The County Health Rankings show us that where we live matters to our health. The health of a community depends on many different factors – ranging from individual health behaviors, education and jobs, to quality of health care, to the environment. This collection of 50 reports – one per state – helps community leaders see that where we live, learn, work, and play influences how healthy we are and how long we live. The Robert Wood Johnson Foundation is collaborating with the University of Wisconsin Population Health Institute to develop these Rankings for each state’s counties.
