In this paper, we document the continuing decline in employment and labor force participation of black men between the ages of 16 and 34 who have a high school education or less. We explore the extent to which these trends can be accounted for in recent years by two fairly new developments: (1) The dramatic growth in the number of young black men who have been incarcerated; and (2) strengthened enforcement of child support policies. We use micro-level data from the Current Population Survey Outgoing Rotation Groups (CPS-ORG), along with state-level data over time on incarceration rates and child support enforcement, to test these hypotheses. Our results indicate that post-incarceration effects and child support policies both contribute to the decline in employment activity among young black less-educated men in the past two decades, especially among those age 25-34.
