The Behavioral Risk Factor Surveillance System (BRFSS) measures the prevalence of health related behaviors among adults. In Florida, the survey is conducted at both the state and county levels, with county surveys completed in 2002, 2007, 2010, 2013, and 2016. Beginning with the 2017–2019 cycle, the Florida Department of Health piloted a three year rolling rate method that combines multiple consecutive years of data to improve the reliability of county level estimates. This process is ongoing, and while rolling rates enhance local-level data, they do not yet produce annual county estimates. The BRFSS targets Florida residents aged 18 and older living in households.

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