Across the country, far too many young people age out of foster care into appalling circumstances. “Aging out” occurs when youth under the state’s custody are still in the foster care system when they reach either the age of majority or the end of extended foster care. Aging out refers to the moment in time when child welfare is no longer legally responsible for the youth, and the system abruptly stops providing services–usually when the youth turns either 18 or 21. Each year, thousands of youth age out of foster care, essentially legal orphans with no legal connection to family or a supportive network. Unfortunately, foster youth who go through the experience of aging out of foster care have statistically poor life prospects. Longitudinal studies across the country show very high rates of homelessness, incarceration, unemployment, and lack of access to health care among youth who aged out of foster care. These outcomes are disproportionately worse for Black, Native, and Brown youth, as well as queer and trans youth. This study is designed to understand the experiences of transition-age youth in their transition out of foster care and investigate: Why do poor outcomes for youth who age out of care persist? What are the current lived experiences of youth who age out of care? In what ways does child welfare continue to fall short for youth who age out of care?
