In this Focus on Families with Children brief, the United States Interagency Council on Homelessness (USICH) reviews data and information on the following: the scale of family homelessness; knowledge about the families with children who experience homelessness; knowledge about patterns of homelessness among families with children; knowledge about families’ risks for experiencing homelessness; and the most significant gaps in available data and current understanding of families with children who experience homelessness. This brief is apart of USICH's Homelessness in America series, which aims to build upon a clear understanding of who is at risk of homelessness, who experiences homelessness, and differences within and between subpopulations of people who are at risk or are experiencing homelessness.
