Socioeconomic Position Indices (SEPI)

Main content start

Reproducible area deprivation measures for research and policy

Socioeconomic Position Indices (SEPIs) are powerful tools for identifying areas of social vulnerability and guiding the equitable allocation of resources. When used effectively, they help target interventions, reduce health and social disparities, and ensure that funding reaches the communities that need it most.

While many indices have been developed across the U.S. and globally, they are often scattered, inconsistently documented, or difficult to reproduce. This site was created to address that gap, offering a centralized, accessible, and transparent resource for researchers, policymakers, and practitioners working to advance equity through data-driven decision-making.

Estimation of Mortality via the Neighborhood Atlas and Reproducible Area Deprivation Indices

New Publication

This cross-sectional study introduces the Reproducible Area Deprivation Index (ReADI) as a corrected, transparent replacement for the Neighborhood Atlas ADI (NA-ADI) and evaluates how calculation errors (notably failure to standardize inputs) contribute to systematic score differences. Across block group, tract, and county geographies, ReADI aligns more closely with other established deprivation indices and better reflects intended component weighting than NA-ADI. In high-discrepancy census tracts, ReADI also improves estimation of mortality/life expectancy associations, supporting its use for health equity research and policy applications where measurement errors can misallocate resources.
