The purpose of the Behavioral Risk Factor Surveillance System (BRFSS) survey is to obtain estimates of the prevalence of personal health behaviors that contribute to morbidity and mortality. The BRFSS county-level survey was conducted among adults in Florida in 2002, 2007, 2010, 2013 and 2016. Starting in 2017, the Florida Department of Health began using a three-year rolling rate methodology to provide annual county-level data. Rolling rates are calculated by combining data across several consecutive years into one measure. Survey completes from each of the 67 counties were combined across the 2017-2019 survey period in order to produce statistically valid county-level estimates. This methodology was designed in collaboration with the county health departments (CHDs) to better meet programmatic needs for local-level data.

NOTE: Caution should be taken when comparing data from 2013 with previous years due to changes in survey methodology.
