This research brief from SchoolHouse Connection looks at demographic and risk factor data of high school students experiencing homelessness compared with students not experiencing homelessness. It uses the Youth Risk Behavior Survey (YRBS) results from 17 states during the 2016-2017 school year. The survey breaks down where students reported sleeping during the past 30 days. SchoolHouse Connections analyzed these data to determine the vulnerability of youth in different homeless living situations to health risk behaviors. Across the different categories, students were vulnerable to violence, suicide, substance abuse, hunger, bullying, and sleep deprivation. This brief provides action steps and additional resources for schools. (author abstract modified)
