PREFACE
This is the third of four volumes of Tomorrow's Manpower Needs , a publication
devoted to the subject of national, State, and area projections of manpower
requirements. The full series of volumes is as follows:
I Using National Manpower Data to
Develop Area Manpower Projections
II National Trends and Outlook: Industry
Employment and Occupational Structure
III National Trends and Outlook:
Occupational Employment
IV The National Industry-Occupational
Matrix and Other Manpower Data
The objective of this publication is to help fill a gap in manpower information best
described by President Johnson in his 1964 Manpower Report to Congress, “Projections
of probable need in particular occupations are an essential guide for education, training,
and other policies aimed at developing the right skills at the right time in the right
place.” Projections of occupational needs at the State and area levels are needed in
planning education and training programs. To help meet this need, Tomorrow's
Manpower Needs presents up-to-date national manpower projections and provides a
guide to their use in developing State and area manpower projections. This publication
will be used in conjunction with a companion publication, Handbook for Projecting
Manpower Requirements and Resources for States and Areas , prepared by the Bureau of
Employment Security, Manpower Administration, U.S. Department of Labor, which
will provide detailed operating instructions for the specific use of State employment
security agencies.
The assumptions underlying this publication are: (1) State and area manpower
requirements estimates can be made more reliable if the analyses are made within the
context of nationwide economic and technological developments. (2) Regional
manpower analysts familiar with local markets, the movement of industry into an area,
and other factors affecting local industry and occupational employment are best able to
estimate manpower requirements at the local level. (3) Selection of an appropriate
projection technique or mix of techniques should take into account the financial
resources available to the regional manpower analysts, the technical sophistication of
their staff, the volume of projections required, the purpose of the projections as they
affect the need for accuracy and detail, and the availability of computer assistance.
The Bureau of Labor Statistics hopes that by providing a consistent and reasonably
detailed national manpower framework and a guide to its use in making State and area
manpower projections the well-informed local analyst will be aided in developing or
improving local manpower projections.







This report was prepared in the Bureau of Labor Statistics’ Office of Manpower and
Employment Statistics. The study was performed by staff of the Bureau’s Division of
Manpower and Occupational Outlook. It was planned and supervised by Sol Swerdloff
and Russell B. Flanders. Richard E. Dempsey, David P. Lafayette, James W. Longley,
Neal H. Rosenthal, and Joe L. Russell prepared or supervised preparation of major parts
of the study. Other staff members contributing to the research and writing were liguori
O’Donnell, Melvin Fountain, Gerard Smith, Michael Crowley, Lloyd David, Penny
Friedman, Edward Ghearing, William Hahn, Jerry Kursban, Annie Lefkowitz, Dorothy
Orr, Judson Parker, Irving Phillips, Joseph Rooney, Norman Root, John Sprague,
Howard Stambler, and Annie Asensio.
The industry-occupational matrices for 1960 and 1975 were developed in the
Division of Occupational Employment Statistics, under the direction of Harry
Greenspan. The Office of Manpower Research of the Manpower Administration, U.S.
Department of Labor, funded a large part of the development of the national
industry-occupational matrix for 1975. The projections of the labor force were prepared
by Sophia Cooper Travis, Chief, Division of Labor Force Studies and by Denis F.
Johnston of that Division. The illustrative labor force projections by State presented in
the appendix were reprinted from Special Labor Force Report No. 74, prepared by
Denis F. Johnston and George F. Methee of that Division. Information on trends in
output per man-hour was provided by the Office of Productivity, Technology, and
Growth. Especially valuable was information on technological trends in major industries
collected by that office under the direction of Edgar Weinberg. In the projections of
employment by industry, extensive use was made of the work on estimates of industrial
output and employment carried on by the Division of Economic Growth, as part of the
Interagency Growth Study Project.
The Bureau wishes to acknowledge the encouragement received from the Coordi­
nating Committee on Manpower Research (CCMR) of the U.S. Department of Labor,
which recommended the development of this report. We also appreciate the assistance
of many representatives of other Federal agencies, State government agencies, private
research organizations, trade associations, labor unions, and colleges and universities.

IN TR O D U C TIO N

In a growing econom y, the occupational com position o f the work force, as well as
the skills required in each occupation, change through the years. Present manpower
needs, therefore, are an uncertain guide to future requirements. To plan education and
training programs to m eet tom orrow ’s manpower needs, projections are needed o f these
changing manpower requirements. Such projections can help also in the vocational
guidance o f young people. To the extent that education, training, and vocational
guidance accurately reflect the changing character o f manpower needs, imbalances
between manpower requirements and labor supply can be reduced, the productivity o f
the econom y and the earning power o f workers enhanced, and structural unem ploym ent
m inimized.
The manpower legislation passed in the early 1960’s emphasized the need for
projections o f occupational requirements and supply inform ation. The Area Redevelop­
ment Act o f 1961, the Manpower Developm ent and Training Act o f 1962, the
Vocational Education Act o f 1963, and the Higher Education Facilities Act o f 1963
were concerned with the education and training needs o f the Nation. Some o f these acts
specifically provided that occupational needs should be one o f the factors on which
education and training programs should be based. Other legislation, such as the
Econom ic Opportunity Act o f 1964, the Civil Rights Act o f 1964, the Higher Education
Act o f 1965, and the Appalachian Regional Developm ent Act o f 1965, focused
additional attention on the need for up-to-date information on future skill require­
ments.
Tomorrow's Manpower Needs is an attem pt to provide a basis for developing
manpower requirements inform ation for States and areas through the use o f national
manpower inform ation. The report presents the latest projections o f national manpower
requirements and provide a guide to their use in developing State and area manpower
projections. The Bureau hopes that this information will be useful also in planning
national programs o f education and training, and in reviewing the extent to which State
and local programs are meeting the N ation’s manpower needs. Specifically, the
publication provides information on the impact o f national developments on industry
and occupational manpower requirements. It presents the results o f research on the
growth and changing com position o f the population and the labor force, the relative
growth o f industries, the effect o f autom ation and other technological changes and
econom ic factors on industry em ploym ent, the occupational structure o f industries,
patterns o f working life, and techniques for appraising the supply o f workers having
various skills. This information is provided to serve as a background and tool for the
appraisal o f manpower requirements at the State and local level.
The bulletin reflects the continuing program o f manpower research conducted by the
Bureau o f Labor Statistics. Consequently, the projections o f industry and occupational
em ploym ent requirements supersede those published in previous Bureau reports. In
addition, some o f the projection data never have been published before by the Bureau in
the detail presented in this report. It is anticipated that Tomorrow's Manpower Needs
will be revised every few years to reflect the latest information available as a result o f
the Bureau’s continuing program o f manpower research.
The Bureau o f Em ploym ent Security currently is preparing a companion volum e,

Handbook for Projecting Manpower Requirements and Resources for States and Areas ,
which will explain in additional detail how analysts in State em ploym ent security
agencies can use various m ethods and sources o f data, including the national manpower
information presented in this report, to develop State and area manpower estimates and
projections.

This volume presents inform ation on the national em ploym ent trends and projected
1975 requirements for workers in nine major occupation groups and 40 selected
occupations. Volum e IV, appendix E presents em ploym ent projections for a large
number o f additional occupations. The occupational statements include a discussion o f
past em ploym ent trends, the econom ic and technological factors expected to influence
occupational requirements through the m id-1970’s, and ways workers became qualified
for the occupation.
The Bureau o f Labor Statistics, as its resources permit, may be able to provide
technical assistance, including clarification o f the m ethods described in volume I o f this
bulletin, to organizations developing State and area manpower projections. Requests for

TOMORROWS MANPOWER NEEDS: VOL. Ill
CHANG ING OCCUPATIONAL STRUCTURE

Significant changes can be expected to take place in
the occupational structure o f the N ation’s labor force.
One o f the m ost significant since World War II has been
the greater growth o f white-collar and service worker
em ploym ent, compared with that o f manual workers.
The professional and high-level managerial groups experi­
enced especially rapid growth. Em ploym ent o f whitecollar workers rose nearly two-thirds betw een 1947 and
1966, from less than 20.2 m illion to more than 33.3
m illion. Em ploym ent o f service workers also rose sub­
stantially, from 6.0 million to 9.7 m illion, an increase o f
62 percent. At the same tim e, blue-collar em ploym ent
increased much less rapidly, about 15 percent, from 23.6
m illion to 27.2 m illion, and farm workers actually
declined more than one-half, from 8.1 million in 1947 to
3.9 million in 1966.
Many factors affect the occupational structure o f the
work force. One o f the m ost important factors is the
different rates o f em ploym ent growth among industries,
resulting from influences such as shifts in incom e
distribution and changes in consum ption patterns.
Am ong the other factors are (a) growth in population
and its changing age com position, which for exam ple,
has an effect on the need for teachers; (b) government
policy, which determines such matters as the size o f
defense and space programs and expenditures for
research and developm ent; (c) institutional factors, such

as union-management relationships and practices; and
(d) supply-demand conditions, which may cause the
substitution o f workers in one occupation for more
urgently needed workers in another, such as technicians
for engineers. Another important factor that affects the
occupational structure o f the econom y is technological
change. Each industry’s occupational pattern will
continue to be heavily influenced by technological
advances, such as the developm ent o f new products and
processes and changes in the form o f business enterprise.
Taking into account these diverse factors, the projec­
tions o f occupational requirements developed for this
report anticipate about a 28 percent increase in whitecollar workers betw een 1966 and 19 75 .1 (See table 1.)
Among white-collar occupations, the m ost rapid advance
in requirements will be for professional and technical
workers, who may increase nearly twice as fast (39
percent) as the average for all workers (20 percent).
Requirements for both clerical workers and sales
workers also are expected to increase rapidly, about
one-fourth, and the need for managers, officials, and
proprietors should rise more than one-fifth. Require­
m ents for blue-collar workers are expected to rise 10
percent betw een 1966 and 1975. Among blue-collar
workers, the m ost rapid increase in requirements will be
for craftsmen (18 percent), about the average increase
for total em ploym ent. Requirements for operatives will
increase more slowly (7 percent), and little change is

Replacement Needs
In addition to anticipated manpower needs for
occupational growth, m any hundreds o f thousands o f
workers will be required to replace those who are
expected to withdraw from the labor force because o f
deaths, retirem ents, or for other reasons. Each year such
losses are estim ated at about 3 percent o f all workers.
The loss rate to a specific occupational group is
influenced heavily by the age and sex distribution o f its
workers. For exam ple, replacement needs for wom en
workers are high because m any young w om en leave the
labor force each year to get married and rear families.
Thus, the major occupational groups with the highest
proportion o f fem ales—clerical and service workers—have
the highest loss rates (3.5 percent to 4.5 percent
annually); the major occupational groups with the
low est proportion o f fem ales—laborers and craftsmen—
have the low est loss rates (1.5 percent to 2.0 percent
annually).

Training
Workers in the United States acquire the education
and training necessary to perform their jobs through a
variety o f m ethods. O f those holding white-collar jobs,
professional, technical, and kindred workers generally
acquire their occupational training in a 4-year college or
university. Large numbers o f professional and related
4




workers com plete 2 years o f post-secondary training in a
junior college, technical institute, or specialized school.
In some technical occupations such as engineering and
science technicians, on-the-job training provided by
em ployers has been the primary m ethod o f obtaining the
needed training. Four-year college programs prepare
large numbers o f managerial workers for their jobs.
However, many o f these workers also qualify through
experience in related sales or clerical jobs. Clerical
workers, the largest o f the white-collar occupational
groups, generally com plete high school business courses,
or post-secondary training in business schools and in
junior colleges. Sales workers who sell com plex products
such as scientific instruments or industrial machinery
may acquire their training in a college or university,
supplem ented by specialized training given by their
em ployers. Other sales workers who sell standardized
merchandise in retail stores generally have little speciali­
zation; they usually learn their duties on the job in a
short tim e.
Among blue-collar workers, craftsmen receive inten­
sive training to qualify for their jobs—many o f them
through apprenticeship or other formal training pro­
grams given on the job, som etim es supplem ented by
related classroom instruction. Many craftsmen, however,
acquire knowledge needed to perform their jobs through
work experience by moving from one semiskilled job to
another over a period o f years. Semiskilled workers

(operatives) generally acquire their training on the job;
this training may last from a few days to several weeks
and generally is inform al, w ith the supervisor providing
necessary instruction. Laborers usually require no
specialized training, other than brief instructions.
Service workers are a very diverse group and acquire
their training in a variety o f ways. The am ount o f
training needed by these workers ranges from a college
education, as for FBI agents, to short on-the-job training
for elevator operators. Many service workers, such as
barbers and cosm etologists, attend vocational school.
For the m ost part, farm workers learn their work on
the job. Others take vocational training, such as that




available under federally assisted programs; and still
others, including farm owners and managers, are grad­
uates o f college programs in agriculture.
Inform ation on the m ethods through which workers
are trained for their jobs m ust be viewed carefully in
analyzing a particular area’s manpower situation.
Employers in the designated area may prefer workers
trained in a manner that differs from the m ethods
generally used in other parts o f the country. Therefore,
in developing training programs for given occupations or
groups o f related occupations, planners must consider all
training m ethods already in effect for the occupations in
the selected areas.

PROFESSIONAL, TEC H N IC A L, AND K IN D R E D WORKERS

Current Employm ent
About 9.3 m illion workers were em ployed in profes­
sional, technical, and kindred occupations in 1966. The
largest groups o f these workers were teachers (more than
2 m illion); professional health workers (about 2 m illion);
scientists and engineers (about 1.4 million); and
engineering and science technicians, including draftsmen,
(about 900,000).

Training
Professional and technical workers generally require
extensive education and training. Professional workers
usually acquire their specialized knowledge in a college
or university; m ost o f them need a bachelor’s degree to
enter their occupations. Others—including physicians,
dentists, and architects—m ust com plete more than 4
years o f college to qualify for their professions. Tech­
nical workers, such as draftsmen and engineering and
science technicians, may com plete 2 years o f post­
secondary training in a junior college, technical institute,
or specialized school.
Som e professional and technical workers qualify for
their jobs through on-the-job training, rather than formal
schooling. The length o f this training varies for different
occupations. For exam ple, many medical laboratory
assistants com plete several m onths o f on-the-job
training, whereas, many engineering technicians have had
several years o f on-the-job training and experience. The
importance o f industry training for engineering tech­
nicians is described in a Bureau o f Labor Statistics
stu d y2 which states that in recent years one-fourth o f
the new entrants to the technician group qualified
through formal industry training and one-half qualified
through informal on-the-job training or were upgraded
from lesser skilled jobs.
Licenses or certificates are required for work in many
professions that affect the health, safety, or welfare o f
the general public, such as m edicine, dentistry,
pharmacy, architecture, and teaching. Generally, the
licensing requirements specify the com pletion o f a
recognized training program and the passing o f an
exam ination given by a State examining board.

Em ploym ent Trends and Outlook
Em ploym ent o f professional, technical, and kindred
workers increased nearly 2>h betw een 1947 and 1966,
6




rising from about 3.8 m illion to 9.3 m illion. This
increase was stim ulated by a growing demand for goods
and services resulting from population growth and rising
business and personal incom es. Other factors underlying
this em ploym ent growth included increasing government
and private expenditures for research and developm ent,
highways, public buildings, medical care, education, and
a great variety o f other goods and services.
By 1975, manpower requirements for professional,
technical, and kindred workers are expected to rise
nearly 40 percent to 12.9 m illion. Manpower needs will
increase in practically every professional and technical
f ie ld —including counseling, the natural sciences,
engineering, programing, the health professions, the
social sciences, social and welfare work, and teaching—
but the rate o f increase is likely to differ among the
occupations.
Teaching, the largest profession, is expected to grow
m oderately to m eet the needs o f a rising school-age
population and an expected increase in school
attendance. The demand for elementary and secondary
school teachers is expected to increase more slowly than
for college and university teachers.
In engineering and natural science occupations,
em ploym ent requirements are expected to increase
substantially by 1975. Increased requirements are antici­
pated to m eet the general needs o f our increasingly
com plex and technologically oriented econom y and the
N ation’s expanding research and developm ent programs.
Em ploym ent requirements for scientists are expected to
grow faster than those for engineers.
E m ploym ent requirements for technicians are
expected to grow very rapidly from 1966-75. The
increasing emphasis on improved utilization o f workers
such as scientists, engineers, physicians, and dentists and
the need to relieve these workers o f relatively routine
tasks that can be performed by less highly trained
persons will continue to be the major factors that
underlie the increased requirements for technicians.
Em ploym ent requirements in health service occupa­
tions also are expected to increase substantially. Among
the factors underlying this expected increase are popula­
tion growth and the increasing ability o f persons to pay
for health care, growing interest in preventive m edicine,
and an increase in medical research to prevent diseases.

