The Behavioral Risk Factor Surveillance System (BRFSS) is a national random digit dial (RDD) telephone survey. Data obtained from the BRFSS are representative of the total non-institutionalized population over 18 years of age living in households with a land line telephone. For the County Health Rankings, data from the BRFSS are used to measure various health behaviors and health-related quality of life (HRQoL) indicators. All data from the BRFSS are weighted by population and the HRQoL measures are age-adjusted. We obtained county-level measures, in almost all instances aggregated over seven years, from the National Center for Health Statistics (NCHS)/Centers for Disease Control and Prevention (CDC).

Example Indicators
