My goal is to understand persistence of employment in the information technology sector over age groups. For example, for the person who enters IT at age 21, are they still employed in that sector at 31? 41? 51? 61? And, to put all this in context, how does the rate of career persistence compare to other U.S. sectors like finance, real estate, trades, health care, sales, education, etc?
Before I try to start from scratch, does this duplicate previous work?
