This Research-to-Impact brief is the first in a series by Chapin Hall's Voices of Youth Count on understanding and addressing youth homelessness. "Missed Opportunities: National Estimates" highlights results from a national survey on unaccompanied youth homelessness in America. The study captures youth homelessness broadly, including sleeping on the streets, in shelters, running away, being kicked out, and couch surfing. Overall, findings show one in 10 young adults ages 18-25, and at least one in 30 adolescents ages 13-17, experience some form of homelessness unaccompanied by a parent or guardian over the course of a year. As a nation, we are missing opportunities to ensure that all young people can reach their full potential and contribute to stronger communities and economies across the country.
