NUMBER OF JOBS HELD, LABOR MARKET ACTIVITY, AND

EARNINGS GROWTH AMONG THE YOUNGEST BABY BOOMERS:

RESULTS FROM A LONGITUDINAL SURVEY

The average person born in the later years of the baby boom held 10.5 jobs from age 18 to age 40,

according to the Bureau of Labor Statistics of the U.S. Department of Labor. Nearly three-fifths of these

jobs were held from ages 18 to 25.

These findings are from the National Longitudinal Survey of Youth 1979, a survey of 9,964 men and

women who were ages 14 to 22 when first interviewed in 1979 and ages 39 to 48 when interviewed most

recently in 2004-05. These respondents were born in the years 1957 to 1964, the later years of the “baby

boom” that occurred in the United States from 1946 to 1964. The survey spans a quarter century and provides information on work and nonwork experiences, training, schooling, income and assets, health conditions, and other characteristics. The information provided by respondents, who were interviewed annually

from 1979 to 1994 and biennially since 1994, can be considered representative of all men and women born

in the late 1950s and early 1960s and living in the United States when the survey began in 1979.

This release of the latest data from the longitudinal survey focuses on the number of jobs held, job duration, labor force participation, and earnings growth. Highlights from the survey include:

 • Individuals born from 1957 to 1964 held an average of 10.5 jobs from ages 18 to 40. These baby

boomers held an average of 3.8 jobs while ages 18 to 21. The average fell to 3.0 jobs while ages 22

to 25 and to 2.0 jobs from ages 36 to 40. Jobs that span more than one age group were counted

once in each age group, so the overall average number of jobs held from age 18 to age 40 is less than

the sum of the number of jobs across the individual age groups.

 • Although job duration tends to be longer the older a worker is when starting the job, these baby

boomers continued to have large numbers of short-duration jobs even as they approached middle age.

Among jobs started by workers when they were ages 36 to 40, 36 percent ended in less than a year

and 72 percent ended in fewer than 5 years.

 • The average person was employed during 77 percent of the weeks from age 18 to age 40. Generally,

men spent a larger percent of weeks employed than did women (85 versus 70 percent). Women spent

much more time out of the labor force (26 percent of weeks) than did men (10 percent of weeks).

 • The annual percent growth in inflation-adjusted hourly earnings was fastest when workers were in their

late teens and early twenties. Growth rates in earnings generally were higher for college graduates than

for workers with less education.

Number of Jobs Held

Individuals held an average of 10.5 jobs from ages 18 to 40, with the majority of the jobs being held before age 31. In this report, a job is defined as an uninterrupted period of work with a particular employer.

(See the Technical Note for additional information on the definition of a job.) On average, men held 10.7

jobs and women held 10.3 jobs from age 18 to age 40. Men held 3.9 jobs from age 18 to age 21 compared with 2.1 jobs from age 36 to age 40. The reduction in the average number of jobs held in successive

age groups was similar for women. (See table 1.)

On average, college-educated women held more jobs than women without a college degree and also held

more jobs than college-educated men. Women with a college degree held 11.2 jobs from ages 18 to 40 compared to 10.4 jobs for similarly educated men. Women with less than a high school diploma held an average

of 8.6 jobs. Men without a high school diploma held 12.0 jobs from ages 18 to 40, a higher average than

men or women with more education.

Differences in the number of jobs held also are apparent between race and ethnicity groups. From age

18 to age 40, whites held more jobs than either blacks or Hispanics or Latinos. The difference is most pronounced at younger ages. These differences in racial and ethnic groups disappeared at older ages; from ages

36 to 40, whites, blacks, and Hispanics or Latinos all held an average of about 2.0 jobs.

Duration of Employment Relationships

The length of time a worker remains with the same employer increases with the age at which the worker

began the job. Of the jobs that workers began when they were ages 18 to 21, 73 percent of those jobs

ended in less than a year and 95 percent ended in fewer than 5 years. Among jobs started by workers

when they were ages 36 to 40, 36 percent ended in less than a year and 72 percent ended in fewer than 5

years. (See table 2.)

