How does it work?

The 2025 Health Equity Index (formerly SocioNeeds Index), created by Conduent Healthy Communities Institute, is a measure of socioeconomic need that is correlated with poor health outcomes. The index is part of Conduent's SocioNeeds Index® Suite, which provides analytics around social determinants of health to advance equitable outcomes for a range of topics.

All zip codes, counties, and county equivalents in the United States are given an index value from 0 (low need) to 100 (high need). To help you find the areas of highest need in your community, the selected locations are ranked from 1 (low need) to 5 (high need) based on their index value relative to similar locations within the region.
