The Robert Wood Johnson Foundation and the University of Wisconsin Population Health Institute in Madison released their 2023 County Health Rankings, which examine health outcomes and more than 90 health factors at the county level.
For the rankings, the organizations use county-level data collected between 2014 and 2022 to evaluate the health outcomes and factors of nearly all U.S. counties within states.
Below is a list of the counties with the lowest-ranked health outcomes in each state. The overall health outcomes rank is weighted 50 percent by length of life and 50 percent by quality of life, each of which contains individual measures, such as premature death, low birthweight, life expectancy, and frequency of physical and mental distress.
Comprehensive county health rankings data is available here. Find rankings per state, county or ZIP Code here. Methodology details are available here. Find the listing of last year's healthiest counties per state here for comparison.
