Individuals born in the latter years of the baby boom held an average of 11 jobs from age 18 to age 44, with the majority of the jobs being held before age 27. These baby boomers (who were born in the years 1957 to 1964) held an average of 4.4 jobs while they were between the ages of 18 and 22.
The average number of jobs fell to 3.2 while these persons were ages 23 to 27 and to 2.6 while they were ages 28 to 32. These individuals held an average of 2.4 jobs while they were ages 33 to 38 and 2.0 jobs while they were ages 39 to 44.
On average, men held 11.4 jobs and women held 10.7 jobs from age 18 to age 44. Men held 4.5 jobs from age 18 to age 22, compared with 2.0 jobs from age 39 to age 44. The reduction in the average number of jobs held in successive age groups was similar for women.
