The annual County Health Rankings measure vital health factors, including high school graduation rates, obesity, smoking, unemployment, access to healthy foods, the quality of air and water, income inequality, and teen births in nearly every county in America. The annual Rankings provide a revealing snapshot of how health is influenced by where we live, learn, work and play. They provide a starting point for change in communities. That is why researchers also provide the Roadmaps that provide guidance and tools to understand the data, and strategies that communities can use to move into action. The Roadmaps are helping communities bring people together from all walks of life to look at the many factors that influence health, focus on strategies that we know work, learn from each other, and make changes that will have a lasting impact on health.
