The Robert Wood Johnson Foundation and the University of Wisconsin Population Health Institute in Madison released their 2020 County Health Rankings March 18.
For the rankings, the organizations use county-level data to rank the health of nearly all U.S. counties within states. Researchers use more than 30 measures across four areas — health behaviors, clinical care, physical environment, and social and environmental factors — to develop the rankings.
Below is a list of the county with the worst health outcomes in each state. Access state-specific data here. To see a list of the healthiest county in each state, click here.