Percent of Weeks Employed, Unemployed, and Not in the Labor Force

On average, the baby boomers represented by the survey sample were employed during 77 percent of

all the weeks occurring from age 18 to age 40. They were unemployed—that is, without jobs but actively

seeking work—5 percent of the weeks. They were not in the labor force—that is, neither working nor

seeking work—18 percent of the weeks. (See table 3.)

The amount of time spent employed differs substantially between educational-attainment groups, especially

among blacks and Hispanics or Latinos. Blacks with less than a high school diploma (as of the 2004-05 survey) spent 54 percent of weeks employed and 34 percent of weeks out of the labor force from age 18 to

age 40. By comparison, black high school graduates spent 67 percent of weeks employed and 23 percent

of weeks out of the labor force. Hispanic or Latino high school dropouts spent 60 percent of weeks employed compared with 72 percent of weeks for Hispanic or Latino high school graduates. White high school

dropouts spent 69 percent of weeks employed and white high school graduates spent 80 percent of weeks

employed. Among college graduates, there was little difference between racial and ethnic groups in labor

market attachment; each group spent 80 to 82 percent of weeks employed and 15 to 16 percent of weeks

out of the labor force.
3

The amount of time spent in the labor force also differs by sex, with women at every educational level

and at every age spending fewer weeks in the labor force than men. Men with less than a high school

diploma spent 77 percent of weeks employed from age 18 to age 40. These men also spent 9 percent of

weeks unemployed. By comparison, women with less than a high school diploma spent just 48 percent of

weeks employed and 6 percent of weeks unemployed from age 18 to age 40. Women without a high school

diploma spent nearly as much time out of the labor force (46 percent of weeks) as they did employed (48

percent of weeks). The differences between men and women in labor force attachment were much smaller

among those with a bachelor’s degree or more education, but men still spent a larger proportion of weeks

employed than did women (85 versus 78 percent).

Labor force attachment is related to age for both men and women, with the percent of weeks employed

increasing and the percent of weeks unemployed or not in the labor force falling as individuals grow older.

From ages 18 to 21, men spent 22 percent of weeks out of the labor force and women spent 34 percent of

weeks out of the labor force. This age range is a period when large proportions of men and women attend

college or receive vocational training and, as a result, they spend less time in the labor force than they eventually will. Indeed, from ages 36 to 40, these men spent only 6 percent of weeks out of the labor force and

women spent 21 percent of weeks out of the labor force. (See table 4.)

Like men, women were more likely to participate in the labor force as they aged, but the reduction in

the percent of weeks spent out of the labor force was much smaller among women than among men. After

age 21, women spent, on average, two and a half to four times as many weeks out of the labor force as men

of their same generation. Women in the age groups 22 to 25 and 26 to 30 each spent 26 percent of weeks

out of the labor force. Women ages 31 to 35 spent 24 percent of weeks out of the labor force and women

ages 36 to 40 spent 21 percent of weeks out of the labor force.

Percent Growth in Real Earnings

The inflation-adjusted earnings of workers increased most rapidly while they were young. Hourly earnings grew by an average of 6.3 percent per year from ages 18 to 21 and 6.5 percent per year from ages 22

to 25. The earnings growth rate slowed to 4.0 percent annually from age 26 to age 30, then to 3.6 percent

annually from age 31 to age 35. From ages 36 to 40, hourly earnings grew an average of 2.5 percent per

year. This pattern in earnings growth reflects, in part, the state of the U.S. economy during the years in which

survey participants were in each age group. For men and women in nearly every age category, growth rates

in inflation-adjusted hourly earnings generally were higher for workers with more education. (See table 5.)
Technical Note

The estimates in this release were obtained using data from

the first 21 rounds of the National Longitudinal Survey of

Youth 1979 (NLSY79). This survey is conducted by the Center

for Human Resource Research at The Ohio State University

and the National Opinion Research Center at the University of

Chicago under the direction and sponsorship of the U.S.