Technician Manpower: Requirements, Resources, and
Training N eeds (BLS Bulletin 1512, June 1966).

In addition to manpower needs for occupational
growth, many professional, technical, and kindred
workers will be needed to replace those who transfer to
other fields of work, or who die, retire, or otherwise

withdraw from the labor force. For example, each year,
an estimated 2.5 to 3.0 percent of the workers in this
occupational group withdraw from the labor force.

Accountants3

Current E m ploym en t

About 500,000 accountants were employed in 1966.
About 80,000 of these workers were certified public
accountants (CJP.A.’s).
More than half of all accountants do private account­
ing work for business and industrial firms. About
one-third are engaged in public accounting as pro­
prietors, partners, or employees of independent
accounting firms. About 10 percent work for Federal,
State, and local government agencies. A small number
teach in colleges and universities.
Training

Accountants acquire the training needed to perform
their work in a variety of ways. A large number qualify
by completing 4-year college degree programs and
receiving a major in accounting or a closely related field.
Many others acquire their accounting skills in 2- or
3-year programs in private accounting or private business
schools. Some acquire their skills in junior college
courses or through correspondence courses.
All States require that anyone practicing in the State
as a CJP.A. hold a certificate issued by the State board of
accountancy. Requirements for licensing and registration
vary from one State to another. Almost half the States
have laws that by 1970, will require C.P.A. candidates to
be college graduates. All States use the C.P.A. examina­
tion provided by the American Institute of Certified
Public Accountants. Nearly all States require at least 2
years of public accounting experience, or its equivalent,
before the C.P.A. certificate is used.
E m ploym en t Trends and O utlook

Employment of accountants increased from more
than 300,000 in 1950 to about 500,000 in 1966. This
increase resulted from a number of factors, including
growth in the size and number of businesses; greater use




of accounting procedures in business management;
increased complexity and changes in tax systems; and
increased use of accounting services by small businesses.
Employment requirements for accountants are
expected to rise about one-third between 1966 and
1975, from 500,000 to about 660,000 based, in part,
upon a continuation of the factors operating in the past.
In addition, several new developments are expected to
stimulate the demand. For example, growth in the
number and activities of nonprofit institutions—
including charitable, health, and welfare organizations;
pension and welfare funds; labor unions; educational
institutions; churches; and clubs— result in more
may
financial reporting and the need for more accountants.
The computer is expected to have a major effect on
the accounting profession in the future. The increasing
use of automatic data processing systems is expected to
reduce manual bookkeeping for preparing trial balances,
financial statements, and simple tax returns. As a result,
the need for junior accountants may be reduced substan­
tially. On the other hand, computers provide vast
quantities of accounting data that will require additional
accountants to analyze. In larger companies, the com­
puter is expected to bring about radical changes in
information systems and decisionary processes. As the
number of “total” information systems rise, additional
highly trained accountants will be required to prepare,
administer, and analyze the output of these systems.
In addition to the number of accountants that will be
needed from 1966-75 to meet the growth in manpower
requirements, many will be needed to replace those who
retire, die, or otherwise withdraw from the labor force,
or who transfer to other fields of work. For example,
each year, withdrawals from the labor force alone are
estimated to number between 2.0 to 2.5 percent of all
accountants.

Chemists4

Current E m ploym en t

Nearly 120,000 chemists were employed in 1966;
chemists constituted the largest group of physical
scientists.5 This occupational classification includes five
specialists: organic chemists, inorganic chemists, physical
chemists, analytical chemists, and biochemists. About
two-thirds of all chemists work for private industry. The
major industrial employer of chemists, the chemicals
manufacturing industry, employs more than two-fifths
of the chemists in private industry. Relatively large
numbers of chemists also are found in the industries
manufacturing food, petroleum, paper, electrical equip­
ment, and primary metal products. Significant numbers
of chemists also are employed by distributors of
chemical, pharmaceutical, food, and petroleum pro­
ducts, and by independent laboratories and research
institutes providing consulting services. About one-fifth
of all chemists are employed in colleges and universities.
A smaller number of research chemists work for founda­
tions and other nonprofit organizations. Others are
employed by Federal Government agencies; small
numbers work for State and local governments.
Training

Most chemists acquire their basic professional training
in college and university programs leading to the
bachelor’s degree in chemistry. Other chemists qualify
for their jobs through other basic science or engineering
programs. In addition, some technicians without degrees
enter chemist jobs after acquiring the required knowl­
edge through many years of work experience.
According to a follow-up study of the career patterns
of new college graduates6 about one-third of each year’s
college graduates who receive the bachelor’s degree in
chemistry enter chemistry jobs. Other graduates with the
chemistry degree enter other science occupations or
engineering, or take jobs in fields such as sales or
management. However, some of those who enter other
types of jobs eventually return to chemistry.
E m ploym en t Trends and O utlook

Employment of chemists increased from more than
50,000 in 1950 to nearly 120,000 in 1966. One of the

8




major factors underlying this rapid increase was the
sharp growth in demand for products of industries that
employ large numbers of chemists, particularly the
chemicals and allied products industry. Increased
expenditures for research and development, in which
nearly one-half of all chemists are engaged, was another
major factor in the employment growth of chemists. In
addition, scientific discoveries opened new employment
areas for chemists in manufacturing products such as
plastics, man-made fibers, rocket fuels, and
pharmaceuticals.
Employment requirements for chemists are expected
to rise by more than three-fifths between 1966 and
1975, from nearly 120,000 to about 195,000. An
important reason for the anticipated increased demand
for chemists will be growing expenditures for research
and development. Such expenditures, which have
increased rapidly in recent years, probably will continue
to rise through the mid-1970’s, although somewhat more
slowly than in the past 10 years. Other important
reasons for the expected rise in employment require­
ments for chemists include the expanding demand for
the products of industries that are major employers of
chemists, the greater complexity of chemical products
and the processes required to produce them, and the
increased demands of a growing population for improved
products, such as better drugs.
In addition to those chemists needed over the
1966-75 period to meet rising employment require­
ments, many will be needed to replace those who
transfer to other occupations or withdraw from the
labor force because of death, retirement, or other
reasons. Annual losses for these reasons are estimated at
3.0 to 4.0 percent of all chemists.

for chemists presented here differ from those in Vol. IV,

teachers. The occupation-industry matrix follows the Census

Draftsmen7

Current E m ploym en t

About 260,000 draftsmen were employed in 1966.
The large majority—
nearly 9 out of 10— employed in
are
private industry. The manufacturing industries that
employ large numbers of draftsmen are the machinery,
electrical equipment, fabricated metal products, and
transportation equipment industries. Nonmanufacturing
industries employing large numbers of draftsmen are
engineering and architectural consulting firms, construc­
tion companies, and public utilities.
More than 25,000 draftsmen worked for Federal,
State, and local governments in 1966. Of those
employed by the Federal Government most work for
the Departments of Army, Navy, and Air Force.
Draftsmen employed by State and local governments
work chiefly for highway and public works departments.
A few thousand draftsmen are employed by colleges and
universities and by nonprofit organizations.
Training

Draftsmen acquire their training in a variety of ways.
Many complete training programs in technical institutes,
junior and community colleges, and vocational and
technical high schools. Others acquire their training on
the job, while they attend part-time schooling in colleges
and universities or correspondence schools, or in 3-or
4-year apprenticeship programs.

1950 and 1966. The rapid growth in demand for the
products of the durable goods industries, which employ
large numbers of draftsmen, was a major factor under­
lying this increase. Another contributing factor was the
large increase in the number of complex products
requiring extensive plans and exact drawings to be
produced. In addition, the rapid growth in areas of work
requiring large numbers of draftsmen— as research
such
and development, space exploration, and defense
activities—
contributed greatly to the increase in employ­
ment from 1950 to 1966.
Employment requirements for draftsmen are
expected to increase about 45 percent between 1966
and 1975, and rise to about 375,000. However, this
projected increase represents a significant reduction in
the rate of increase over the past decade and a half.
Among the factors underlying the projected growth are
the continued expansion of industries employing large
numbers of draftsmen, and the increasingly complex
design problems of modern products and processes.
Furthermore, as the number of scientists and engineers
increases, more draftsmen will be needed as support
personnel.
In addition to draftsmen needed to fill new positions
from 1966-75, many will be required to replace those
who transfer to other fields of v/ork, or who die, retire,
or otherwise leave the labor force. Annual replacements
are estimated at 4.0 to 5.0 percent of all draftsmen.

Engineering and Science Technicians8

Curren t E m ploym en t

Nearly 650,000 engineering and science technicians
(excluding draftsmen and surveyors) were employed in
1966. Engineering technicians make up the largest field
of specialization, and account for more than half of all
technicians. Physical science technicians, about half of
whom were chemical technicians, constituted more than
one-fifth of the total. The next largest group was made
up of life science technicians, who averaged about 10
percent of all technicians.
About three-fourths of all technicians were employed
by private industry in 1966. The industries employing




the largest number of technicians were electrical equip­
ment, chemicals, machinery, and aircraft and parts. The
Federal Government employed more than 70,000
engineering and science technicians, mainly in the
Department of Defense. State government agencies
employed about 45,000, and local governments over
15,000. The rest were employed by colleges and
universities, mostly in university-operated research insti­
tutes, and by nonprofit organizations

Engineers9

Current E m ploym en t

About 1 million engineers were employed in 1966.
Engineering is the second largest profession and for men,
it was the largest profession.10 Three fields of specializa­
tion-electrical, mechanical, and civil engineering—
each
accounted for about 20 percent of all engineers. Smaller
proportions were employed in industrial (11 percent),
aeronautical (6 percent), and chemical (5 percent)
engineering. The rest were employed in several other
specialties, including sales, agricultural, ceramic, metal­
lurgical, and mining engineering.
More than one-half of all engineers were employed in
manufacturing in 1966. The manufacturing industries

neering and architectural services; and electric, gas, and
sanitary services industries. About 15 percent of all
engineers were employed in Federal, State, and local
government agencies other than educational institutions.
More than half of these engineers worked for the Federal
Government. Public and private educational institutions
employed about 3.5 percent of all engineers.
Training

An estimated 70 percent of all engineers employed in
1966 had an engineering degree. About 10 percent had a
college degree in one of the natural sciences, and a very
small proportion had a degree in a field other than
science or engineering. The rest, nearly one-fifth, who
did not have a degree, qualified after many years of
experience in a related occupation such as engineering
technician or draftsman. According to a follow up study
of career patterns of new college graduates,11 about 85
percent of each year’s college graduates who receive the
bachelor’s degree in engineering enter engineering jobs.
Other graduates enter natural science or sales occupa­
tions, or nontechnical work such as management. How­
ever, some of those who enter other types of jobs
eventually return to engineering.
All 50 States and the District of Columbia have laws
which license or register engineers whose work may
affect life, health, or property. Generally, registration
requirements include graduation from an accredited
college, plus at least 4 years of experience in engineering
work and the passing of a State examination. Examining
boards may accept a longer period of experience as a
substitute for a college degree.
E m ploym en t Trends and O utlook

Rising from more than 400,000 to about 1 million,
engineering was one of the fastest growing occupations
between 1950 and 1966. A major factor in this increase

was the rapid growth of industries employing large
numbers of engineers. The rapid growth of Federal,
expenditures for research and development and defense
and defense-related activities resulted in large increases
in employment, particularly in the aircraft and parts,
electrical machinery, professional and scientific instru­
ments, and ordnance industries. Many scientific
discoveries developed new areas of work for engineers,
including nuclear energy, space exploration, and
computer technology.
Engineers are expected to number nearly 1.5 million
in 1975 largely because of the anticipated growth of
industries employing large numbers of engineers and
increasing research and development activities. Expendi­
tures for such activities are expected to rise through the
mid-1970’s, although the rate of growth will be less
rapid than in the recent past. Engineers will continue to
be in the forefront of technological change, and the
growing automation of industry will require large
numbers of engineers to plan, develop, and produce the
equipment involved.
This report assumes that the level of defense expendi­
tures in 1975 will not be significantly different from
that in 1964. Therefore, rising levels of defense expendi­
tures were not significant in projecting the large increase
in requirements for engineers. A major change in defense
activity would affect requirements for engineers, since
an estimated one-fourth of all engineers are engaged in
defense or related activities.
In addition to the number of engineers needed from
1966-75 to meet the growth in manpower requirements,
many thousands will be needed to replace those who
transfer to other fields of work, or who die, retire, or
withdraw from the labor force for other reasons.
Approximately 2.5 to 3.5 percent of all employed
engineers must be replaced each year.

Registered Professional Nurses 12

Current E m ploym en t

Nursing is the largest profession in the health field. In
1966, more than 620,000 registered professional nurses
were employed in the United States; about one-fourth
worked part-time.
Approximately two-thirds of all nurses worked in
hospitals and related institutions. About 10 percent were




private duty nurses who cared for patients in hospitals
and private homes, and about 8 percent were office
nurses. Public health nurses in government agencies,
visiting nurse associations, and clinics made up approxi­
mately 6 percent; nurse educators in nursing schools

accounted for 4 percent; and occupational health nurses
in industry, about 3 percent.
Training

Professional nurses acquire the training through three
types of educational programs—
diploma, baccalaureate
degree, and associate degree. In 1966, about threefourths of all graduates of these programs completed
diploma programs, which are conducted by hospital and
independent schools and usually require 3 years of
training. About 15 percent completed bachelor’s degree
programs, some of which require 5 years of study.
About 10 percent of all nursing program graduates were
trained in associate degree programs in junior and
community colleges.
The large majority— out of every 8— all profes­
7
of
sional nurses employed in 1966 had a diploma or
associate degree. More than 10 percent had a baccalau­
reate degree, and the rest had a master’s or higher
degree.
A license is required to practice professional nursing
in all States and in the District of Columbia. To obtain a
license, a nurse must graduate from a school approved
by a State board of nursing and pass a State board
examination. A nurse may be licensed in more than one
State, either by examination or endorsement of a license
issued by another State.
E m plo ym en t Trends and O utlook

Rising from 375,000 to more than 620,000, employ­
ment of nurses increased about two-thirds between 1950

and 1966. The major growth factors included increased
demand for hospital and other medical and health
services resulting from the expanding population; exten­
sion of medical insurance coverage; growing expendi­
tures by industry and government for medical care; and
rising standards of living.
Employment requirements for nurses are expected to
rise about two-fifths between 1966 and 1975, to about
860,000. Among the factors that are expected to
contribute to a continuing increase in demand for
hospital and health services and, therefore, an increasing
need for nurses are: a growing population; rising ability
of families to pay for medical care, partly because of
greater coverage of insurance programs, including
Medicare; and expansion of medical services resulting
from new medical techniques and drugs. An increasing
number of nurses also will be needed to rehabilitate the
mentally handicapped, particularly in community health
centers being established under the provisions of the
Mental Retardation Facilities and Community Health
Centers Construction Act of 1963.
In addition to manpower requirements for employ­
ment growth through the mid-1970’s, many nurses will
be needed to replace those who transfer to other fields
of work or who die, retire, or leave the labor for
marriage or other family responsibilities or for other
reasons. Each year the profession loses approximately
4.5 to 5.0 percent of its nurses. Many who become
inactive because of home responsibilities, however,
return to the profession in later years.

