In 1979, the Labor Department began to track the careers of young men and women born between 1957 to 1964. The survey has tracked the same 10,000 people who were between 14 and 22 when they were first interviewed and are now 47 to 56. New results of this survey released Tuesday, covering 1978 to 2012, provide unique insight into the careers of the youngest baby boomers, the generation born after World War II.