Department of Labor’s Bureau of Labor Statistics.

Sample

The NLSY79 is a nationally representative sample of 12,686

young men and women who were 14 to 22 years of age when

first surveyed in 1979. This survey sample was initially

composed of three subsamples:

• A cross-sectional sample of 6,111 youths that was

designed to represent the noninstitutionalized, civilian

population of young people living in the U.S. in 1979 and

born between January 1, 1957, and December 31, 1964

• A supplemental sample of 5,295 youths designed to

oversample noninstitutionalized, civilian black, Hispanic

or Latino, and economically disadvantaged nonblack,

non-Hispanic youths living in the U.S. in 1979 and born

between January 1, 1957, and December 31, 1964

• A military sample of 1,280 youths born between January 1,

1957, and December 31, 1961, and enlisted in the Army, Air

Force, Navy, or Marine Corps as of September 30, 1978

In 1985, the military sample was discontinued, and, in 1991,

the economically disadvantaged nonblack, non-Hispanic

youths were dropped from the supplemental sample. As a

result, the NLSY79 sample now includes 9,964 individuals from

the cross-sectional sample and the black and Hispanic or Latino

supplemental samples. (This sample size is not adjusted for

sample members who have died.)

Individuals were surveyed annually from 1979 to 1994 and

biennially since 1994. In 2004-05, 7,661 individuals responded

to the survey, for a retention rate of 77 percent. Only these

individuals are included in the estimates in this release. All

results are weighted using the 2004-05 survey weights that

correct for the oversampling, interview nonresponse, and

permanent attrition from the survey. When weighted, the

estimates represent all persons born in the years 1957 to 1964

and living in the U.S. when the survey began in 1979. Not

represented by the survey are U.S. immigrants who were born

from 1957 to 1964 and moved to the United States after 1979.

Work history data

The total number of jobs that people hold during their work

life is an easy concept to understand but a difficult one to

measure. Reliable estimates require a survey that interviews

the same people over the course of their entire work life and

also keeps track of all the jobs they ever held. The NLSY79

tracks the number of jobs that people have held, but the

respondents in this survey are still relatively young, ages 39

to 48 in 2004-05, and have many years of work life ahead of

them. As the cohort continues to age, however, more complete

information will become available.

A unique feature of the NLSY79 is that it collects the

beginning and ending dates of all jobs held by a respondent

so that a longitudinal history can be constructed of each

respondent’s work experiences. The NLSY79 work history data

provide a week-by-week work record of each respondent from

January 1, 1978, through the most recent survey date. These

data contain information on the respondent’s labor force status

each week, the usual hours worked per week at all jobs, and

earnings for all jobs. If a respondent worked at more than one

job in any week, hours and earnings are obtained for additional

jobs. When a respondent who missed one or more consecutive

survey rounds is interviewed again, he is asked to provide

information about all time since the last interview.

Interaction between time and age in a longitudinal

survey

Because the NLSY79 is a longitudinal survey, meaning the

same people are surveyed over time, the ages of the

respondents change with each survey round. It is important

to keep in mind this inherent link between the calendar years

and the ages of the respondents. For example, table 5 reports

earnings growth from age 22 to age 25. The youngest

respondents in the sample (birth year 1964) were these ages

during 1986-89, whereas the oldest respondents (birth year

1957) were these ages during 1979-82.

Although participants in the NLSY79 were ages 39 to 48

during the 2004-05 interviews, this release cover only the

period while the respondents were ages 18 to 40. The reason

for not including older ages is that the sample sizes were still

too small to provide statistically reliable estimates for age

groups older than 40. As the NLSY79 continues to be

administered and the respondents age, subsequent rounds of

the survey will enable analyses to be conducted for older age

groups.

