This document summarizes research on challenges faced by youth transitioning out of foster care. It finds that former foster youth often experience poorer outcomes than peers in areas like education, employment, housing, criminal justice involvement, and physical/mental health. Specifically, studies have found higher rates of homelessness, incarceration, early parenting, and less educational attainment among youth who aged out of foster care. Certain risk factors like a history of abuse, multiple placements, mental health issues, and running away from placements are associated with even greater difficulties.