Training

Teachers make up the largest group of professional
workers. About 2.2 million full-time teachers were
employed in the 1965-66 academic year. Approximately
one-half of all teachers were employed in elementary
schools, more than a third in a secondary school, and
about 10 percent in colleges and universities.
Women teachers far outnumber men in kindergarden
and elementary schools and hold slightly less than
one-half of the teaching positions in secondary (junior
and senior high) schools. However, only about onefourth of all college and university teaching positions are
filled by women.

All States require elementary and secondary school
teachers in public schools to have a teaching certificate.
In 1966, 46 States and the District of Columbia issued
regular elementary school teaching certificates only to
persons who have at least 4 years of approved college
preparation. In every State, a bachelor’s degree is needed
for a secondary school teaching certificate. For both
elementary and secondary school certificates, most

Labor, 1966, 3d edition.

States also require at least the equivalent of one-half
year of education courses.
In 1966, more than one-fifth of all recipients of
bachelor’s degrees met the certificate requirements for
high school teaching. Nearly 15 percent met the certifi­
cate requirements for elementary school teaching. How­
ever, all those who have teaching certificates do not
enter teaching. In 1966, about 4 of every 5 who met the
requirements for an elementary school teaching certifi­
cate entered elementary school teaching positions and
about two-thirds of those who met the requirements for
a high school teaching certificate entered high school
teaching positions.
Of all new college teachers in the 1965-66 academic
year, about 27 percent had a doctor’s degree. About 60
percent had a master’s degree and about 13 percent had
a bachelor’s degree.
Employment Trends and Outlook
Employment of public and private school teachers
combined increased from an estimated 1.4 million in the
1955-56 school year to about 2.2 million in 1965-66.
This employment growth resulted primarily from a great
increase in the school-age population. In addition, the
proportion of young people of high school and college
age attending school has increased in recent years. At the
beginning of the 1965-66 school year, about 54 million
people were enrolled in the Nation’s schools and
colleges, compared with about 38 million people in the
1955-56 school year.
Employment requirements for teachers are expected
to rise more than one-fifth during 1966-75 and reach
about 2.7 million in 1975-76 because of increases in the
growth of the school-age population, increasing at­
tendance rates, and improvement in the pupil-teacher
ratios. At the elementary school level increasing requireMedical Labor*

ments will result primarily from improvement in the
pupil-teacher ratio. A slight decline of enrollments is
expected because of declines in the school-age popula­
tion and because attendance rates already are high.
Secondary school and college enrollments are
expected to increase 30 percent and 65 percent respec­
tively, partly because the school-age population at these
levels is expected to increase. Attendance rates also
should rise as part-time work becomes increasingly
available to high-school and college students; as the
financial ability of parents to pay for higher education
increases; and as scholarships become more numerous
for college and university students, in part due to funds
provided by recent Federal legislation, including the
Health Profession Educational Assistance Act of 1963
and the Higher Education Act 1965. Growth of facilities
to accommodate the increasing number of students also
will result from these acts as well as from the Elemen­
tary and Secondary Education Act of 1965 and the
Amendments to these acts.
Technological developments will have little effect on
employment requirements for teachers through the
mid-1970’s. Educational television and teaching
machines are gaining in use, but they will have little
influence on reducing the need for teachers. Such
equipment probably will be used primarily to free
teachers from routine tasks; to provide time for indi­
vidual assistance to students; and to prepare improved
lessons and teaching materials.
In addition to manpower needs for occupational
growth, many teachers will be needed to replace those
who transfer to other occupations, die, retire, or leave
the field for family responsibilities. Many teachers who
become inactive because of family responsibilities, how­
ever, return to the profession in later years. Each year
the profession has a estimated net loss of between 6.0
and 8.0 percent of all employed teachers.

in a medical laboratory. Such training usually lasts about
one year, but the length of time may vary, depending on
the person’s previous experience and his ability to
master laboratory techniques.
An increasing number of medical laboratory assistants
are acquiring their skills in academic programs offered
by hospitals and by private schools. These programs last
a year and include classroom instruction and practical
training in the laboratory. Hospitals provide the greatest
number of such programs, many of which were estab­
lished in recent years under the Manpower Development
and Training Act of 1962 and the Vocational Education
Act of 1963. A few medical laboratory assistants acquire
their training in 2-year programs offered by junior
colleges.
Employment Trends and Outlook
The employment of medical laboratory assistants rose
from about 20,000 in 1950 to approximately 50,000 in
1966. Among the factors underlying this rapid employ­
ment growth were an increase in the number of
hospitals, growth of medical care insurance programs, an
increasing population, and the development of new
laboratory techniques and laboratory tests to diagnose
and treat disease.
Employment requirements for medical laboratory
assistants are expected to reach 100,000 in 1975, double
the 1966 levels. The factors that contribute to this

14




anticipated continuing rapid growth include the
country’s expanding population; increasing ability of
persons to pay for health care, partly because of the
expansion of prepayment programs for hospitalization
and medical care, including Medicare; expanding medical
services resulting from new medical techniques and
drugs; increasing reliance of physicians on laboratory
tests to diagnose and treat disease; expanding medical
research activities; and increasing use of assistants
relative to other more highly trained laboratory workers.
Federal legislation is expected to be a major factor
stimulating the demand for medical laboratory as­
sistants, as well as for all other health workers. Examples
of such legislation recently passed by Congress include
Medicare and Medicaid in the Social Security Amend­
ments of 1965; the Heart Disease, Cancer, and Stroke
Amendments of 1965; and the Mental Retardation
Facilities and Community Health Centers Construction
Act of 1965 as amended.
In addition to the employment requirements for
occupational growth, many assistants will be needed
from 1966-75 to replace workers who transfer to other
occupations, or who die, retire, or withdraw from the
labor force for other reasons. Each year, withdrawals

the field for marriage or family responsibilities) are

MANAGERS, O FFIC IA LS , AND PROPRIETORS

Current Employment
About 7.4 million managers, officials, and proprietors
were employed in the United States in 1966; about
two-fifths were self-employed. Women constituted about
15 percent of this occupational category.
Managers are employed in virtually all industries.
Retail trade was the largest employing industry, and
accounted for about one-third of all managers, officials,
and proprietors in 1966. Other industries which had
large numbers of managers were durable and nondurable
goods manufacturing; wholesale trade; finance, in­
surance, and real estate; construction; and public admin­
istration .
Training
Managers, officials, and proprietors acquire training
for their jobs in a variety of ways. Large numbers of
salaried managers have completed a bachelor’s degree
program in business administration and received a major
in accounting, economics, or finance. Others have
backgrounds in engineering, science, or liberal arts. Many
managers who have less than a bachelor’s degree quali­
fied for their positions through experience in related
work in sales and clerical jobs.
Many large organizations place beginners in manage­
ment trainee programs that may last a year or more.
Such programs often include job rotation and formal
classroom instruction, and help prospective managers
and officials become acquainted with the organization’s
activities and policies as well as with specific job
functions.
Employment Trends and Outlook
Employment of managers, officials, and proprietors
increased from nearly 5.8 million to 7.4 million between
1947 and 1966. However, employment trends among
the occupations that make up this broad occupational
category varied sharply.
Employment of salaried managers and officials,
including industrial traffic managers and purchasing
agents, rose rapidly between 1957 and 1966 and grew
from about 3 million to about 4.7 million. Major reasons
for this increase were the continuing growth in the size
of business and manufacturing establishments and the
ever increasing complexity of a wide variety of business
functions. Technological developments also contributed
to the employment growth, and were reflected in the




increasing number of technical managers needed to plan
research and development programs, make policy
decisions concerning the installation and use of auto­
mated machinery, and supervise automatic data proces­
sing systems.
The number of proprietors, on the other hand,
declined during 1957-66, from about 3.7 million to
about 2.7 million largely because of the replacement of
small grocery and general stores and hand laundries
(often run as family businesses) by supermarkets and
large chains. Also, many proprietors of relatively small
firms incorporated their businesses and thereby became
classified as “salaried managers” instead of “selfemployed.”
Employment requirements for managers, officials,
and proprietors as a group are expected to rise more
than one-fifth between 1966 and 1975, increasing from
7.4 million to 9.0 million. The major reasons for this
anticipated growth include the expected continued
increase in demand for goods and services resulting from
a growing population and rising living standards, and the
continued increase in the number and complexity of
business establishments. As in the past, requirements for
salaried managers and officials are likely to continue to
increase rapidly because of the increasing dependence of
business organizations and government agencies on
trained management specialists.
The number of self-employed managers is expected to
continue to decline from 1966-75. The trend toward
formation of larger businesses is expected to continue to
restrict the growth in the total number of firms. In
addition, the replacement of small grocery and general
stores and hand laundries by supermarkets and large
chains is expected to continue. However, the greatest
part of this shift from small proprietor-owned stores to
larger businesses appears already to have taken place
and, as a result, the decline in the number of proprietors
is expected to be slower through the mid-1970’s than
over the past decade. This decline also will be limited by
the expansion of such businesses as quick-service grocery
stores, self-service laundries and drycleaning shops,
hamburger and frozen custard drive-ins, dance studios,
and slenderizing salons.
In addition to the number of managers required for
employment growth from 1966-75, many will be needed
to replace managers who transfer to other occupations,
or who withdraw from the labor force because of death,
retirement, or other reasons. For example, each year an
estimated 2.5 to 3.0 percent of all managers, officials,
and proprietors withdraw from the labor force.

Bookkeeping Workers 15

Current Employment
About 1.2 million workers were employed in book­
keeping jobs in 1966. Five of every six of these workers
were women and most are general bookkeepers or
accounting clerks. Bookkeeping machine operators
probably number fewer than 75,000.
Bookkeeping workers are found in all industries. In
1966, about 25 percent were employed by retail
establishments and almost 20 percent by manufacturing
16




firms. Banking and credit agencies employed more than
12 percent, and wholesale trade establishments, over 10
percent.
Training
Bookkeepers often obtain preliminary training in
high school courses, such as business arithmetic and
15 (D.O.T. 210.368 through .588; 215.388 and .488;
216.388; and 219.388 and .488), Dictionary o f Occupational
Titles , U.S. Department of Labor, 1966, 3d edition.

bookkeeping, through post-high school business courses,
or in junior colleges. Most bookkeeping workers, how­
ever, acquire their skills on the job. An increasing
number of large companies offer on-the-job training for
newly hired accounting clerks and machine operators. In
some localities, employers cooperate in work-study
programs operated by high schools and business schools
in which students gain practical work experience. Some
bookkeepers have received training through programs
established under the Manpower Development and
Training Act of 1962. In 1966, about 1,100 persons
were enrolled in MDTA institutional programs for
bookkeeping workers.
Employment Trends and Outlook
Employment of bookkeeping workers increased from
about 725,000 in 1950 to about 1.2 million in 1966, or
by about two-thirds. This increase resulted primarily
from expansion of economic activity and growth in the
complexity of modem business.
Employment requirements for bookkeeping workers
are expected to increase to nearly 1.4 million in 1975,
about one-sixth above the 1966 level. The increasing use
of laborsaving technological innovations, such as auto­

matic data-processing and other mechanized book­
keeping equipment, however, will limit the growth of
workers performing the more routine bookkeeping tasks.
More and more accounting and bookkeeping establish­
ments will use electronic data processing machines.
However, many companies probably will not have the
capital nor the volume of work to automate their
bookkeeping operations. Furthermore, some firms will
continue to combine electronic data-processing equip­
ment with conventional equipment. Even in companies
that install electronic data processing equipment, book­
keepers who did routine clerical posting before the
machines were installed are not expected to be displaced
to any great extent. The bookkeeping demands of many
firms will continue to grow and create an increasing need
for workers to prepare the inputs for the new equipment
and the additional reports made possible by using this
equipment.
In addition to manpower needs for occupational
growth, many bookkeeping workers will be needed to
replace workers who transfer to other occupations, or
who withdraw from the labor force because of death,
retirement, or other reasons. Each year withdrawals
from the labor force alone are estimated to be between
4.0 and 4.5 percent of all bookkeeping workers.

Office Machine Operators 16

Current Employment
About 500,000 office machine operators (excluding
typists) were employed in 1966 most of whom were
women.
About one-third of all office machine operators work
for manufacturing companies. Other large numbers work
for banks and insurance companies, government
agencies, wholesale and retail firms, and transportation
and public utility companies. Some office machine
operators are employed in “service centers,” agencies
that contract to handle tasks such as preparing monthly
bills and mailing circulars.
Training
Most office machine operators learn their skills
mainly on the job. Although some receive high school or
business school training in business arithmetic and the
operation of office machines, additional on-the-job
training is usually necessary. Also, some office machine
operators have received training through programs
operated under the Manpower Development and
Training Act of 1962.




The amount of instruction and on-the-job experience
needed by new workers depends chiefly on the type of
machine or machines they operate. Only a few days may
be required to train operators of some duplicating
machines; a few weeks may be needed to train key­
punch and calculating machine operators. Several weeks
are required for operators of tabulating machines to
learn how to set and adjust their equipment and to do
simple wiring of plugboards. Operators of tabulating
equipment often are trained at company expense in
special schools established by equipment manufacturers.
Computer operators may acquire some of their
training in high school, business school, or a school run
by computer equipment manufacturers, and complete
their training on the job. Auxiliary equipment operators
generally learn their skills in a few weeks on the job.
Console operators receive most of their training through
formal classroom instruction, where they learn how to

mount tapes, operate the console, and become suffi­
ciently familiar with the equipment they are using to
trace the reasons for mechanical failures. This training is
supplemented by further instruction on the job.
Employment Trends and Outlook
Employment of office machine operators increased
from more than 140,000 in 1950 to about 500,000 in
1966 because of a tremendous increase in the paper
work requirements of an expanding economy, and
growth in the size and complexity of modern business.
The expanding use of electronic computers resulted in a
rapid increase in the employment of operators of
computers and auxiliary equipment.
Employment requirements for office machine
operators are expected to increase nearly two-fifths
between 1966 and 1975, to approximately 700,000
workers. Underlying this projected increase is the
expected continued growth of recordkeeping require­
ments in both the public and private sectors of the
economy. Large employers of office machine operators
such as manufacturing, insurance, and banking firms are
expected to experience significant increases in paper­
work volume, as their business continues to grow.
Although employment requirements for office
machine operators as a whole will increase rapidly in the
years ahead, technological developments are expected to
limit growth in employment requirements for operators
of certain types of office machines. The spread of

automated recordkeeping processes may displace some
tabulating and billing machine operators, since electronic
computers generally perform these functions more effi­
ciently. In addition, as automatic reading devices
become a common component of computer systems,
requirements for keypunch operators to prepare material
for use in computers may be affected adversely. Further­
more, advances in interoffice communications and elec­
tronic computer technology should enable many large
private firms and government agencies to consolidate
recordkeeping functions at a central location, and reduce
requirements for office machine operators in many small
branch offices. As more sophisticated computer systems
are introduced in the future, the number of computer
and auxiliary equipment operators needed for each
machine may decline. However, the spread of computer
service centers, along with the increased applications of
computers to more varied functions, should result in a
rapid increase in the employment of computer operating
personnel.
The increasing use of “quick-copy” equipment and
other new and improved office machines also is expected
to stimulate the demand for office machine operators.
In addition to manpower needs for occupational
growth, many office machine operators will be needed
to replace workers who transfer to other occupations, or
who die, retire, or withdraw from the labor force for
other reasons during 1966-75. For example, each year,
withdrawals from the labor force alone are estimated to
be between 3.5 and 4.0 percent of all office machine
operators.

