2019 BRFSS Survey Data and Documentation

The 2019 BRFSS data continue to reflect the changes initially made in 2011 for weighting methodology (raking) and adding cell-phone-only respondents. The aggregate BRFSS combined landline and cell phone data set is built from the landline and cell phone data submitted for 2019 and includes data for 49 states, the District of Columbia, Guam, and Puerto Rico.
