The Robert Wood Johnson Foundation (RWJF) in collaboration with the University of Wisconsin Population Health Institute (UWPHI) released its 2015 County Health Rankings & Roadmaps. Now in its sixth year, the County Health Rankings measures the overall health of each county in all 50 states on the many factors that influence health. The Rankings are compiled using county-level measures from a variety of national data sources. These measures are standardized and combined using scientifically-informed weights. Counties are then ranked within each state, providing two overall ranks:
1. Health outcomes: how healthy is a county now?
2. Health factors: how healthy will a county be in the future?
These ranks are reported at countyhealthrankings.org, along with all the underlying measures for this year and prior years. Tools are also provided to help communities use their data to identify opportunities for improvement and guidance to help them take action toward improving their health.
