The Behavioral Risk Factor Surveillance System (BRFSS) is a collaboration between the U.S. Centers for Disease Control and Prevention (CDC) and state health departments. This system was designed to gather locally relevant information on health related behaviors related to the leading causes of death in the US. It has expanded to include data on the prevalence of selected health conditions, and access to health services. Each state has options for sample design and data collection within parameters set by CDC.

In Illinois, the state is stratified into 5 regions: Chicago, Surburban Cook County, Collar Counties, other Urban Counties, and Rural Counties.