Some secretaries and stenographers obtain their skills
in bachelor’s degree programs in secretarial studies
offered in colleges and universities. Others train in
programs established under the Manpower Development
and Training Act of 1962. In 1966, about 8,700 persons
were enrolled in MDTA institutional programs for
secretaries, stenographers, and typists.
Employment Trends and Outlook
Rising from nearly 1.6 million to about 3.1 million,
employment of stenographers, secretaries, and typists
increased nearly double between 1950 and 1966. Expan­
sion of economic activity and growth in the complexity
of modern business tended to increase the volume of
paperwork and, thus, employment requirements for
these workers.
Employment requirements for stenographers, secre­
taries, and typists are expected to increase more than
one-fourth during 1966-75, and rise from 3.1 million in
1966 to approximately 3.9 million in 1975. This




projected increase in requirements will result from the
continued expansion of general economic activity and,
in particular, the continued rapid expansion of those
industries employing large numbers of clerical personnel,
such as finance, insurance, and real estate. Furthermore,
as modern business organizations continue to grow in
size and complexity, the volume of paperwork also will
expand.
Technological developments are not expected to
significantly limit growth in employment requirements
for stenographers, secretaries, and typists as a group
during the decade ahead. However, the increased use of
duplicating machines, flexowriters, dictating machines,
and other office equipment is expected to increase
output per employee, particularly of workers who
perform the more routine tasks.
In addition to manpower needs for occupational
growth, many secretaries, stenographers, and typists will
be needed to replace workers who transfer to other
occupations, or who withdraw from the labor force
because of death, retirement, family, or other reasons.
Each year, withdrawals from the labor force alone are
estimated to be between 4.5 and 5.5 percent of all
secretaries, stenographers, and typists.

SALES WORKERS

Current Employment
Approximately 4.8 million sales workers were em­
ployed in the United States in 1966. Most were
employed in retail trade. About one-fourth worked
part time or less than a 35-hour week. Women accounted
for about two-fifths of all persons in the occupation
group.
Training
The methods of acquiring training for sales work—
like
the work itself— Salesclerks who do little more than
vary.
wait on people to sell standardized merchandise seldom
have specialized training. They usually learn their duties
on the job by working with experienced salesclerks. In
some large stores, new workers may attend brief training
courses.
Sales workers who sell complex products or services,
such as computers or industrial machinery, sometimes
receive from their employers specialized training that
may last several months. Salesmen who must discuss
technical aspects of a product often receive the required
background through college programs in engineering or
some other related field. Those dealing in specialized
services and products may acquire the necessary tech­
nical knowledge by taking courses offered by colleges
and universities or by manufacturers. Still others gain
“know-how” through years of on-the-job experience,
often supplemented by home study.
Employment Trends and Outlook
Rising from about 3.4 million to about 4.8 million,
employment of sales workers increased about two-fifths
between 1947 and 1966. Increased sales of many new
products, resulting from rapid population growth, new
product development, business expansion, and rising
income levels, was the major reason for increased
employment of salesworkers.
Retail Sal

Current Employment
The largest group of salesworkers, about 2.6 million,
were employed in retail trade in 1966. Of this number,
nearly three-fifths were women who predominated in
20




Employment in some types of saleswork increased
faster than in others. Among the large sales occupations
that had particularly rapid growth are real estate
salesman, insurance agent, manufacturers’ salesman, and
wholesale salesman. Some smaller sales occupations such
as demonstrator, stock and bond salesman, and houseto-house salesman also increased rapidly. The number of
retail salesworkers grew very little; this occupation,
however, represents the largest category of sales workers.
Employment requirements for sales workers are
expected to reach 5.9 million in 1975, nearly one-fourth
above the 1966 level. The same factors that affected
employment growth in the past are expected to continue
to result in a growth of salesworker employment in the
future. In addition, employment prospects in a variety
of sales occupations will be enhanced by growth in
particular types of business activity. For example, the
expected increase in residential and commercial con­
struction and urban renewal will increase the need for
real estate agents; continued extension of laws such as
workman’s compensation and automobile liability insur­
ance should boost the need for insurance salesmen; and
continuation of the trend for stores in metropolitan
areas to remain open longer should increase the need for
retail salespersons. However, in recent years, the growth
of retail salesworker employment in many trade estab­
lishments, such as variety stores, supermarkets, and
department stores, has been limited by the increasing use
of self-service and checkout counters. This trend is
expected to continue, but at a slower rate than in recent
years. In addition, an increasing variety of goods are
expected to be merchandised through vending machines.
In addition to manpower needs for occupational
growth, many sales workers will be needed to replace
workers who transfer to other occupations, or who
withdraw from the labor force because of death,
retirement, family, or other reasons from 1966-75. For
example, each year, withdrawals from the labor force
alone are estimated at between 2.5 and 3.0 percent of all
sales workers.

in stores selling furniture, household appliances, hard­

The largest employers of retail salesworkers were
general merchandise (including department and variety
stores), food, and apparel stores; and motor vehicle and
accessory dealers. Substantial numbers of salesworkers
also were employed by lumber and building materials
dealers, drug, shoe, appliance, furniture and home
furnishings, and hardware and farm equipment stores.
Training
Salesworkers employed by retail establishments are
trained in a variety of ways. Newly hired sales personnel
usually receive on-the-job instruction in sales and store
methods. They learn about credit and other store
policies and any special information that is required to
sell a product. In a great many small stores, new
employees receive their training on the job, and work
under the close supervision of an experienced employee
or the proprietor. In large stores, training programs are
likely to be more formal, and beginners usually attend
training sessions for a few days.
Some salesworkers receive specialized sales training in
high schools that have distributive education programs.
Such programs include courses in merchandising, prin­
ciples of retailing, and retail selling. These schools also
provide an opportunity for students to gain practical
experience under trained supervision by working part
time in local stores. The Federal Government sponsors
training of retail salesworkers under the Manpower De­
velopment and Training Act of 1962. In 1966, about
2,400 persons were enrolled in MDTA institutional pro­
grams for retail salesworkers.
Wholesale

Employment Trends and Outlook
Rising from about 2.4 million to nearly 2.9 million,
employment of retail salesworkers increased about onefifth between 1950 and 1966. The major reason for this
increase in employment was increased sales of many
products, resulting from population growth, new prod­
uct development, business expansion, and rising income
levels.
Employment requirements for retail salesworkers are
expected to reach 3.2 million in 1975, about one-fourth
above the 1966 level. The projected increase in employ­
ment is based on anticipated increases in population and
disposable personal income, which will result in a rising
volume of sales. Also, the trend for stores in metro­
politan and suburban areas to stay open longer will re­
sult in the need for additional salesworkers. However,
the growth of retail salesworkers will be restricted as
variety and department stores and large supermarkets
continue to replace salesworkers with self-service and
check-out counters. In addition, vending machines are
expected to provide an increasing variety of goods once
handled by salesworkers.
In addition to manpower needs for occupational
growth, many retail salesworkers will be needed to re­
place those who transfer to other occupations, or who
die, retire, or withdraw from the labor force for family
or other reasons during 1966-75. For example, each
year, withdrawals from the labor force alone are esti­
mated to number between 3.0 to 3.5 percent of all retail
salesworkers.

Wholesale salesmen usually begin work in a trainee
job. Although the time spent in these initial jobs varies
among companies, 2 years or longer are required to pre­
pare for outside selling. Prospective salesmen often begin
in the stockroom, where they become familiar with the
items the wholesaler carries. They may transfer later to
the. pricing desk where they learn prices of articles and
discount rates for goods sold in quantities. Next, they
are likely to be “inside salesmen,” and write orders that
come from customers by telephone. After trainees have
become familiar with the company’s products, cus­
tomers, and techniques of selling, they are assigned a
territory of their own.
Employment Trends and Outlook
Employment of wholesale salesmen increased by
nearly two-fifths between 1950 and 1966, from about
510,000 to more than 700,000. New product develop­
ment, business expansion, and rising income levels were
major factors underlying the increased employment of
wholesale salesmen.
Employment requirements for wholesale salesmen are
expected to reach nearly 900,000 in 1975, about one-

fourth higher than the 1966 level. The expected growth
is based on a continued rising demand for goods and
services, and a corresponding increase in the amount of
business transacted by wholesale houses. In the next
decade, wholesale salesmen will spend an increasing pro­
portion of their time rendering special services to cus­
tomers; this practice, in turn, will add to the need for
sales personnel. As chain stores and other large business
firms continue to centralize their purchasing activities,
the value of the sales that wholesalers make to individual
customers will become larger and competition for sales
will be correspondingly greater. To meet this competi­
tion, wholesalers can be expected to place an increasing
amount of emphasis on sales activities.
In addition to manpower needs for occupational
growth, many wholesale salesmen will be needed to re­
place workers who transfer to other occupations, or who
withdraw from the labor force because of death, retire­
ment, or other reasons from 1966-75. For example, each
year, withdrawals from the labor force alone are esti­
mated to be between 2.0 and 2.5 percent of all whole­
sale salesmen.

Manufacturers, Salesmen 20

About 600,000 manufacturers’ salesmen were
employed in the United States in 1966. About threefourths of all manufacturers’ salesmen worked in non­
durable goods manufacturing industries. The printing
and publishing industry, the largest single employer of
sales workers (reflecting the large number of newsboys
employed), accounted for nearly two-fifths of all manu­
facturers’ salesmen. The food and kindred products
industry employed nearly one-fifth of these workers.
Other durable and nondurable goods industries which
have large numbers of manufacturers’ salesmen were
chemicals and allied products; fabricated metal products;
electrical and other machinery; and apparel.
Training
Large numbers of manufacturers’ salesmen are college
graduates. Many of those who sell technical products
and equipment, such as electrical equipment, heavy
machinery, and some types of chemicals, have college
training in engineering, chemistry, or other technical
specialties. Many salesmen of nontechnical products are
college graduates who have a degree in liberal arts or
business administration. Also, many persons who have
22




little or no training beyond high school are employed as
manufacturers’ salesmen; such workers generally sell
nontechnical products.
Beginning salesmen usually are given some company
sponsored training before they start on the job. Formal
training programs can last 2 years or more, especially in
companies manufacturing complex, technical products.
In some of these programs, trainees are rotated among
jobs in several departments of the plant and office to
learn all phases of production, sales, and distribution of
the products. Some training programs include formal
instruction in classes at the plant, sometimes followed
by intensive on-the-job training in a branch office under
the supervision of field sales managers.
Employment Trends and Outlook
Rising more than two-fifths from approximately
445,000 to about 600,000, the occupation of manu­
facturers’ salesmen grew rapidly between 1950 and
2 0 (D.O.T. 260. through 289.068, .118, .128, .151, .158,

because of further increases in population, income levels,
and industrial production. Furthermore, continued
development of new products and improvements in
marketing techniques are expected to heighten competi­

tion among manufacturers, and cause them to place
greater emphasis on their sales activities.
In addition to manufacturers’ salesmen who will be
required for occupational growth, many will be needed
to replace workers who transfer to other occupations, or
who withdraw from the labor force because of death,
retirements, or other reasons from 1966-75. For
example, each year, withdrawals from the labor force
alone are estimated to be between 2.0 and 2.5 percent of
all manufacturers’ salesmen.

Insuranee Agents and Brokers21

Current Employment
About 400,000 insurance agents and brokers were
employed in the United States in 1966, about 90
percent of whom were men. About half of all insurance
agents and brokers specialized in life insurance; the other
half sold property and casualty insurance.
Training
Most insurance agents and brokers entering the field
in recent years have had some college training. Many
have taken courses in accounting, economics, finance,
and business law as well as courses in insurance subjects.
Others have completed a liberal arts curriculum.
Before they start selling, new agents usually receive
training at insurance company home offices, or at the
agency or brokerage firms where they will be working.
Some insurance companies sponsor classes in sales
problems and insurance principles. This instruction may
be given over several weeks or a few months. In other
cases, training takes the form of working on the job
under the direct supervision of experienced sales
personnel.
Many agents and brokers have broadened their knowl­
edge of the insurance business by enrolling in inter­
mediate or advanced courses available at many colleges
and universities, and by attending institutes, confer­
ences, and seminars sponsored by insurance organiza­
tions. An insurance agent and broker can become
designated as a Chartered life Underwriter (CLU) or a
Chartered Property Casualty Underwriter (CPCU) by
passing a series of examinations.
All insurance agents and most brokers must obtain
licenses in the States where they plan to sell insurance.
In most States, licenses are issued only to applicants who
pass written examinations covering insurance funda­
mentals and the State insurance laws.




Employment Trends and Outlook
Employment of insurance agents and brokers
increased nearly one-half between 1950 and 1966, from
almost 275,000 to about 400,000. Factors contributing
to employment growth during this period were a
growing population; rising personal income; and longer
life expectancy, which resulted in greater interest in life
insurance to build adequate retirement funds. Also,
expansion in industrial plant and equipment and
increases in major consumer purchases such as homes
and automobiles added to the need for property and
liability agents and brokers.
Employment requirements for insurance agents and
brokers are expected to reach about 450,000 in 1975,
one-eighth higher than the 1966 level. This expected
increase in employment will result mainly from a rapidly
increasing volume of insurance business. As the popula­
tion continues to grow more individuals will purchase
life insurance as well as insurance to provide retirement
income and funds for children’s education. In the busi­
ness world, more property and liability insurance will be
required as new plants are built, new equipment is
installed, and more goods are shipped. Furthermore, as
the coverage of State workmen’s compensation laws is
broadened, more employers may need workmen’s com­
pensation insurance.
In addition to insurance agents and brokers who will
be required for occupational growth, many will be
needed to replace workers who transfer to other occupa­
tions, or who withdraw from the labor force because of
death, retirement, or other reasons from 1966-75. For
example, each year, withdrawals from the labor force
alone are estimated to number between 2.0 and 2.5
percent of all insurance agents and brokers.

CRAFTSM EN, FOREMEN, AND K IN D R ED WORKERS (SKILLED WORKERS)

Current Employment
More than 9.6 million craftsmen, foremen, and
kindred workers were employed in 1966. More than half
of these workers were employed in two broad occupa­
tional groupings—
construction craftsmen (29 percent)
and mechanics and repairmen (25 percent). Approxi­
mately 850,000 were carpenters and about 785,000
were automotive mechanics. Other skilled occupations
that had over 100,000 workers included painter; electri­
cian; plumber and pipefitter; skilled machining worker;
stationary engineer; excavating, grading, and road
machinery operator; bricklayer; appliance serviceman;
compositor and typesetter; tool and diemaker; and tele­
vision and radio service technician. However, many
skilled occupations, such as paperhanger, engraver, and
electrotyper, had fewer than 20,000 workers each.
Although skilled workers were employed in almost
every industry in 1966, more than three-fifths were
employed in manufacturing and construction. Those
manufacturing industries employing the largest numbers
of skilled workers included the primary metals, fabri­
cated metals, electrical machinery, machinery (except
electrical), transportation equipment, food and kindred
products, and printing and publishing. More than 90
percent of all craftsmen, foremen, and kindred workers
worked for private employers or Federal, State, or local
governments; the rest were self-employed. The occupa­
tions which have the largest number of self-employed
workers included carpenter, automobile mechanic,
painter, plumber and pipefitter, radio and television
service technician, and brickmason.
Training
Most craftsmen, foremen, and kindred workers
complete extensive training to qualify for their jobs.
Many skilled workers acquire the skills of their occupa­
tions through a formal apprenticeship program
consisting of systematic on-the-job training, supple­
mented by formal classroom instruction. Apprenticeship
programs generally last 4 years; however, they range
from 3 to 6 years. Some skilled workers also learn the
skills of their trade through formal training programs,
other than apprenticeship, offered by employers. These
programs generally provide systematic on-the-job
training and may include supplementary classroom
instruction.
24




