RWJF Culture of Health Prize

The RWJF Culture of Health Prize honors and elevates U.S. communities that are making great strides in their journey toward better health.

Our Approach

The Rankings are based on a model of population health that emphasizes the many factors that, if improved, can help make communities healthier places to live, learn, work and play. Building on the work of America's Health Rankings, the University of Wisconsin Population Health Institute has used this model to rank the health of Wisconsin’s counties every year since 2003.

Rankings Methods

The County Health Rankings measure the health of nearly all counties in the nation and rank them within states.  The Rankings are compiled using county-level measures from a variety of national and state data sources. These measures are standardized and combined using scientifically-informed weights.
