Union Members in 1997

The share of workers who were union members continued to decline in
1997, the U.S. Department of Labor’s Bureau of Labor Statistics reported
today. Union members accounted for 14.1 percent of wage and salary
employment in 1997, down from 14.5 percent in 1996. The union membership
rate has fallen steadily from 20.1 percent in 1983, the first year for
which comparable data are available.
About three-fifths of the 16.1 million union members in 1997 were in
private nonagricultural industries, where they constituted 9.8 percent of
wage and salary employment. About 6.7 million union members worked in
government (federal, state, and local), accounting for 37.2 percent of
government employment.
Membership by industry and occupation
Among the private nonagricultural industries, transportation and
public utilities had the highest unionization rate (26.0 percent), followed
by construction (18.6 percent). Manufacturing and mining also had aboveaverage unionization rates, at 16.3 and 13.9 percent, respectively. In the
other industry groups, the proportion of workers who were members of unions
ranged from about 2.1 to 5.8 percent. (See table 3.)
Among the occupational groups, the unionization rate was highest among
those working in protective service jobs (39.9 percent). This group
includes many government workers such as police officers and firefighters.
Union membership rates also were high in professional specialty; precision
production, craft, and repair; and operator, fabricator, and laborer
occupations. Rates were lowest in sales and in farming, forestry, and
fishing occupations, at 4.3 and 4.6 percent, respectively. (See table 3.)
Demographic characteristics of union members
Union membership was higher among men (16.3 percent) than women (11.6
percent) and higher among blacks (17.9 percent) than either whites (13.6
percent) or Hispanics (11.8 percent). Within these groups, black men
continued to have the highest union membership rate (20.2 percent), while

white and Hispanic women had the lowest rates (both about 11 percent).
Workers ages 35 to 64 were more likely to be members of unions than either
their younger or older counterparts. Full-time workers were more than
twice as likely as part timers to be union members. (See table 1.)
Union representation of nonmembers
About 1.8 million wage and salary workers were represented at their
work place by a union in 1997, while not being union members themselves.
About half of these workers were employed in government.
- 2 Earnings
In 1997, union members had median usual weekly earnings of $640
compared with a median of $478 for wage and salary employees not
represented by unions. (See table 2.) This difference reflects a variety
of influences in addition to coverage by a collective bargaining agreement,
including variations in the distributions of union members and nonunion
employees by occupation, industry, firm size, or geographic region. (For a
discussion of the problem of differentiating between the influence of
unionization status and the influence of other worker characteristics on
employee earnings, see Kay E. Anderson, Philip M. Doyle, and Albert E.
Schwenk, "Measuring union-nonunion earnings differences," Monthly Labor
Review, June 1990, pp. 26-38.) The union-nonunion earnings ratio was
greater for women than for men and for blacks and Hispanics than for
whites.
Technical Note

The estimates in this release are obtained from the Current Population
Survey (CPS), which provides the basic information on the labor force,
employment, and unemployment. The survey is conducted monthly for the
Bureau of Labor Statistics by the Bureau of the Census from a
scientifically selected national sample of about 50,000 households. The
union membership and earnings data are tabulated from one-quarter of the
CPS monthly sample and are limited to wage and salary workers. Excluded
are all self-employed workers.
Information in this release will be made available to sensory impaired
individuals upon request. Voice phone: 202-606-7828, TDD phone:
202-606-5897, TDD message referral phone number: 1-800-326-2577.
Reliability

In any sample survey, variations in the data can occur by chance
because a sample, rather than the whole population, is surveyed. The
standard error is a measure of such potential variation. The chances are
about 68 out of 100 that an estimate from the survey differs from a figure
that would be obtained from a complete census by less than one standard
error. The chances are about 90 out of 100 that such a difference would be
less than 1.6 standard errors.
For a full discussion of the reliability of data from the CPS and
information on estimating standard errors, see the "Explanatory Notes and
Estimates of Error" section of the February 1994 and subsequent issues of
Employment and Earnings.
Definitions
The principal definitions used in this release are described briefly
below.
Union members. Data refer to members of a labor union or an employee
association similar to a union.
Represented by unions. Data refer to union members, as well as
workers who have no union affiliation but whose jobs are covered by a union
or an employee association contract.
Usual weekly earnings. Data represent earnings before taxes and other
deductions and include any overtime pay, commissions, or tips usually
received (at the main job in the case of multiple jobholders). Prior to
1994, respondents were asked how much they usually earned per week. Since
January 1994, respondents have been asked to identify the easiest way for
them to report earnings (hourly, weekly, biweekly, twice monthly, monthly,
annually, other) and how much they usually earn in the reported time
period. Earnings reported on a basis other than weekly are converted to a
weekly equivalent. The term "usual" is as perceived by the respondent. If
the respondent asks for a definition of usual, interviewers are instructed
to define the term as more than half the weeks worked during the past 4 or
5 months.
Median earnings. The median is the amount which divides a given
earnings distribution into two equal groups, one having earnings above the
median and the other having earnings below the median.
The estimating procedure places each reported or calculated weekly
earnings value into $50-wide intervals which are centered around multiples
of $50. The actual value is estimated through the linear interpolation of
the interval in which the median lies.

Wage and salary workers. Workers who receive wages, salaries,
commissions, tips, payment in kind, or piece rates. The group includes
employees in both the private and public sectors but, for the purposes of
the union membership and earnings series, excludes all self-employed
persons, regardless of whether or not their businesses are incorporated.
Full-time workers. Workers who usually work 35 hours or more per week
at their sole or principal job.
Part-time workers. Workers who usually work fewer than 35 hours per
week at their sole or principal job.
Hispanic origin. Refers to persons who are of Mexican, Puerto Rican,
Cuban, Central or South American, or other Hispanic origin or descent.
Persons of Hispanic origin may be of any race; hence, they are included in
the numbers for the white and black populations.

2 Data refer to members of a labor union or an employee association similar to a union as well as workers who report no
union affiliation but whose jobs are covered by a union or an employee association contract.
3 The distinction between full- and part-time workers is based on hours usually worked. Beginning in 1994, these data will
not sum to totals because full- or part-time status on the principal job is not identifiable for a small number of multiple
jobholders.
NOTE:
Data refer to the sole or principal job of full- and part-time workers. Excluded are self-employed workers
whose businesses are incorporated although they technically qualify as wage and salary workers. Detail for the above race
and Hispanic-origin groups will not sum to totals because data for the "other races" group are not presented and Hispanics

are included in both the white and black population groups. Beginning in January 1997, data reflect revised population
controls used in the household survey.
