From the U.S. Bureau of Bureau of Labor Statistics: “The average person who now is between ages 47 and 56 has held 11.7 jobs since turning 18. Nearly half of those jobs were held before age 25, but it was common for people to hold three jobs from age 25 to 29, two-and-a-half jobs from age 30 to 34 and two jobs from age 30 to 39.”
