Healthy Communities Data and Indicators Project​​

The Healthy Communities Data and Indicators Project (HCI) provides a standardized set of statistical measures, data, and tools on the social determinants of health in California. The goal of the HCI is to provide datasets and tools that a broad array of sectors can use for planning healthy communities and evaluating the impact of plans, projects, policy, and environmental changes on community health.

Indicator datasets include data for California, as well as its counties, regions, communities, and census tracts when available. Datasets also include stratifications by race/ethnicity and other population characteristics. Indicators are organized by the "A-N" categories in Section 131019.5 of the California Health and Safety Code (PDF). Content for these indicators is updated as data becomes available.  The majority of datasets here can also be found on the California Health and Human Services Open Data Portal. For any questions, please contact

Find out more information on the background of HCI (PDF).
