National Neighborhood Data Archive: Standardized Area Deprivation Index (ADI) by Census Block Group, United States, 2015, 2020 and 2022

This dataset recreates three releases (2015, 2020, and 2022) of The Neighborhood Atlas team’s Area Deprivation Index (ADI) using standardized components. The ADI is a measure that aims to quantify the socioeconomic conditions of census block groups (sometimes used to approximate neighborhoods), originally based on 1990 census tract data and factor loadings. The Neighborhood Atlas team at the University of Wisconsin adapted the ADI to block groups and more recent data, imputing missing data using tract- and county-level data.<br><br>However, unlike the original index construction method, The Neighborhood Atlas team did not adjust (standardize) individual components before combining them into an overall score. This approach resulted in individual index components measured in dollars, such as income and home value, being overly influential in the final score. This dataset corrects for that by standardizing these components before aggregating, offering a more multi-dimensional view of socioeconomic conditions. The standardized ADI dataset provides continuous rankings for block groups nationwide and decile rankings for block groups within each state.
