Missed Opportunities: Counting Youth Experiencing Homelessness in America summarizes key lessons learned from conducting point-in-time counts of youth experiencing homelessness in 22 diverse counties across the United States. Youth counts can provide communities with valuable information about the number and characteristics of youth experiencing homelessness, including information about over-represented groups for whom specialized services might be needed. Additionally, by conducting annual or biennial youth counts, communities can identify changes over time in the local population of youth experiencing homelessness. This brief offers recommendations for conducting successful youth counts based on our experiences conducting counts and insights shared by our partner counties. We hope these recommendations will help more communities conduct youth counts that yield valuable data and drive positive change.
