Data Sources That Enumerate People Experiencing Homelessness in the United States: Opportunities and Challenges for Epidemiological Research.

Homelessness is associated with a multitude of poor health outcomes. However, the full extent of the risks associated with homelessness are not possible to quantify without reliable population data. Here, we outline three federal, publicly-available data sources available to estimate the number of people experiencing homelessness in the United States. We describe the appropriate uses and limitations of each data source in the context of infectious disease epidemiology. These data sources provide an opportunity to expand current research and develop actionable analyses.
