HUD’s Office of Policy Development & Research has released the latest Comprehensive Housing Affordability Strategy (CHAS) data. The data demonstrates the extent of housing needs throughout the nation, particularly for low-income households, and is used by local governments to plan how to allocate HUD funds. The CHAS data are derived from U.S. Census Bureau data and are available for download through the HUD USER website. HUD releases updated CHAS datasets as they are obtained.
