Key Findings

1. A Los Angeles County program provides supportive housing coupled with case management to those experiencing homelessness and was associated with sharp reductions in health care use by program participants.
2. Across all the public services examined, the cost of services for participants declined by nearly 60 percent during their first year in the program.
3. Participants' self-reported mental health functioning improved after receiving housing, though self-reported physical health was largely unchanged.

On any given night, more than 553,000 people — a number greater than the population of Tucson, Arizona — experience homelessness in the United States. The problem is especially acute in California, where approximately 24 percent of those experiencing homelessness live, and in Los Angeles County, which has more unsheltered homeless individuals than any other U.S. city or county. Based on 2017 data, on an average night in Los Angeles County, an estimated 55,000 people are homeless — almost 10 percent of the national total of individuals experiencing homelessness (see Figure 1).