Many workers acquire the knowledge to become
skilled workers by moving from one semiskilled job to
another over a period of years. In these cases, new
workers begin on the simplest task under the direction
of a foreman or an experienced worker and gradually
progress to more difficult work. Others learn a skilled
trade in vocational, trade, and technical schools. Some
workers in semiskilled or unskilled jobs qualify for more
skilled work by completing correspondence courses,
manufacturers’ training programs, or by taking voca­
tional courses in the evening. In addition, workers being
trained or retrained for skilled occupations make up one
of the largest groups to receive training in programs
operated under the Manpower Development and
Training Act of 1962.
The Armed Forces are an important source of skilled
workers. Training acquired in the Armed Forces often
qualifies persons for skilled jobs in civilian life, such as
automobile mechanic, electrician, or office machine
repairman.
Employment Trends and Outlook
Rising from almost 7.8 million to nearly 9.6 million,
employment of craftsmen, foremen, and kindred
workers increased nearly one-fourth between 1947 and
1966. Employment increased relatively rapidly in the
early years from 1947-66, and reached 8.4 million in
1951; but during 1951-62 employment changed rela­
tively little, and fluctuated between 8.3 million and 8.7
million. In 1963, however, employment increased
sharply to 8.9 million and by 1966, it stood at nearly
9.6 million.
Employment trends between 1950 and 1966 varied
sharply among the individual skilled occupations. For
example, although construction activity increased during
this period, employment of carpenters declined,
primarily as a result of growing use of prefabricated
building components and increasing efficiency of tools
and equipment. Employment of bakers also fell slightly,
chiefly as a result of increasing mechanization of bakery
production processes and fewer establishments in the
baking industry.
Many skilled occupations, on the other hand,
increased in numbers between 1950 and 1966. For
instance, increases in construction activity resulted in
significant employment gains for cement and concrete
finishers and terrazzo workers (67 percent); excavating,

grading and road machinery operators (137 percent);
plumbers and pipefitters (17 percent); and electricians
(23 percent). Significant employment gains also were
recorded for tool and diemakers (30 percent), primarily
because of a substantial expansion in metalworking
activity resulting from increased demand for metalconsumer products such as automobiles, heating and airconditioning equipment, and household appliances.
Employment of mechanics and repairmen grew more
rapidly than the skilled work force as a whole between
1950 and 1966. This dispariety resulted from the need
to maintain, repair, and install the growing volume of
increasingly complex equipment used in factories, stores,
offices, and homes. For example, employment of busi­
ness machine servicemen more than doubled, and
employment of television and radio service technicians
and appliance servicemen each increased more than onehalf.
Employment requirements for craftsmen, foremen,
and kindred workers are expected to reach about 11.4
million in 1975, 18 percent above the 1966 level.
Industrial growth and increasing business activity are the
major factors expected to increase the need for skilled
workers.
As in the past, rates of employment growth will differ
among the skilled occupations. Employment of
mechanics and repairmen is expected to continue to
grow more rapidly than the skilled work force as a
whole. Industry will need increasing numbers of crafts­
men to repair and maintain the automatic conveyor
systems, sensing and measuring devices, and other instru­
ments and equipment that are becoming an integral part
of modern industrial production processes. A growing
Airplane I

Current Employment
Approximately 120,000 airplane mechanics were
employed in the United States in 1966. Nearly 2 of
every 5 were employed by certificated scheduled and
nonscheduled airlines. About one-fourth worked for the
military and other agencies of the Federal Government.
The remaining mechanics were employed in general avia­
tion, primarily by certificated repair stations.
Training
Most airplane mechanics learn the skills of the trade
by working as trainees or apprentices. Large airlines give




stock of household appliances also should increase the
need for mechanics and repairmen.
Employment requirements for skilled workers in the
building trades and in the major skilled machining occu­
pations are expected to increase at slower rates than
mechanics and repairmen, since technological develop­
ments are expected to partially offset the rising demand
for construction and machining work. For example, as
more building components such as wall panels, door
frames, roof trusses, and precast concrete components
are prepared offsite, requirements will be reduced for
carpenters, cement masons, and structural metal
workers. Similarly, the growing use of plastic materials,
such as plastic pipes, polyfoam insulation, and plastic
shells may reduce requirements for skilled workers such
as plumbers, pipefitters, and brickmasons. Although
employment requirements in the machinery occupations
are expected to rise from 1966-75, the expanding use of
numerically controlled machines is expected to restrict
employment growth in these occupations. On the other
hand, employment in the printing trades, one of the
largest groups of skilled workers, is expected to show
little or no change over the next decade because of
laborsaving technological changes in printing methods.
In addition to manpower needs for the expected
growth in employment requirements, many skilled
workers will be needed to replace workers who transfer
to other fields of work, or who die, retire, or withdraw
from the labor force for other reasons during 1966-75.
For example, each year, withdrawals from the labor
force alone are estimated to number about 2.0 percent
of all craftsmen, foremen, and kindred workers.

apprentices or trainees 3 or 4 years of combined instruc­
tion and work experience. Persons who have learned air­
craft maintenance in the Armed Forces usually are given
credit for this training towards the requirements of
apprenticeship or other on-the-job training programs.
Other mechanics prepare for their trade by graduating
from a Federal Aviation Agency approved mechanics’
school. Most of these schools have an 18- to 24-month
program. Several colleges and universities also offer 2year programs that prepare students for the FAA
mechanic examination.

Airplane mechanics responsible for any repair or
maintenance operation must be licensed by the FAA. At
least 18 months’ experience working with airframes or
engines is required for an airframe or powerplant license,
and at least 30 months experience working with both
airframes and engines is required for a combined air­
frame and powerplant license. (However, this experience
is not required of graduates of FAA approved
mechanics’ schools.) In addition to meeting these experi­
ence requirements, applicants must pass a written test
and give a practical demonstration of their ability to do
the work. Mechanics who perform only specific main­
tenance and repair operations for which their employers
received FAA authorization must have still another type
of FAA repairman license.
Mechanics who maintain and repair electronic
communications equipment are required to have at least
a Federal Communications Commission Second Class
Radio Telephone Operator License.
Employment Trends and Outlook
Employment of airplane mechanics more than
doubled between 1950 and 1966, increasing from
approximately 50,000 to an estimated 120,000.
Employment of airplane mechanics working for the
scheduled airlines, who make up the largest single group
in this occupation, increased slightly faster than those
employed by nonscheduled airlines, general aviation
firms, and government, combined. The rapid growth in
employment of airplane mechanics during the 1950’s
and early 1960’s was chiefly the result of .dramatic
increases in civil flying activity and in the number of
registered aircraft; between 1954 and 1966, the total
number of eligible registered aircraft on record with the
FAA increased from slightly more than 60,000 to almost
95,000, a rise of about two-thirds. In addition, super­

sonic military aircraft required more intensively trained
mechanics.
Employment requirements for airplane mechanics are
expected to reach about 140,000 by 1975, an increase
of more than 15 percent over 1966. This projected
increase will result primarily from the anticipated
growth in civil flying activities, including a rapid rise in
the number of operating aircraft. However, employment
requirements for airplane mechanics are not expected to
increase as fast as civil flying activities, due to techno­
logical improvements that will increase the efficiency of
aircraft maintenance work and reduce the ratio of
mechanics to operating aircraft.
A large percentage of the projected growth in civilian
aircraft is expected to occur in general aviation aircraft,
especially among business aircraft users and small
commercial operators. The major stimulus for this
increase, and the consequent need for mechanics to
maintain general aviation aircraft, will result from the
rising demand for fast, dependable, and flexible air trans­
portation services.
The number of airplane mechanics required by the
scheduled airlines is expected to continue increasing
from 1966-75 because of a substantial rise in operating
aircraft engaged in passenger and cargo traffic. An
increase in requirements also is expected because of the
need to service the growing array of complex naviga­
tional and control systems being incorporated into
modern jet transports.
In addition to manpower needs for occupational
growth, many mechanics will be required to replace
workers who transfer to other occupations, or who with­
draw from the labor force because of death, retirement,
or other reasons during 1966-75. For example, each year
withdrawals from the labor force alone are estimated to
number between 1.0 and 1.5 percent of all airplane
mechanics.

Automotive Mechanics23

Current Employment
About 785,000 automotive mechanics were
employed in the United States in 1966. Included in the
occupation classification are automobile mechanics,
truck mechanics, bus mechanics, and body repairmen.
About three-fourths of these workers are automobile
mechanics.
Approximately two-fifths of all automotive
mechanics are employed in independent automotive
26




repair shops. About one-fourth are employed in the
service departments of new and used car and truck
dealers. More than 1 of every 10 mechanics are
employed by organizations that maintain and repair
their own motor vehicles, such as trucking companies,
automotive leasing companies, and government agencies.
Gasoline service stations and department stores employ

807.381, and 825.281), D i c t i o n a r y o f O c c u p a t io n a l T it le s , U.S.
Department of Labor 1966, 3d edition.

most of the rest to provide automotive repair services.
The majority of automotive mechanics work in shops
employing from 1 to 5 mechanics. Some of the largest
repair shops, however, employ more than a hundred
automotive mechanics.
Training
Automotive mechanics acquire their training in a
variety of ways. Most automotive mechanics learn the
trade on the job. They usually start out as helpers, lubri­
cation men, or gasoline station attendants, and gradually
acquire knowledge and skills by working with experi­
enced mechanics or supervisors. Although beginners
usually are able to do simple repairs after a few months’
experience, at least 3 to 4 years of on-the-job training
and experience are required generally to become an all­
round mechanic. In contrast, mechanics who specialize
exclusively in the repair of items such as radiators,
brakes, or front-ends generally learn their specialty in
about 2 years of on-the-job training.
Many automotive mechanics obtain formal training
either in high school; in trade or technical school; in the
Armed Forces; through correspondence school courses;
through apprenticeship programs; or through combina­
tions of these types of training. A relatively small
number of graduates of automotive mechanic programs
in vocational high schools are selected each year to
attend factory sponsored training programs for
beginners. At the beginning of 1967, about 5,200
persons were enrolled in registered apprenticeship
programs for “automobile mechanic,” a classification
that includes truck and bus mechanics. A small number
of additional workers were in unregistered apprentice­
ship programs. Also, automotive mechanics make up one
of the largest groups of workers to receive training under
the Manpower Development and Training Act of 1962;
in 1966, about 7,200 persons were enrolled in MDTA
institutional programs for automotive mechanics.
Many dealers send experienced mechanics to factory
training centers, for brief periods, to learn how to repair
new car models, or to repair special parts such as auto­
matic transmissions or air-conditioners. Manufacturers




also send representatives to local shops to conduct short
training sessions for the shops’ mechanics.
Employment Trends and Outlook
Automotive mechanic employment increased from
about 650,000 to 785,000 between 1950 and 1966, a
rise of about 20 percent. The number of motor vehicles
in use— principal determinant of mechanic employ­
the
ment-increased almost 88 percent during the same
period, rising from about 49 million to more than 92
million. The disparity between the rates of growth in
employment and in the number of motor vehicles was
largely the result of a decline in automotive mechanic
requirements for vehicle maintenance. During 1950-66,
the average age of motor vehicles in use dropped sharply
and, reflected the availability of new vehicles following
World War II and high scrappage rates for those
produced before the war.
Employment requirements for automotive mechanics
are expected to reach about 940,000 in 1975, about
one-fifth above the 1966 employment level. The pro­
jected increase is based primarily on an anticipated
expansion of more than one-fourth in the number of
motor vehicles in use between 1966 and 1975. The need
for mechanics also will increase because an increasing
proportion of vehicles are expected to have airconditioning, power steering, devices to reduce exhaust
fumes, and other features that add to repair and main­
tenance needs. The effects of the increasing number of
vehicles and their greater complexity will be offset
partially by decreasing mechanic labor requirements for
each vehicle resulting from factors such as growing
mechanic and repair shop specialization; greater
emphasis on replacement rather than repair of parts; and
increasing use of laborsaving equipment, including dynamoneters, engine analyzers, and power tools.
In addition to manpower requirements for occupa­
tional growth, many mechanics will be needed to replace
workers who transfer to other occupations, or who with­
draw from the labor force because of death, retirement,
or other reasons during 1966-75. For example, each
year, withdrawals from the labor force alone are esti­
mated to number between 1.0 and 1.5 percent of all
automotive mechanics.

27

Bakers24

Current Employment
More than 100,000 bakers were employed in 1966.
This occupation classification includes a wide variety of
specialized occupations such as all-round bakers, batter
mixers, bench hands, dough mixers, and ovenmen.
About 7 of every 10 bakers were employed in the
bakery industry in 1966. Nearly one-fourth were
employed in retail bakeries that produced their own
baked goods, and the rest worked in establishments such
as schools, hospitals, hotels, and restaurants.
Training
Bakers usually acquire their training by working as
helpers to skilled bakers. Helpers wash and grease pans,
carry ingredients to mixing machines, push troughs of
dough to the proofing room, and otherwise assist skilled
bakers.
Some bakers learn the skills of the trade through
formal apprenticeship programs. Apprenticeship
programs last 3 or 4 years, and include on-the-job
training in all baking operations and related classroom
instructions.
Other workers acquire baking skills by taking courses
in vocational schools or by learning some aspects of the
trade in the Armed Forces. Although such training may
not qualify a worker as a skilled baker, it may help him
to become an apprentice and perhaps shorten his appren­
ticeship period. Some bakers receive training in programs
operated under the Manpower Development and
Training Act of 1962.
Employment Trends and Outlook
Total employment of bakers decreased from about
120,000 to about 100,000 between 1950 and 1966.

Factors that contributed to the employment decrease
included increasing mechanization of bakery production
processes and fewer establishments in the baking
industry. For example, between 1960 and 1966, the
total number of industrial bakeries declined approxi­
mately 15 percent.
Employment requirements for skilled bakers are
expected to decrease slightly to more than 95,000 from
1966-75. Increasing efficiency in production methods of
industrial bakeries is expected to more than offset the
growing demand for bakery products. The automation
of dough mixing through the continuous mix process
virtually eliminates manual operations and increases pro­
duction capacity. In addition, the increasing use of
mechanical devices that require a minimum of direct
labor to produce such specialty products as French
bread and club rolls will reduce employment require­
ments.
The growing use of freezing processes also is expected
to reduce employment requirements for bakers. Freezing
processes make possible the storage of dough and baked
goods for future use; eliminate the need for bakers for
second and third shifts; increase the distribution area for
an establishment’s bakery products; and contribute to
decreases in the number of establishments necessary to
serve an area.
Despite declining manpower needs for skilled bakers
during 1966-75, many thousands of bakers will be
needed to replace those who transfer to other fields of
work, or who die, retire, or otherwise withdraw from the
labor force. For example, each year, withdrawals from
the labor force alone are estimated to number between
2.0 and 2.5 percent of all bakers.

Business Machine Servicemen25

Current Employment
Approximately 80,000 business machine servicemen
were employed in the United States in 1966. Included in
the occupational classification are typewriter service­
men, adding machine servicemen, calculating machine
servicemen, accounting-bookkeeping machine service­
men, data-processing equipment servicemen, dictating
machine servicemen, duplicating and copying machine
28




servicemen, and servicemen of postage and mailing
equipment.
About one-third of all business machine servicemen
employed in 1966 were servicing and repairing type­
writers, and approximately one-fifth serviced dataprocessing equipment. Other sizable proportions were

Department of Labor, 1966, 3d edition.

employed to service and repair adding machines, calcu­
lators, cash registers, and duplicating and copying
machines.
It is estimated that in 1966 the majority of business
machines servicemen were employed in establishments
that manufacture business machines. A large number
were employed by independent retailers in repair shops
that service business machines. The remaining service­
men worked in a variety of industries, in establishments
that had enough machines in daily use to justify
employing full-time servicemen.
Training
Many business machine servicemen acquire their skills
through a combination of on-the-job training, work
experience, and instruction in manufacturers’ training
schools. Men hired as trainees in manufacturers’ branch
offices usually are sent to company schools for periods
lasting from several weeks to several months; the time
required depends upon the type of machines they will
service. They then receive from 1 to 3 years of practical
experience and on-the-job training. During this period,
they may occasionally go back to factory schools for
additional training.
Some business machine servicemen learn the trade by
working with experienced servicemen in independent
shops. Men in independent shops usually receive little
formal training. The time required to become a skilled
servicemen tends to be somewhat longer in independent
shops than in manufacturers’ branches, because of the
greater variety of machines and the generally informal
nature of the training.
The length of the training period of both manu­
facturers’ branch offices and independent shops varies in
relation to the complexity of the equipment. To service
calculating machines, about 2 years of training and
experience are required. Cash register repairmen learn
their job in 2Vi to 3Vi years, the last 6 months of which
usually are spent in a company school. Skilled
accounting-bookkeeping machine repairmen generally
must have at least 3 to 4 years of training and
experience. During the first 1 to 2 years they service
adding machines, calculators, or cash registers, since such
experience is considered valuable background for
servicing accounting-bookkeeping machines.
Courses in business machine maintenance and repair
conducted by some State and city vocational schools
and by private correspondence schools also are a means
of learning the skills of the trade. Few business machine
servicemen, however, learn in this manner. Some service­
men received training in programs operated under pro­




visions of the Manpower Development and Training Act
of 1962.
Employment Trends and Outlook
Estimated employment of business machine service­
men more than doubled during the post-World War II
period and reached about 80,000 in 1966 due to
increasing use of many types of office machines to do
clerical work. Additional business machine servicemen
were employed to maintain and service increasing
numbers of office machines used for correspondence,
recording and processing transactions, and duplicating
and mailing information. In addition to greater numbers
of machines, many technical changes in long-established
types of business machines increased the need for
servicemen. For example, electrically driven mechanical
equipment, including electric typewriters and adding
machines, rapidly is replacing nonelectrical mechanical
machines. In recent years, the number of duplicating and
copying machine servicemen and dictating machine
servicemen has grown fastest, and calculating machine
servicemen, slowest.
Employment requirements for business machine
servicemen are expected to reach about 105,000 by
1975, an increase of about 30 percent over the 1966
level. This projected increase in employment require­
ments is based on the expected increase in the use of
business machines, resulting in part from continued tech­
nological improvements in office equipment. The
development of new types of business machines and
improvements in present equipment are expected not
only to increase the demand for skilled servicemen but
also to affect changing skill requirements in existing
jobs. Those occupations expected to grow fastest are
typewriter serviceman, data-processing equipment
serviceman, and duplicating and copying machine
serviceman. Those occupations in which employment is
expected to grow less rapidly are calculator serviceman,
cash register serviceman, and serviceman of postage and
mailing equipment.
In addition to manpower requirements for occupa­
tional growth, many servicemen will be needed to
replace workers who transfer to other occupations, or
who withdraw from the labor force because of death,
retirement, or other reasons during 1966-75. However,
because many of the workers in this occupation are rela­
tively young, estimated annual withdrawals from the
labor force will number less than 1.0 percent of all
business machine servicemen.

