SURVEILLANCE - Source of the Maps:

The data shown in these maps were collected through CDCs Behavioral Risk Factor Surveillance System (BRFSS). Each year, state health departments use standard procedures to collect data through a series of telephone interviews with U.S. adults. Height and weight data are self-reported.
