Behavioral Risk Factor Surveillance System: Information for Researchers and Data Users
Data resources and documentation
Wisconsin Behavioral Risk Factor Surveillance System (BRFSS) data can be accessed by the Department of Health Services (DHS) and CDC (Centers for Disease Control and Prevention) data portals and query systems. See the “Reports and Products” page for links. CDC also releases national datasets each year on their BRFSS webpage.
Note that the CDC national data set does not include data at a geographical level more specific than the state (for example, county level) or questions that are unique to Wisconsin and not required by CDC (for example, prescription pain medication module).
