Area Deprivation Index (ADI)

The Area Deprivation Index (ADI) is based on a measure created by the Health Resources & Services Administration (HRSA) over two decades ago for primarily county-level use, but refined, adapted, and validated to the Census block group/neighborhood level. It allows for rankings of neighborhoods by socioeconomic disadvantage in a region of interest (e.g. at the state or national level). It includes factors for the theoretical domains of income, education, employment, and housing quality. It can be used to inform health delivery and policy, especially for the most disadvantaged neighborhood groups.

Estimation Technique

The Area Deprivation Index (ADI) estimates the average level of deprivation in an area by combining different indicators of socioeconomic disadvantage. The index is used to identify areas with high levels of deprivation so that resources can be targeted to those areas. The ADI is based on several socioeconomic indicators, including income, education, employment, housing, and transportation. These indicators are combined into a single index using a statistical technique called factor analysis. The ADI is calculated for small geographic areas, such as census tracts or zip codes. It can also be calculated for larger geographic areas, such as counties or states.