As with age, the educational attainment of individuals may

change from year to year. In the tables and analysis presented

in this report, educational attainment is defined as of the 2004-05

survey. This definition is used even when data on age and

educational attainment are presented together. For example,

table 1 reports the number of jobs held during different age

categories. Suppose that a respondent had completed a

bachelor’s degree at age 28. That respondent would be

included in the “Bachelor’s degree and higher” educational

category in all age categories shown on the table, even though

he or she did not have a bachelor’s degree at any point from

age 18 to age 27.

Definitions

Job. A job is defined as an uninterrupted period of work

with a particular employer. Jobs are therefore employer-based,

not position-based. If a respondent indicates that he or she left
a job but in a subsequent survey returned to the same job, it

is counted as a new job. For example, if an individual worked

in a retail establishment during the summer, quit at the end of

summer to return to school, and then resumed working for the

same employer the following spring, this sequence would

count as two jobs, rather than one. For self-employed

workers, each “new” job is defined by the individuals

themselves.

Unemployment. If respondents indicate a gap between

employers, they are asked how many of those weeks they spent

searching for employment or on layoff. For that number of

weeks, they are considered unemployed. For the remaining

weeks, they are coded as not in the labor force. No probing

for intensity of job search is done.

Usual earnings. Respondents can report earnings over any

time frame (hour, day, week, month, year). For those who do

not report an hourly wage, one is constructed using usual

hours worked over that time frame. Wages greater than $100

per hour and less than $1 per hour were not included in the

analysis of earnings growth because the reported earnings

levels were almost certainly in error. For the same reason,

individuals who had inflation-adjusted earnings growth

greater than 100 percent were not included in the analysis.

These exclusions from the analysis affected 98 respondents.

Race and ethnicity groups. In this release, the findings are

reported for non-Hispanic whites, non-Hispanic blacks, and

Hispanics or Latinos. These three groups are mutually

exclusive but not exhaustive. Other race groups, which are

included in the overall totals, are not shown separately because

their representation in the survey sample is not sufficiently

large to provide statistically reliable estimates. In other BLS

publications, estimates usually are published for whites,

blacks, and Hispanics or Latinos, but these groups are not

mutually exclusive. The terms “Hispanic or Latino” are

considered to be an ethnicity group, and Hispanics or Latinos

can be of any race. Most other BLS publications include

Hispanics or Latinos in the white and black race groups in

addition to the Hispanic or Latino ethnicity group.

Table 3. Percent of weeks individuals were employed, unemployed, or not in the labor force from age 18

 The National Longitudinal Survey of Youth 1979 consists of men and women who were born in the years 1957-64 and were ages 14 to 

22 when first interviewed in 1979. These individuals were ages 39 to 48 in 2004-05. Educational attainment is defined as of the 2004-05 

survey. Race and Hispanic or Latino ethnicity groups are mutually exclusive but not exhaustive. Other race groups, which are included in 

the overall totals, are not shown separately because their representation in the survey sample is not sufficiently large to provide statistically 

reliable estimates.

 Totals do not add to 100 percent due to a small number of respondents whose employment status cannot be determined for all weeks.

Table 5. Average annual percent growth in inflation-adjusted hourly earnings from 1978-2004 by

educational attainment, sex, race, Hispanic or Latino ethnicity, and age

 The National Longitudinal Survey of Youth 1979 consists of men and women who were born in the years 1957-64 and were ages 

14 to 22 when first interviewed in 1979. These individuals were age 39 to 48 in 2004-05. Educational attainment is defined as of 

the 2004-05 survey. Race and Hispanic or Latino ethnicity groups are mutually exclusive but not exhaustive. Other race groups, 

which are included in the overall totals, are not shown separately because their representation in the survey sample is not sufficiently 

large to provide statistically reliable estimates.

Average annual percent growth in hourly earnings

 NOTE: The first column excludes individuals who turned age 18 before 1978. The last column excludes individuals who were

not yet age 41 when interviewed in 2004-05.

 The CPI-U-RS was used to adjust hourly earnings to 2004 dollars, prior to calculating the growth rates.

Characteristic
