To prevent and end homelessness in America, we need to have a clear understanding of who is at risk of homelessness and who experiences homelessness. We also need to be attentive to differences within and between subpopulations of people who are at risk for or are experiencing homelessness. The USICH Homelessness in America series summarizes the most relevant data and research regarding different subpopulations to help inform the work which must take place, together, across the federal government, states, and local communities to end homelessness once and for all.

The brief focused on individuals who experience homelessness as adults without children. This population includes people who also fall into other population categories, such as Veterans, people experiencing chronic homelessness, and unaccompanied youth 18 years old or older. In most cases, the available data does not make it possible to differentiate among these populations. Other briefs in this series focus separately on Veterans, people experiencing chronic homelessness, unaccompanied youth, and families with children.
