Area Deprivation Index (ADI)

The Area Deprivation Index (ADI), developed by the University of Wisconsin, is a composite measure of socioeconomic status. It incorporates variables such as income, education, employment, and housing quality. The ADI is calculated for each census tract in the United States and grouped into deciles—lower deciles indicate more affluent areas. ADI provides both nationwide and state-ranked scores.