About 170,000 compositors and typesetters were
employed in the United States in 1966. They represent­
ed the largest printing craft occupation—
nearly half of
all printing trades craftsmen. Nearly 9 out of 10 of these
workers are males. More than four-fifths of all composi­
tors and typesetters worked in the printing, publishing,
and allied industries in 1966. Others were employed in
the paper and allied products industry ; in wholesale and
retail trade; in finance, insurance, and real estate; and in
government.

Employment of compositors and typesetters was
about the same in 1966 as in 1950, despite an approxi­
mate two-thirds increase in the production of printed
materials. Employment growth was limited by increasing
technological innovations in typesetting equipment and
by changes in printing processes that make it possible to

Excavating, Grading, and Road Machinery Operators30
Current E m ploym en t

Nearly 270,000 excavating, grading, and road
machinery operators were employed in the United States
in 1966. About three-fourths of these workers were
employed in the construction industry primarily by con­
tractors engaged in highway, dam, airport, and other
large-scale engineering projects. Others were employed
by utility companies, manufacturers, and other business
firms that do their own construction, as well as by State
and local public works and highway departments.
Training

Most training authorities recommend completion of a
3-year apprenticeship program as the best way to acquire




the skills needed to be excavating, grading, or road
machinery operators. In 1966, only a small number of
individuals were enrolled in apprenticeship training
programs for these occupations.
Many excavating, grading, and road machinery opera­
tors acquire their training on the job. Such individuals
generally enter the occupation through jobs as oilers
(assistants) or as helpers to heavy equipment repairmen;
gain a knowledge of the machinery ; and learn to keep it
in good working order and to make repairs. Oilers and
helpers must perform their work well and demonstrate
initiative before they are given instruction in operating

increase in employment requirements is based primarily
on an anticipated rapid increase in construction activity
resulting from rising population, increasing family
formations, and growing personal and corporate income.
In addition, plumbing and heating work is expected to
become more important in many types of construction.
For example, the trend toward more bathrooms for each
dwelling unit is likely to continue. The installation of
large appliances such as washing machines, dishwashers,
and water-disposal units will become more widespread.
Also, an increase in the number of automatic heating
systems is anticipated.
The demand for installation workers also will rise
because pipework is becoming important in many
industries. For instance, the chemical and petroleum
industries, which use extensive pipework in their
processing activities, are continuing to expand their
facilities. In addition, more maintenance and repair work
for plumbers and pipefitters should result from the
growing number of industrial activities associated with
atomic energy, and the increased use of industrial
refrigeration and air conditioning.

Employment growth, however, will be limited some­
what because of laborsaving technological innovations. A
major development increasing the efficiency of plumbing
and pipefitting work is the prefabrication of pipefitting
components. For example, prefabricated plumbing
assemblies such as plumbing “trees” are available from
manufacturers. Such a system can be installed as one
unit, thereby reducing the amount of on-site plumbing.
Plastic plumbing, which is being used increasingly for a
wide variety of plumbing operations, increases the
number of installations for each plumber and pipefitter
because it is light in weight and easily handled by one
individual.
In addition to manpower requirements for occupa­
tional growth, many plumbers and pipefitters will be
needed each year to replace workers who transfer to
other fields of work, or who withdraw from the labor
force because of death, retirement, or other reasons. For
example, each year, withdrawals from the labor force
alone are estimated to number between 1.5 and 2.0
percent of all plumbers and pipefitters.

Stationary igineers 33
Current E m ploym en t

About 260,000 stationary engineers were employed
in the United States in 1966. Almost one-half were
employed in manufacturing industries, mainly in estab­
lishments producing electrical machinery, fabricated
metals, food and kindred products, petroleum and coal
products, and machinery (except electrical). Gas and
electric utility firms, mines, and Federal, State, and local
governments also employed large numbers of stationary
engineers.
Training

Stationary engineers acquire their skills either
through formal apprenticeship or informal on-the-job
training. An apprentice training program customarily
lasts 4 years and includes on-the-job training, related
classroom instruction, and home study. Through on-thejob training, the apprentice learns to operate, maintain,
and repair stationary equipment, and to use a variety of
hand and machine tools. Classroom work includes
instruction in technical subjects such as practical
chemistry; elementary physics; blueprint reading;
applied electricity; and the theory of refrigeration, air
conditioning, ventilation, and heating.
36




Persons who become stationary engineers without
going through a formal apprenticeship program generally
do so only after many years of experience as assistants
to licensed stationary engineers in such occupations as
boiler, refrigeration, or turbine operator. This practical
experience usually is supplemented by technical or other
school training, or home study.
Eight States and more than 50 large and medium-size
cities have licensing requirements for stationary
engineers. Stationary engineer licenses, which are issued
for several classes of work, specify the steam pressure or
horsepower of the equipment the engineer may operate.
Although requirements for obtaining a license differ
from place to place, the following are typical: (1) The
applicant must be over 21 years of age; (2) he must have
resided in the State or locality in which the examination
is given for a specified period of time; and (3) he must
demonstrate that he meets the experience requirements
for the class of license requested. A license is issued to
applicants who meet these requirements and pass an
examination, which may be written, oral, or a combina­
tion of both.

Television and Radio Service Technicians34

Current Employment
About 120,000 television and radio service techni­
cians were employed in the United States in 1966.
Three-fourths of these workers, including the one-third
who were self-employed, worked in independent service
shops or in retail stores that sell and service television
receivers, radios, and other electronic equipment. Most
of the rest were employed in a number of different
industries, such as electrical machinery manufacturing,
wholesale trade, and government; however, less than 10
percent of these service technicians were employed in
any one industry.
Training
Television and radio service technicians may acquire
their electronics training in a variety of ways, including
technical or vocational school programs, home study
(correspondence school) courses, or military service
training. In addition, on-the-job experience must be
obtained; this experience may consist of helping
qualified television and radio service technicians. From 2
to 3 years of combined electronics training and on-thejob experience generally are required to become a
qualified service technician.
A few persons without previous electronics training
may be hired as helpers or apprentices if they show
aptitude for the work, or, like the amateur (“ham”)
radio operator, have a hobby in electronics.
Some radio and television service technicians receive
training through programs operated under provisions of




the Manpower Development and Training Act of 1962.
In 1966, about 800 workers were enrolled in MDTA
institutional training programs for television and radio
service technicians. These programs generally last from
about 6 months to 1 year.
Several States and cities require television and radio
service technicians to be licensed. To obtain a license,
applicants must pass an examination to show their skill
in the use of testing equipment and their knowledge of
electronic circuits and components.
Employment Trends and Outlook
Employment of television and radio service techni­
cians increased from about 75,000 to approximately
120,000 between 1950 and 1966. This increase v/as
mainly the result of the tremendous growth in the
Nation’s stock of television, radios, and other consumer
electronic products. The growing use of home electronic
products resulted from rising levels of consumer income
and the introduction of new and improved products.
The number of households which have television sets,
for example, increased from less than a half million in
1947 to about 54 million in 1966.
Employment requirements for television and radio
service technicians are expected to reach about 140,000
in 1975, one-sixth above the 1966 level. The projected
increase in requirements for these workers is based on an

37

anticipated continued rapid increase in the number of
consumer electronic products during 1966-75. The
number of households which have two or more tele­
vision receivers is expected to increase significantly
because of the growing demand for color and light­
weight, portable television receivers. Demand also is
expected to continue to increase for other consumer
electronic products such as stereophonic radios and
phonographs, AM-FM radios, and portable transistor
radios. Relatively new consumer products, such as home
video-tape recorders, also should stimulate the need for
additional service technicians. In addition, there should
be a growing demand for nonentertainment electronic
products such as closed-circuit television to monitor
production processes in manufacturing plants and to
bring educational programs into classrooms. However,

employment requirements for television and radio
service technicians are not expected to increase as
rapidly as the stock of consumer electronics products
because technological improvements, such as replacing
tubes with transistors, using printed circuit boards
instead of handwired chassis, and substituting solid-state
amplifiers for amplifiers using vacuum tubes, will tend to
reduce the amount of service the equipment requires.
In addition to manpower requirements for occupa­
tional growth, many service technicians will be needed
to replace workers who transfer to other occupations, or
who die, retire, or otherwise withdraw from the labor
force during 1966-75. For example, each year, with­
drawals from the labor force alone are expected to
number between 1.0 and 1.5 percent of all television and
radio service technicians.

Bricklayers35

Current E m ploym en t

About 170,000 bricklayers were employed in the
United States in 1966. The great majority, nearly 90
percent, are employed in the construction industry. The
remaining bricklayers work for industries, such as those
producing glass or steel, where furnaces and kilns require
special fire brick and refractory brick linings. For
example, in a steel mill, the bricklayer uses refractory
bricks to line converters, cupolas, and ladles that hold
molten metal.
Training

Bricklayers acquire their training in a variety of
ways. Approximately half of the bricklayers learn the
trade through informal on-the-job training. Some start as
helpers or hod carriers, and gradually acquire knowledge
and skills by working with and observing experienced
bricklayers. Although beginners are able to do some of
the simpler phases of the work after a few months
experience, several years of on-the-job training and
experience generally are required to become a skilled
bricklayer.
Employment requirements for bricklayers are
expected to increase from 170,000 to approximately
200,000 between 1966 and 1975. Much of the expected
growth will result from the anticipated large increase in
construction activity. The factors that will stimulate
construction activity include anticipated increases in
population and in the number of households; a
38




continuing shift of families from cities to suburbs;
increasing government expenditures for schools; and a
growing demand for alteration and modernization work
on existing structures. The demand for bricklayers also
will be stimulated by such factors as the increasing use
of structural clay tile for fire-resistant partitions; glass
blocks for exterior walls; and ornamental brickwork for
structures, such as exterior screen walls and lobbies and
foyers. In addition, the use of brick and masonry
load-bearing walls is growing, particularly in apartment
buildings. On the other hand, growth in employment
requirements will be limited to some extent by the
construction techniques described previously, and by
recent developments that have increased the efficiency
of bricklaying such as high-strength mortars that can be
applied with caulking guns or compressor-powered
extruders.
In addition to manpower needs for occupational
growth, many bricklayers will be required to replace
workers who transfer to other fields of work, or who
withdraw from the labor force because of death,
retirement, or other reasons during 1966-75. For
example, each year, withdrawals from the labor force
alone are estimated to number between 1.5 and 2.0
percent of all bricklayers.
About half of the bricklayers obtain formal training,
including apprenticeship. In early 1967, nearly 9,500

Appliance Servicemen36

Approximately 195,000 appliance servicemen were
employed in the United States in 1966. Included in the
occupational classification are servicemen who repair
appliances ranging from toasters and food mixers, which
are relatively uncomplicated, to refrigerators and
washing machines, which may have complex control
systems.
More than half of all appliance servicemen in 1966
owned or were employed by independent repair shops
and firms that specialize in servicing coin-operated
washing and dry cleaning machines. About one-fourth
were employed by retail establishments, including
department stores. The rest were employed by appliance
manufacturers and wholesale distributors who operated
service centers, and by gas and electric utility companies.
Training
Most appliance servicemen acquire their skills through
on-the-job training and work experience. In addition to
practical experience on the job, trainees frequently
receive classroom instruction given by appliance manu­
facturers and local distributors. Many trainees take
correspondence school courses in basic electricity or
attend technical schools to increase their skills in
appliance repair. From 6 to 12 months are required for a
trainee to become a qualified gas appliance serviceman.
Electrical appliance servicemen usually need up to 3
years on-the-job experience to become fully qualified.
Many experienced servicemen attend training classes
(often on company time) and study service manuals to
become familiar with new appliances and the best ways
to repair them.
Employment Trends and Outlook
Rising from approximately 125,000 to about
195,000, employment of appliance servicemen increased




nearly three-fifths between 1950 and 1966. This increase
resulted from the introduction of many new types of
electric household appliances, such as knife sharpeners,
can openers, and portable hair dryers, and the more
extensive use of some household appliances, such as
freezers, dishwashers, and automatic coffee makers. The
estimated number of all household appliances in use
more than doubled between 1950 and 1966.
Employment requirements for appliance servicemen
are expected to increase to about 250,000 in 1975. The
projected increase in employment requirements is based
on an anticipated rapid increase in the number of
household appliances in use and result from rising
population, increasing family formations, and increasing
personal disposable income. The demand for appliances
also will be stimulated by the introduction of new
appliances, some of which may be cordless like many
automatic tooth brushes now in use, and by the
improved styling and design of appliances to make them
attractive and easy to operate. In addition, more
widespread use is expected of such appliances as waste
disposers, home clothes dryers, and coin-operated
drycleaning machines.
Employment of appliance servicemen is not expected
to increase as rapidly as the number of appliances that
will be in use. Although the automatic operation of
some types of appliances has tended to make them more
complicated, manufacturers are designing appliances
with more durable components and appliances that can
be taken apart and repaired more easily. In addition,
employers are increasing the efficiency of servicemen
through more widespread and more effective training.
In addition to manpower requirements for occupa­
tional growth, many servicemen will be needed to

replace workers who transfer to other occupations, or
who die, retire, or withdraw from the labor force for
other reasons during 1966-75. For example, each year,

withdrawals from the labor force alone are estimated to
number between 1.5 and 2.0 percent of all appliance
servicemen.

