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 homeless people on a single night in January. Although not required by HUD, Allegheny County has also conducted 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 2017, including the number of individuals and families who were experiencing homelessness, their demographics, and the types of shelters where they were staying.
