This report describes the employment outcomes of youth who left foster care after their eighteenth birthday in California, Illinois, and South Carolina in the 1990s. It examines their employment stability and earnings, and compares their outcomes to youth who were reunified with their parents prior to their eighteenth birthday and to youth from low-income families. Overall it finds that youth who age out of foster care tend to be underemployed, earn low wages, and progress slowly in the labour market.
