Area Deprivation Index by Census Block Group

| 0

The 2023 Area Deprivation Index is now available! The ADI map displays rankings of neighborhoods by socioeconomic status 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. The 2023 ADI was constructed using the 2019-2023 5-year estimates from the US Census’ American Community Survey.
