Research shows that transitions out of public institutions or systems often lead to homelessness among young people. These individuals have little control over when they exit, and the timing is often arbitrary, failing to consider their developmental needs, life skills, and financial stability. Structural barriers, such as high housing costs, low wages, and age discrimination, further increase their vulnerability. As a result, many young people face housing instability, poverty, food insecurity, and unsafe living conditions. They also struggle to reconnect with their communities, rebuild social support networks, and pursue education, employment, or training. Without adequate assistance, living independently becomes a significant challenge. While youths leaving in-patient health or mental health care, as well as correctional facilities, encounter major difficulties, one of the most critical transitions occurs when young people exit the child protection system. This collection on the Homeless Hub focuses on the unique challenges faced by youths aging out of care.
