The Robert Wood Johnson Foundation and the University of Wisconsin's Population Health Institute have released "County Health Rankings: Mobilizing Action Toward Community Health," a health report card for almost every one of the nation's more than 3,000 counties. For the report, researchers combined federal and state health-related data on 3,016 counties in the U.S. The information was then analyzed by researchers who have been conducting similar reports for the state of Wisconsin for six years, USA Today reports.
