Before the start of the pandemic, Michigan's public schools identified 4,763 homeless youth living independent of parental support. These youth are homeless--living outside, in shelters, or bouncing from couch to couch. They are estranged from their parents, usually due to abuse, neglect, or parents' struggles with addiction, mental health problems, or extreme poverty. Homeless youth experience multiple negative physical, mental, and behavioral health outcomes. Early intervention is imperative since the length of homelessness compounds and increases the risks of poor health outcomes, such as suicide attempts, sexual assault, exposure to violence, and human trafficking. One critical intervention that enables unaccompanied minors to connect to services and caring adults is safe and accessible shelter. Unfortunately, only a small proportion of unaccompanied minors in Michigan are accessing emergency shelter. This brief estimates the total number and ages of high school youth who face homelessness in the state, their health risks, and use of support services in the last 12 months using data from the Michigan Department of Education, Michigan's 2018 Annual Report on Ending Homelessness, and the 2019 Youth Risk Behavior Survey (YRBS). Based on this analysis it was found that the likely number of homeless unaccompanied minors in Michigan is much higher than shelter or school data suggest. Data also show that homeless youth in Michigan face much higher risks to their health and well-being and are accessing primary health care at much lower rates than their housed peers.
