Dataset Summary
The Behavioral Risk Factor Surveillance System (BRFSS) is a large, state-based telephone survey that collects data on health-related behaviors, chronic conditions, preventive services, and social determinants among U.S. adults. It is commonly used for population health surveillance, state- and local-level analyses, and to examine geographic variation in health behaviors and outcomes.
Caveats

- Complex survey design requires appropriate weighting for valid inference
- Not all states include optional modules in every year
Examples of Outcomes Examined
- Health behaviors (e.g., smoking, physical activity)
- Chronic disease prevalence
- Preventive service utilization
