ABOUT THIS DATASET
Overview
The Behavioral Risk Factor Surveillance System (BRFSS) Prevalence Data, collected by the Centers for Disease Control and Prevention (CDC) and the U.S. Department of Health & Human Services, provides state-based prevalence data on modifiable risk factors for chronic diseases and other leading causes of death. This dataset, spanning from 2011 to the present, includes combined landline and cell phone survey responses, offering continuous surveillance information. Each record represents aggregated prevalence statistics for a specific health-related question, broken out by demographic characteristics or other categories, for a given year and state.

GOOD TO KNOW
Before you start
Practical notes on the structure and quirks of this dataset, from Mira’s profile.
Aggregated prevalence estimates, not individual survey responses.
About 20% of rows have no estimate, usually because the sample was too small to report.
