Area Deprivation Index (ADI) for US Census Block Groups, 2015, 2020, and 2023 (CSV)

This dataset contains year-specific Area Deprivation Index (ADI) extracts for US Census Block Groups for 2015, 2020, and 2023, prepared for downstream spatial exposure linkage workflows. Each CSV includes the following fields:DATA_YEAR, GISJOIN, FIPS, TRACTFIPS, BLOCK_GROUP, ADI_NATRANK, ADI_STATERNK Processing notes:FIPS is normalized to a 12-digit block-group identifier.TRACTFIPS is derived from the first 11 digits of FIPS.ADI_NATRANK and ADI_STATERNK are stored as numeric fields.Source suppression codes that are non-numeric are represented as empty values in numeric output columns.
