Using America’s Health Rankings, University of Wisconsin Population Health Institute is providing every year since 2010, for nearly every county in US health ranking data.
The counties health rankings are based on counties and county equivalents (ranked places). Any entity that has its own FIPS county code was included in the rankings. Are included only counties and county equivalents within a state. The major goal of the Rankings is to raise awareness about the many factors that influence health and that health varies from place to place. Counties in each of the 50 states are ranked according to summaries of a variety of health measures. Those having high ranks, e.g. 1 or 2, are considered to be the “healthiest.” Counties are ranked relative to the health of other counties in the same state. Most of the data used were public data available at no charge. Measures based on vital statistics data, sexually transmitted disease rates and Behavioral Risk Factor Surveillance System (BRFSS) survey data were calculated for this project by staff at the National Center for Health Statistics and other units of the Centers for Disease Control and Prevention (CDC). The healthcare quality measures included were calculated by the authors of the Dartmouth Atlas of Healthcare, using Medicare claims data. In many ranked counties, some individual measures do not have a large enough sample size to report data for that measure. In these counties, the state average was assigned for any missing measure in order to calculate a rank for that category.
Top performers refer to the value for which only 10% of counties in the country are doing better, i.e., the 90th percentile or 10th percentile, depending on whether the measure is framed positively (e.g., high school graduation) or negatively (e.g., adult smoking).
