Years of Data Used
Comprehensive Housing Affordability Strategy (CHAS) data
The U.S. Department of Housing and Urban Development (HUD) periodically receives "custom tabulations" of data from the U.S. Census Bureau that are largely not available through standard Census products. These data, known as the "CHAS" data (Comprehensive Housing Affordability Strategy), demonstrate the extent of housing problems and housing needs, particularly for low income households. The CHAS data are used by local governments to plan how to spend HUD funds, and may also be used by HUD to distribute grant funds.
While our exact measure cannot be stratified, there are options available for the underlying measures. Overcrowding by race can be calculated from tables B25014A-I. Lack of complete plumbing or kitchen facilities, housing costs as a percentage of income, and overcrowding can be calculated for census tracts and census block groups using table DP04. These tables can be accessed through the American Factfinder. In addition, the Community Commons Health Equity Assessment Report provides a census tract map of the rate of substandard housing.
