National Data Sources

CHSI 2015 is an interactive web application that produces health profiles for all 3,143 counties or county equivalents in the United States. Each profile includes key indicators of health outcomes, which describe both the population health status of a county and some factors that have the potential to influence health outcomes, such as health care access and quality, health behaviors, social factors and the physical environment.

Community Commons is an interactive mapping, networking, and learning utility for the broad-based healthy, sustainable, and livable communities’ movement. Registered users have FREE access to:

  • Over 7000 GIS data layers at state, county, zip code, block group, tract, and point-levels.
  • Contextualized mapping, visualization, analytic, impact and communication tools and apps.
  • Searchable profiles of hundreds of place-based community initiatives (multi-sector collaboratives) working towards healthy/sustainable/livable/equitable communities - funded by government and private philanthropy - complete with text & video narratives on "what's working."
  • Peer learning forums in the "interactive commons" with colleagues exploring similar interests and challenges - hosted by leading national Technical Assistance providers.

The Rural Assistance Center has compiled an extensive list of resources and tools relevant to exploring health in smaller geographic areas of the nation. Many of the data sources used in the County Health Rankings can be found here, as well as a plethora of others.
