BRFSS 2012 Survey Data and Documentation
On this Page
The 2012 BRFSS data continues to reflect the changes initially made in 2011 in weighting methodology (raking) and the addition of cell phone only respondents. The aggregate BRFSS combined landline and cell phone dataset is built from the landline and cell phone data submitted for 2012 and includes data for 50 states, the District of Columbia Guam, and Puerto Rico.

Comparability of Data
Comparability of data across reporting areas for the combined landline and cell phone data set. The BRFSS 2012 data is not directly comparable to years of BRFSS data before 2011 because of the changes in weighting methodology and the addition of the cell phone sampling frame.
