in an office, 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 108,000 jobs in 1990. Engineering, architec­
tural, and surveying firms employ over three-fifths of all surveyors.
Federal, State, and local government agencies employ about onefourth. Major Federal Government employers are the U.S. Geological
Survey, the Bureau of Land Management, the Army Corps of Engi­
neers, the Forest Service, the National Ocean Survey, and the
Defense Mapping Agency. Most surveyors in State and local govern­
ment work for highway departments and urban planning and redevel­
opment agencies. Construction firms, mining and oil and gas
extraction companies, and public utilities also employ surveyors.
About 6,000 surveyors 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. 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 technology and an increase in licensing standards,
more formal education is now required. Most States at the present
time require some formal post-high school education courses and 5 to
12 years of surveying experience to gain licensure. However, require­
ments vary among the States. Generally, the quickest route is a com­
bination of 4 years of college, 2 to 4 years of experience (a few States
do not require any), and passing the State licensing examination. 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 usually
start as a helper. Beginners with postsecondary school training in sur­
veying can generally start as technicians. With on-the-job experience
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 requirements).
Cartographers and photogrammetrists usually have a bachelor’s
degree in engineering or a physical science, although it is possible to
enter these jobs through experience as a photogrammetric or carto­
graphic technician. Most cartographic and photogrammetry techni­
cians have had some specialized postsecondary school training. With
the development of Geographic Information Systems, cartographers,
photogrammetrists, and other mapping scientists now need more edu­
cation and experience in the use of computers than in the past.
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. Leadership qualities are impor­
tant for party chief and other supervisors.
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 about as fast as 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.
The anticipated growth in construction through the year 2005
should create jobs for surveyors who lay out streets, shopping cen­
ters, housing developments, factories, office buildings, and recreation
areas. Road and highway construction and improvement also should
create new surveying positions. However, employment may fluctuate
from year to year along with constmction 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.
Higher levels of technology, a national trend of upgraded licensing
requirements, and the increased demand for geographic spatial data
(as opposed to traditional surveying services) mean that opportunities
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 employ­
ment opportunities for surveyors and survey technicians who have
the educational background to use it while reducing employment
opportunities for those who do not.
Earnings
According to the limited data available, the median annual earnings
for surveyors were about $25,600 in 1990.

In 1990, the median annual earnings for survey technicians were
about $23,200 a year. The middle 50 percent earned between $17,400
and $32,100 a year; 10 percent earned less than $14,500 a year; 10
percent earned more than $43,700 a year.
In 1991, high school graduates with little or no training or experi­
ence earned about $12,385 annually at entry level jobs on survey
crews with the Federal Government. Those with 1 year of related
postsecondary training earned $13,515. Those with an associate
degree that included courses in surveying generally started as instru­
ment assistants with an annual salary of $15,171. In 1991, persons
starting as land surveyors or cartographers with the Federal Govern­
ment earned $16,973 or $21,023 a year, depending on their qualifica­
tions. The average annual salary for Federal land surveyors in 1991
was $37,024, for surveying technicians, $21,779, for cartographers,
$38,957, for cartographic technicians, $27,146, for geodesists,
$43,769, and for geodetic technicians, $33,096.

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 composi­
tion, 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.
