Each year, Allegheny County participates in a national effort required by the U.S. Department of Housing and Urban Development (HUD) to count the number of people who were homeless on a single night in January. Although not required by HUD, Allegheny County also conducts a summer point-in-time (PIT) count to better understand warm weather trends. This data brief provides information about the PIT counts conducted in January and July 2018, including the number of individuals and families who were experiencing homelessness, their demographics, and the types of shelters where they were staying.
