Collateral Costs: Incarceration’s Effect on Economic Mobility is a collaborative effort between Pew’s Economic Mobility Project and its Public Safety Performance Project (PSPP). The report examines the impact of incarceration on the economic opportunity and mobility of former inmates and their families. In addition, Collateral Costs examines the prison population by race/ethnicity and educational levels. It finds that incarceration reduces former inmates’ earnings by 40 percent and limits their future economic mobility and that one in every 28 children in America has a parent behind bars, up from one in 125 just 25 years ago. The report’s findings are based on research by Professor Bruce Western of Harvard University and Professor Becky Pettit of the University of Washington.
