A collaboration between the Robert Wood Johnson Foundation and University of Wisconsin Population Health Institute, this website ranks the overall health of each county in the United States and highlights the impact of social factors such as poverty on health outcomes. Utilizing a variety of indicators, including the rate of people dying before age 75, high school graduation rates, unemployment, limited access to healthy foods, air and water quality, income, rates of smoking, obesity and teen births, these rankings offer a useful starting point for understanding the many determinants that influence the health of our communities.