Tool- and Die-Makers37

Current Employment
Approximately 150,000 tool- and die-makers were
employed in 1966—
nearly all in manufacturing
industries. Establishments producing machinery (except
electrical) employed the largest proportion of these
workers (almost one-third). Large numbers also were
employed in establishments producing transportation
equipment, fabricated metal parts, electrical machinery,
and primary metals.
Training
These workers learn the trade in one of two wayseither through formal apprenticeship or equivalent onthe-job training. A tool and die apprenticeship ordinarily
lasts 4 to 5 years. Most of the time is devoted to
on-the-job shop training, but there also is some class­
room training in shop mathematics, shop theory, me­
chanical drawing, tool designing, and blueprint reading.
Many workers who qualify for the more difficult tool
and die work complete several years of experience after
their apprenticeship. Some workers complete separate
apprenticeship programs for both toolmaking and die­
making.
Many learn the trade on the job without completing a
formal apprenticeship. After acquiring years of
experience as machine tool operators or as machinists,
plus vocational or correspondence school training, these
men have developed into all-round craftsmen who can
skillfully perform almost any metal machining opera­
tion, including tool and die making.
Employment Trends and Outlook
Employment of tool- and die-makers increased nearly
one-third between 1950 and 1966, from 115,000 to
about 150,000. This increase was the result of a
substantial expansion in machining activity.
Employment requirements for tool- and die-makers
are expected to increase to about 165,000 in 1975. The

40




projected increase is based on anticipated expansion in
the machinery, electrical equipment, and other metal­
working industries. Population expansion and increasing
personal disposable income are expected to result in a
large increase in the demand for metal consumer
products such as automobiles, heating and airconditioning equipment, and household appliances.
Expanding business and consumer demand should result
in higher expenditures for new industrial plant capacity,
and stimulate orders for products manufactured in the
metalworking industries such as industrial machinery,
machine tools, materials handling equipment, engines,
and instruments. In addition, expanding construction
activity is expected to stimulate the demand for con­
struction machinery.
Growth in employment requirements for tool- and
die-makers is expected to be limited somewhat by the
increasing use of laborsaving technological innovations
such as numerically controlled machines. Numerically
controlled machining operations require fewer and less
complex special tools, jigs, and fixtures made by tooland die-makers. In addition, numerically controlled
machines can replace many of the conventional
machines now used in manufacturing tools, jigs, and
fixtures; thus, output for each tool- and die-maker will
be increased. However, tool- and die-makers employed in
metalworking repair shops and research and develop­
ment laboratories are less likely to be affected by the use
of numerically controlled machines than workers in
other types of establishments.
In addition to manpower needs for occupational
growth, many tool- and die-makers will be required to
replace workers who transfer to other occupations, or
withdraw from the labor force because of death,
retirement, or other reasons during 1966-75. For
example, it is estimated that, each year, withdrawals
from the labor force alone will number between 1.5 and
2.0 percent of all tool- and die-makers.

SEM ISKILLED WORKERS (O PERATIVES)

Current Employment
About 13.9 million workers were employed in semi­
skilled (operative) jobs in 1966. An estimated 6 of every
10 of these workers were employed in manufacturing.
About 40 percent of the operatives in manufacturing
were employed in the following occupational categories:
assemblers; checkers, examiners, and inspectors; drivers
and deliverymen; filers, grinders, and polishers; packers
and wrappers; sewers and stitchers; welders and flame
cutters; and production painters. Each of these occupa­
tional categories had more than 100,000 workers, and
four of them—
assemblers; checkers, examiners, and
inspectors; sewers and stitchers; and drivers and deliverymen— more than 500,000 workers each. Many
had
operative jobs are peculiar to particular industries; for
example, almost all sewers and stitchers were employed
in the apparel industry. On the other hand, some
occupations, such as truck and tractor drivers, were
distributed throughout all industries.
In 1966, about 4.1 million women were employed in
semiskilled jobs. The proportion of women employed in
different industries varies. Women accounted for 8 out
of 10 operatives in the apparel industry. Large numbers
of women also were employed in semiskilled occupa­
tions in the textile and food processing industries. On
the other hand, plants that produce iron and steel and
petroleum products employ relatively few women in
operative jobs.
Training
Semiskilled workers generally learn their jobs by
completing brief periods of training on the job. The
repetitive and routine tasks performed by these workers
can be learned quickly and mastered in a few weeks.
Even those jobs that require a higher degree of skill, such
as truckdriver, can be learned in a few months. In
general, new workers are told exactly what to do and
their work is supervised closely.
Employment Trends and Outlook
Rising from about 12.3 million to 13.9 million,
employment of semiskilled workers increased about 13
percent between 1947 and 1966. Employment fluc­




tuated between 11.8 million and 12.8 million in the
decade following World War II but, in 1958, the number
dropped to 11.4 million and remained between 11
million and 12 million for the next 3 years. Since 1961,
however, there have been significant increases in employ­
ment of semiskilled workers, primarily because of the
increase in manufacturing employment.
Employment trends among the individual semiskilled
occupations have varied since World War II, and have
reflected the different rates of growth of the industries
in which the workers were employed. However, employ­
ment trends also reflected the differing impact of
technological innovations on occupations. For example,
the rapid decline in employment of spinners and weavers
reflected not only the relatively small increase in the
demand for textile mill products, but also the increased
mechanization of spinning and weaving processes.
Employment requirements for semiskilled workers
are expected to reach about 14.8 million in 1975, 7
percent above the 1966 level, despite continued tech­
nological advances that will reduce employment require­
ments for some types of semiskilled occupations.
Increases in production generated by a rising population
and rapid economic growth, as well as an increasing
trend in motor truck transportation of freight, are
expected to be the main factors contributing to
increased employment requirements.
Employment trends among the various occupations
are expected to differ through the mid-1970’s. Tech­
nological innovations are expected to have the greatest
impact on employment requirements for semiskilled
workers in manufacturing. For example, the use of
numerically controlled machines for boring, drilling,
lathing, and milling of metal parts should limit the
increase of employment requirements for machine tool
operators. On the other hand, employment requirements
for truck drivers are expected to rise rapidly, as the
volume of freight carried in trucks continues to increase.
In addition to manpower requirements for occupa­
tional growth, many semiskilled workers will be needed
to replace those who transfer to other occupations, or
who withdraw from the labor force because of death,
retirement, or other reasons over 1966-75. It is
estimated that, each year, withdrawals from the labor
force alone number between 2.0 and 2.5 percent of all
semiskilled workers.

Machine Tool Operators38

Current Employment
About 500,000 machine tool operators were
employed in 1966-the largest machining occupation in
the metal working trades. Within this occupation classifi­
cation are lathe operators, milling machine operators,
boring machine operators, and drill press operators.
About 9 of every 10 machine tool operators were
employed in four industry groups—
machinery, except
electrical; transportation equipment; electrical
machinery; and fabricated metal products.
Training
Although some companies provide formal training to
acquaint new employees with the details of machine tool
operation and machinery practice, most machine tool
operators acquire their skills on the job. They begin by
observing a skilled operator, and learn how to use
measuring instruments and to make elementary compu­
tations needed in shop work. After these skills are
acquired, they operate the machine tool, read blueprints,
and plan the sequence of machinery work. To become a
semiskilled machine tool operator generally requires a
few months experience. Another IVi to 2 years of
on-the-job training and experience usually are required
to become a skilled machine operator.
Employment Trends and Outlook
Employment of machine tool operators increased
from about 450,000 to 500,000 between 1954 and

1966, or by about 11 percent. This increase in employ­
ment resulted primarily from the expansion of metal­
working activity in the machinery, fabricated metals,
and electrical equipment industries. Employment of
machine tool operators, however, rose much less rapidly
than output in these industries as a result of increased
use of automatic transfer equipment, and improvements
in the power, speed, and specialization of conventional
tools. Numerically controlled machine tools were intro­
duced during this period; further increases in output
resulted for each machine tool operator.
Employment requirements for machine tool
operators are expected to remain about the same
between 1966 and 1975 as laborsaving technological
innovations, such as the greater use of numerically
controlled machine tools and automatic transfer equip­
ment, about offset the anticipated expansion in metal­
working activities. The substantial rise in population, in
the number of households, and in disposable income is
expected to increase the demand for metal consumer
products such as automobiles, heating and airconditioning equipment, and household appliances. In
addition, expanding business requirements for industrial
plant capacity should stimulate the demand for
machinery, machine tools, engines, materials handling
equipment, instruments, and other machine products.
Also, expanding construction activity is expected to
increase the demand for construction machinery.
Although employment requirements are not expected
to increase from 1966-75, many machine tool operators
will be needed to fill openings resulting from the transfer
of operators to other occupations, or from deaths,

Welders and Oxygen and Arc Cutters39

Current Employmen t
About 460,000 welders and oxygen and arc cutters
were employed in the United States in 1966. Included in
the occupational classification are arc welders, arc
cutters, gas welders, combination welders, oxygen
cutters, and resistance welders.
About 350,000 welders and oxygen and arc cutters
were employed in manufacturing industries in 1966.
42




Large numbers were employed in the fabricated metal
products, primary metals, machinery, and transportation
equipment manufacturing industries. Of the approxi­
mately 110,000 welders and oxygen and arc cutters
employed in nonmanufacturing industries, about twothirds were employed in construction firms and estab39 (D.O.T. 810. through 819.887), Dictionary o f Occupa­
tional Titles, U.S. Department of Labor, 1966, 3d edition.

lishm ents performing miscellaneous repair services. The
rest were distributed widely among other nonm anu­
facturing industries.

Training
Welders and oxygen and arc cutters acquire their
training in a variety o f ways. Most o f them learn their
trade on the job. Generally, several years o f training are
required to becom e a skilled manual arc and gas welder;
however, manual jobs that are performed by resistance
welding machine operators and oxygen and arc cutters
usually are learned in a few weeks on the job.
Some manual welders acquire their training in formal
apprenticeship programs offered by a few large
com panies. Also, the U.S. Department o f the Navy, at
several o f its installations, conducts 4-year welding
apprenticeship programs for its civilian em ployees. In
addition, some welders receive training through
programs operated under provisions o f the Manpower
Developm ent and Training Act o f 1962; in 1966, more
than 8,300 persons were enrolled in MDTA institutional
programs for welders.
Welders may be required to pass an exam ination
before being assigned to work where the strength o f the
w eld is a highly critical factor. The test may be given by
an em ployer, a municipal agency, a private agency
designated by local government inspection authorities,
or a Naval facility. Certification tests also are given to
welders on some construction jobs, or to those who may
be engaged in the fabrication or repair o f steam or other
pressure vessels where critical safety factors are involved.
In addition to certification, some localities require
welders to obtain a license before they can do certain
types o f outside construction work.
N ew developm ents in some manufacturing industries
are increasing the skill requirements o f welders, particu­
larly in fields such as atom ic energy or aerospace where
high standards o f reliability require more precise work.

Employment Trends and Outlook
Rising from about 250,000 to about 460,0 0 0 ,
em ploym ent o f welders and oxygen and arc cutters
increased nearly 85 percent betw een 1950 and 1966.
This em ploym ent growth resulted from the increasing
use o f the welding process in the metalworking
industries, as well as the general expansion o f these
industries during this period.
Em ploym ent requirements for welders and oxygen
and arc cutters are expected to increase to about
575,000 by 1975. The projected increase is based on the
favorable long-run outlook for metalworking industries
and the continuing wider use o f the welding process.
Many more manual welders will be needed for main­
tenance and repair work. In addition, the number o f
manual welders engaged in production work is expected
to increase in plants manufacturing structural-metal
products such as metal doors, boilers, and storage tanks.
The construction industry also will need an increasing
number o f welders as the use o f steel structures expands.
Em ploym ent o f resistance welders is expected to rise
because o f the increasing use o f the machine resistance­
welding process in activities such as the manufacture o f
m otor vehicles; aircraft and missiles; and light, stream­
lined railroad cars; however, the use o f faster and highly
autom ated welding machines will tend to lim it growth in
these occupations. Em ploym ent requirements for
oxygen and arc cutters also are expected to rise
primarily as a result o f the general expansion o f
metalworking activities; however, the increased use o f
oxygen-and arc-cutting machinery will tend to lim it the
growth o f this occupation.
In addition to manpower needs for occupational
growth, many welders and oxygen and arc cutters will be
needed to replace workers who transfer to other
occupations, or who die, retire, or leave the labor force
for other reasons during 1966-75. For exam ple, each
year, withdrawals from the labor force alone are
estim ated to number between 1.0 and 1.5 percent o f all
welders and oxygen and arc cutters.

Over-the-Road Truckdrivers40

Current Em ploym ent
About 620,000 over-the-road truckdrivers were
em ployed in the U nited States in 1966. Over-the-road
drivers are em ployed by private and for-hire carriers.




Private carriers are com panies, such as chain food stores
or manufacturing plants, which transport their ow n

43

goods. For-hire carriers are either com m on carriers
(trucking companies serving the general public) or
contract carriers (trucking firms hauling goods under
contract for certain com panies).

Training
Most over-the-road truckdrivers acquire their training
on the job. Long haul driving is considered a senior
driving job and m ost over-the-road truckdrivers have had
previous experience in local trucking. Beginners usually
enter this occupation by first driving small, light trucks;
after gaining experience, they get jobs driving the larger
and more com plicated trucks. Some also begin as helpers
to local truckdrivers. They assist in loading and
unloading trucks, and occasionally doing some relief
driving. Others obtain experience by working for an
inter-state bus com pany.
Regulations o f the Interstate Commerce Commission
establish m inim um qualifications for over-the-road
drivers. Drivers must be at least 21 years o f age,
able-bodies, have good hearing, and vision o f at least
2 0 /4 0 with or w ithout glasses. They must read and speak
English, have at least 1 year’s driving experience (which
may include driving private autom obiles), and a good
driving record. Most States require truckdrivers to have a
chauffeur’s license, which is a commercial driving permit
obtained from State Motor Vehicle Departments.
Applicants for over-the-road truckdrivers are required
to pass a physical exam ination. Many firms also give
written traffic and driving knowledge tests. Some
em ployers give tests to measure sharpness and field o f
vision, reaction tim e, ability to judge speed, and em o­
tional stability. The applicant is expected to dem on­
strate his ability to handle a vehicle o f the type and size
he will operate in regular service under a variety o f
driving conditions. A few States require such a test
before licensing a driver to operate a tractor-trailer
com bination.

Em ploym ent Trends and Outlook
Em ploym ent o f over-the-road truckdrivers increased
from 555,000 to about 620,000 between 1960 and

44




1966. This increase in em ploym ent is attributed to the
growing am ount o f intercity freight carried by trucks
and results from high levels o f business activity, the
geographic dispersion o f factories and warehouses, and
the location o f new businesses in areas where rail
facilities are nonexistent or extrem ely lim ited. Improve­
m ents on trailer design also have contributed to more
over-the-road trucking and make possible the long
distance shipping o f certain kinds o f freight such as
frozen foods and livestock.
Em ploym ent requirements for over-the-road truckdrivers are expected to reach approxim ately 1 m illion in
1975, about three-fifths above the 1966 level. Substan­
tial growth in the volum e o f intercity freight is expected
to result from continued increases in commercial and
industrial activity and continued decentralization o f
industry. Furthermore, the demand for trucking services
may increase as a result o f new trucking m ethods that
reduce handling and shipping time and, therefore, reduce
freight costs for small loads. One example is the
increasing use o f “double bottom s”—tw o trailers hitched
in tandem to a tractor. When tw o trailers are used, they
can be unhitched at the truck terminal and promptly
delivered to customers. This plan eliminates the need to
unpack a larger trailer, separate the contents, and repack
on local delivery trucks.
Some recent freight transportation innovations will
lim it the anticipated increase in trucking business and
over-the-road driver em ploym ent. For exam ple, the
m ovem ent o f highway trailer on railroad flat cars, ocean
vessels, and aircraft saves the cost o f driver, fuel, and
tractor.
In addition to manpower requirements for occupa­
tional growth, many over-the-road truckdrivers will be
needed during 1966-75 to replace workers who transfer
to other occupations, or who die, retire, or withdraw
from the labor force for other reasons. For exam ple,
each year, withdrawals from the labor force alone are
estim ated to number betw een 1.5 and 2.0 percent o f all
over-the-road truckdrivers.

LABO RERS41

Current Em ploym ent
Nearly 3.7 m illion laborers were em ployed in 1966,
30 percent o f whom were em ployed in manufacturing
establishm ents. About one-fifth o f all laborers worked in
the construction industry. Large numbers also were
em ployed in wholesale and retail and in transportation
work.

Training
A great am ount o f the work performed by laborers
requires little special training because it involves only
simple tasks, such as handling and moving materials. To
do such work, brief instruction com bined with a few
hours o f on-the-job training is sufficient. However, since
w o rk processes are becom ing more and more
m echanized, many laborers need longer periods o f
on-the-job experience and instruction to operate various
types o f power-operated equipm ent and to learn new
techniques.

