Homeless youth are greatly undercounted in the United States. Census methods for homeless adults are inappropriate for homeless youth; thus, nationally, organizations are determining new methods for counting homeless youth. In collaboration with the Hollywood Homeless Youth Partnership, we utilized an agency-based approach to count and survey all homeless youth entering their facilities and encountered on their outreach activities. Between October 19 and October 25, 2012, 460 unique homeless youth were counted and surveyed in Hollywood. Of these, 222 experienced literal homelessness on the night of Thursday, October 18, 2012, and 381 experienced literal homelessness within the previous year. Literal homelessness refers to youth who are either living in emergency or transitional housing or living on the streets or in parks, abandoned buildings, cars, subway tunnels, or other places not meant for human habitation. Of the surveyed youth who experienced literal homelessness in the last year, 65% were male, their average age was 21 years, their average age of first literal homelessness experience was17 years, and 43% were from Los Angeles. Our week-long, agency-based approached was successful in enumerating homeless youth in Hollywood.
