The BRFSS is a unique, state-based surveillance system active in all 50 states, the District of Columbia, Puerto Rico, and Guam. Reaching participants on both landline and cellular telephones, the survey collects information on health risk behaviors, clinical preventive health practices, and health care access (primarily related to chronic disease and injury) from a representative sample of noninstitutionalized adults aged 18 years or older in each state. The BRFSS provides flexible, timely, and ongoing data collection that allows for state-to-state and state-to-nation comparisons. State-specific data—including racial- and ethnic-specific data from the BRFSS—provide a sound basis for developing and evaluating public health programs, including programs targeted to reduce racial and ethnic disparities in addressing health risks.
The BRFSS is the largest ongoing telephone-based health surveillance system in the world, with more than 435,000 interviews conducted in 2018. BRFSS staff are working to make this new data set available soon through its online Prevalence and Trends Tools.