Em ploym ent Trends and Outlook
Em ploym ent o f laborers increased from 3.5 million in
1947 to nearly 4 m illion in 1951. Between 1951 and
1961, em ploym ent decreased to below 3.5 million and
then rose to 3.7 m illion in 1966. From 1947-66, growth




in em ploym ent o f laborers was lim ited by the increasing
use o f m echanized equipm ent to replace manual labor in
operations such as loading and unloading, digging,
hoisting, and woodchopping.
Em ploym ent requirements for laborers are expected
to change very little betw een 1966 and 1975, in spite o f
the rapid rise anticipated in manufacturing and construct i o n activity. Increasing demand for laborers is
expected to be about offset by the continuing substitu­
tion o f mechanical equipm ent for manual labor. For
exam ple, power-driven equipm ent such as forklift
trucks, derricks, cranes, hoists, and conveyor belts will
take over more and more materials handling work in
factories, at freight terminals, and in warehouses. Other
power-driven machines will do excavating, ditch digging,
and similar work. In addition, integrated system s o f
processing and materials handling equipm ent, a more
advanced step in autom ation, will be installed in an
increasing number o f plants in the years ahead.
Although em ploym ent requirements for laborers are
not expected to increase from 1966-75, many laborers
will be needed to replace those who transfer to other
occupations, or who die, retire, or withdraw from the
labor force for other reasons. For exam ple, each year,
withdrawals from the labor force alone are estim ated to
number betw een 1.5 and 2.0 percent o f all laborers.

Nearly 9.7 m illion service workers were em ployed in
the United States in 1966. Service workers include a
wide range o f diverse occupations such as elevator
operator, policem an, fireman, cleaning wom an, golf
caddy, theater usher, barber, and laundress. Nearly
one-fourth o f all service workers were em ployed in
private households and performed homemaking tasks
such as cleaning, dishwashing, laundering, and preparing
and serving meals. W omen account for about 97 o f every
100 private household workers.
About three-fifths o f the more than 7 million service
workers em ployed outside private hom es in 1966
worked for one o f the various service industries. These
workers included thousands o f nurse aids and other
attendants in hospitals; cooks and kitchen workers in
hospitals and schools; maids and porters in hotels; and
barbers and beauty operators. In trade, m ost service
workers were cooks, kitchen workers, fountain and
counter workers, or waiters and waitresses in restaurants,
drugstores, and other retail establishments where food is
served. In government, many service workers were
em ployed as firefighters, policem en, and other law
enforcem ent officers.

Training
Service workers acquire their training in a variety o f
ways because o f the many different occupations that
make up the group. Many occupations, including general
m aid, waiter, waitress, elevator operator, and hotel
bellm an, do n ot require formal education; workers in
these occupations generally receive only short-term
on-the-job instruction. Other service workers such as
barbers and beauty operators acquire their training in
vocational schools. Some service occupations, such as
FBI agent, require college or university training. Police­
m en and firemen receive intensive on-the-job training
and classroom instruction. Nurse aids receive on-the-job
training that may last from a few weeks to a few m onths
and generally includes some formal training. Some are
trained in vocational schools.

Em ploym ent Trends and Outlook
Em ploym ent o f service workers increased nearly
one-half betw een 1950 and 1966 and rose from about

46




6.5 million to nearly 9.7 m illion. The major factors
underlying the growth in em ploym ent o f service workers
during this period were a rising population, expanding
business activity, increasing leisure tim e, and increasing
disposable personal incom e.
Em ploym ent requirements for service workers are
expected to reach about 12.7 m illion in 1975, about 30
percent above the 1966 level. The occupations within
the service group, however, will grow at different
rates—some growing rapidly, others m oderately, and a
few actually declining.
The greatest growth in manpower requirements is
expected to be for policem en and other protective
service workers; nurse aids, orderlies, and attendants;
beauty operators; cooks, waiters, and others who pre­
pare and serve meals outside private hom es; and janitors,
caretakers, and building cleaners. Some o f the main
factors that are expected to increase requirements for
these occupations are the rising demand for hospital and
other medical care resulting from increases in population
and the ability to pay for health care; the greater need
for protective services as urbanization continues and
cities becom e more crowded; and the more frequent use
o f restaurants, beauty parlors, and other services as
incom e levels rise and as more wives take jobs outside
the hom e.
The nature o f the service occupations, especially the
necessity for person-to-person contact, lim its the ap­
plication o f laborsaving technological innovations. Over­
all, the number o f jobs eliminated by laborsaving
technological innovations, such as autom atic dry cleaning
machines, autom atic elevators, and computer controlled
traffic signals, is expected to be small compared with the
number o f new jobs created as the demand for service
workers expands.
In addition to manpower requirements for occupa­
tional growth, m any service workers will be needed to
replace workers w ho transfer to other occupations, or
who die, retire, or withdraw from the labor force for
other reasons during 1966-75. For exam ple, each year,
withdrawals from the labor force alone are estim ated to
number between 3.5 and 4.0 percent o f all service
workers.

Municipal Policemen42

Current Em ploym ent

Em ploym ent Trends and Outlook

Nearly 195,000 policem en and policew om en were
em ployed by city and tow n police departments in 1966.
Policewom en constituted less than 5 percent o f the
total, and worked mainly in large cities.

Municipal police em ploym ent increased about onehalf betw een 1950 and 1966, from about 130,000 to
nearly 195,000. The major factor contributing to this
em ploym ent growth was increasing population, particu­
larly urban population; greater protective service needs
resulted.
Em ploym ent requirements for municipal policem en
are expected to reach almost 250,0 0 0 in 1975, more
than one-fourth above the 1966 level based primarily on
expected further increases in population. Officers who
have specialized training will be needed as engineering
techniques are applied to traffic planning and control
and social work techniques are used to prevent crime.
On the other hand, relatively fewer officers will be
required for routine assignments such as directing traffic
because autom atic signal lights will be used to control
traffic at busy intersections.
In addition to manpower needs for occupational
growth during 1966-75, many more municipal police­
m en will be required to replace workers w ho transfer to
other occupations, or who leave the labor force because
o f death, retirem ent, or other reasons. For exam ple,
each year, the number leaving the labor force alone is
estim ated to be about 1.5 percent o f all municipal
policem en.

Training
Municipal policem en usually learn their jobs in
training programs offered by the police department. In
large city police departments, extensive training may
extend over several weeks or a few m onths. The training
generally included classroom instruction on State laws
and local ordinances and in the procedure to be follow ed
in accident investigation, patrol, traffic control, and
other police work. Recruits leam how to use a gun,
defend themselves from attack, administer first aid, and
deal with other emergencies. In many small com ­
m unities, instruction usually is given informally as
recruits work with experienced officers.
Som e municipal policem en and policew om en obtain
their training in colleges and universities. More than 100
colleges and universities offer programs in law enforce­
m ent. Most cities require municipal policem en to
com plete high school; however, some cities accept men
w ho have not graduated from high school, particularly if
they have worked in a field related to law enforcem ent,
such as military police training.

Private Household Workers43

Current Em ploym ent
About 2.3 m illion private household workers were
em ployed in 1966, nearly all o f w hom were w om en.
Included in the occupation classification are general
maids, m other’s helpers, personal maids, nursemaids,
infants’ nurses, babysitters, hom e housekeepers, working
housekeepers, cooks, laundresses, com panions, governes­
ses, handym en, caretakers, housem en, valets, butlers,
and chauffeurs.

Training
For m ost private household workers there are no
formal training requirements. Those who do housework
may acquire their skills while helping w ith the house­




work in their ow n hom es. Some persons acquire such
skills by working for about a year as an assistant to an
experienced dom estic worker or housew ife. A few
acquire skills beyond the level ordinarily reached in the
hom e through the com pletion o f hom e econom ics
courses offered in high schools, vocational schools, and
junior colleges, or in training courses sponsored by
Federal agencies, State em ploym ent service offices, and
local welfare departments. Some private household
workers have received training through programs estab­
lished under the Manpower D evelopm ent and Training
Act o f 1962.

Labor, 1966, 3d edition.
47

Som e private household workers such as handymen,
chauffeurs, and cooks acquire training through
experience in related work. For exam ple, some gardeners
have acquired their skills by working for landscaping
firms. In contrast to m ost other private household
occupations, governesses generally need experience and a
broad educational background in the arts to teach young
children.

Em ploym ent Trends and Outlook
Em ploym ent o f private household workers increased
more than one-fifth betw een 1950 and 1966, from
approxim ately 1.9 m illion to about 2.3 m illion. The
need for the services o f these workers has risen because
o f the growing population, increasing number o f house­
holds, and increasing number o f housewives working

outside o f the hom e. Rising family incom es also contri­
buted to the increase in em ploym ent o f private house­
hold workers.
Em ploym ent requirements for private household
workers are expected to reach about 2.7 m illion in 1975,
one-eighth above the 1966 level. The same factors that
stimulated em ploym ent growth o f these workers
between 1950 and 1966 are expected to continue to
boost demand for them through the m id-1970’s.
In addition to manpower requirements for occupa­
tional growth, many thousands o f private household
workers will be needed to replace workers who transfer
to other occupations, or withdraw from the labor force
because o f death, retirement, or other reasons during
1966-75. For exam ple, each year withdrawals from the
labor force alone are estim ated to number betw een 5.0
and 6.0 percent o f all household workers.

Cooks and Chefs44

Current Em ployment
About 650,000 chefs and cooks were em ployed in
the United States in 1966. Included in this occupation
classification are pastry cooks, fry cooks, roast cooks,
vegetable cooks, and short order cooks.
More than one-half o f all cooks and chefs are
em ployed in restaurants. About one-third are em ployed
in public and private schools, hotels, and hospitals. The
rest work in a variety o f establishments such as railroad
dining cars, ocean liners, private clubs, manufacturing
plants, and government agencies.

Training
Most cooks, especially those who work in small eating
places, acquire their skills on the job while em ployed as
kitchen helpers. Others receive training through ap­
prenticeship programs conducted by some large hotels
and restaurants for their new em ployees.
Som e cooks and chefs are trained in specialized
courses in restaurant cooking offered in vocational high
schools. Other courses, open in some cases only to high
school graduates, range from a few m onths to 2 years or
more in length. They are given under the auspices of
restaurant associations, hotel management groups, and
trade unions, and in technical schools and colleges. Also,
the Federal Government, under provisions o f the Man­
power Developm ent and Training Act o f 1962, spon­
sored training programs for cooks; in 1966, about 3,100
48




persons were enrolled in MDTA institutional programs
for these workers.
Although the curriculums vary among the different
training programs, usually a major part o f each student’s
tim e is spent in learning professional food preparation
through actual practice in well-equipped kitchens. The
student receives instruction in baking, broiling, and
other m ethods o f preparing food, and in the use and care
o f kitchen equipm ent. Instructions also may be given in
selecting and storing food, determining the size o f
individual portions, planning menus, buying food sup­
plies in quantity, hotel and restaurant sanitation, and the
public health aspects o f food handling.

Em ployment Trends and Outlook
Rising from 4 3 5,0 0 0 to about 650,000, em ploym ent
o f cooks and chefs increased nearly one-half between
1950 and 1966. This substantial increase reflects the
expansion in serving meals away from the hom e.
Population growth, higher incom e levels, increased
travel, and larger numbers o f housewives em ployed
outside o f the hom e have stimulated the increase.
Em ploym ent requirements for chefs and cooks are
expected to rise to about 860,000 in 1975, nearly
one-third above the 1966 level. This projected increase is
based on the continued expansion o f the business o f

serving meals away from home. Population growth and
the relatively rapid increases in the size of groups
customarily eating meals away from home—
young
people entering jobs for the first time, women taking
employment outside of their homes, and students
attending schools and colleges— among the factors
are
expected to increase requirements for cooks and chefs.
Greater requirements for these workers also are expected
in hospitals and other institutions where an increase is
foreseen in the number of patients, attendants, and
others who regularly eat meals prepared on the premises.

In addition, rising income levels are increasing travel for
business and pleasure and are expected to result in larger
numbers of people who patronize eating places.
In addition to manpower requirements for occupa­
tional growth, many cooks and chefs will be needed to
replace workers who transfer to other occupations, or
who die, retire, or otherwise leave the labor force during
1966-75. For example, each year, withdrawals from the
labor force alone are estimated to number between 3.5
and 4.0 percent of all cooks and chefs.

Waiters and Waitresses45
Current E m ploym en t

E m ploym en t Trends and O utlook

About 950,000 waiters and waitresses were employed
in the United States in 1966, about 88 percent of whom
were waitresses.
Approximately four-fifths of all waiters and wait­
resses are employed in restaurants, drug stores, and other
retail establishments that serve food to the general
public. The rest are employed in hotels and other
lodging places, in both private and public educational
institutions, and in entertainment and recreational serv­
ice establishments.

Employment of waiters and waitresses increased 45
percent between 1950 and 1966, from 658,000 to about
950,000. This increase stemmed from a great expansion
in serving meals away from home. The factors responsi­
ble for expanding restaurant services included a growing
population; rising income levels; increasing travel, both
for business and pleasure; and increasing numbers of
housewives employed outside of the home.
Employment requirements for waiters and waitresses
are expected to reach more than 1.2 million by 1975,
about one-fourth above the 1966 level. The factors that

Farm Workers46
Current E m ploym en t

About 3.9 million farm workers—
including farmers,
farm managers, laborers, and foremen— employed
were
in the United States in 1966. Over half of all farm
workers were farmers and farm managers.
Training

Many farm workers obtain their skills by living on a
farm. Many farmers also take vocational training avail­
able under federally assisted programs. Such training is
offered in full-time programs supervised by teachers who
are agriculture college graduates; in short courses for
young farmers offered during the day on subjects such as
farm planning, farm layout, farm structure, plant breed­
ing, and pest control; and in adult evening classes (or day
classes in off seasons) that provide instruction in areas
such as conservation and crop and livestock production.
Organized groups such as the Future Farmers of America
and the 4-H Clubs also train young farm people.
E m ploym en t Trends and O utlook

Employment requirements for farm workers de­
creased 52 percent from about 8.1 million in 1947 to
approximately 3.9 million in 1966. Farmers and farm
managers declined faster than the group as a whole, from
nearly 5 million in 1947 to 2.1 million in 1966, a 60
percent decrease. Farm laborers and foremen declined
more than two-fifths, from 3.1 million workers in 1947
to 1.8 million in 1966. The decline in farm workers
occurred despite a substantial increase in farm output
over the same period. The major factors that caused the
decline in employment requirements for farm workers
were the increased size and efficiency of farms, and the
mechanization of many farm operations. In 1947, one
farm worker produced enough food and fiber for himself
and 14 others; in 1966, he produced enough for himself
and 31 others.
Employment requirements for farm workers are
expected to decrease from 4.3 million to about 3.4

50




million between 1966 and 1975, in part because of
continued improvements in farm technology. For exam­
ple, improved fertilizers, seeds, and feed will permit
farmers to increase production without corresponding
increased employment. Improved mechanical harvesters
for vegetables and fruits will decrease the need for
seasonal or other hired labor. Innovations in livestock
and poultry feeding and improved milking systems will
allow more efficient handling of a greater volume of
production. The expected development of automatic
packing, inspection, and sorting systems for fruits,
vegetables, and other farm products also will reduce
employment requirements for farm workers.
Employment requirements for farm workers also are
expected to decline because of the continued trend
toward larger and more efficient farms. Farmers and
farm managers are expected to continue to be most
affected by the decline in the number of small farms,
and requirements for these workers are expected to
continue to decline faster than for farm laborers and
foremen.
Output of farm products is expected to continue to
increase in the years ahead. However, unlike other
segments of the economy, farm output is not expected
to be stimulated by significant increases in per capita
consumption of its products. Increases in domestic farm
production will result primarily from the increased
demand as the population grows.
Despite declining manpower requirements for farm
workers during 1966-75, many thousands of farm
workers will be needed to replace those who transfer to
other occupations, or withdraw from the labor force
because of death, retirement, or other reasons. For
example, each year, withdrawals from the labor force
alone are estimated to number between 2.0 and 3.0
percent of all farm workers.
