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 12.3 jobs from ages 18 to 52. These baby boomers held an average of 5.7 jobs while ages 18 to 24. The average fell to 4.5 jobs from ages 25 to 34, to 2.9 jobs from ages 35 to 44, and to 1.9 jobs from ages 45 to 52. Jobs that span more than one age group were counted once in each age group, so the overall average number of jobs held from ages 18 to 52 is less than the sum of the number of jobs across the individual age groups. (See table 1.) Although job duration tended to be longer the older a worker was when starting the job, these baby boomers continued to have large numbers of short-duration jobs. Among jobs started by 35 to 44 year olds, 36 percent ended in less than a year, and 75 percent ended in fewer than 5 years. (See table 2.) On average, individuals were employed during 78 percent of the weeks from ages 18 to 52. Generally, men spent a larger percent of weeks employed than did women (84 percent versus 72 percent). Women spent much more time out of the labor force (24 percent of weeks) than did men (11 percent of weeks). (See table 3.) The average annual percent growth in inflation-adjusted hourly earnings was highest during a worker's late teens and early twenties. Growth rates in earnings generally were higher for workers with a bachelor's degree or higher than for workers with less education. (See table 5.)-2-Number of Jobs Held Individuals held an average of 12.3 jobs from ages 18 to 52, with nearly half of these jobs held before age 25. In this news release, 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 12.5 jobs and women held 12.1 jobs from ages 18 to 52. Men held 5.9 jobs from ages 18 to 24, compared with 1.9 jobs from ages 45 to 52. The reduction in the average number of jobs held in successive age groups was similar for women. (See table 1.) Chart 1 shows the cumulative number of jobs held from ages 18 to 52, by sex and age. The decline in the slope of these curves indicates a decrease in the rate at which workers change jobs as they age. On average, men without a high school diploma held 13.3 jobs from ages 18 to 52, while men with a bachelor's degree and higher held 11.6 jobs between these ages. In contrast, women without a high school diploma held 9.9 jobs from ages 18 to 52, while women with a bachelor's degree and higher held 13.1 jobs between these ages.
