The 2011 BRFSS data reflects a change 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 2011 and includes data for 50 states, the District of Columbia and Puerto Rico. There are two territories (Guam, Virgin Islands) which are not included in the initial data release because current population estimates are not available at this time. These territories will be included after the 2010 Census estimates have been released. Please note the data set naming convention and weighting variables have changed. More information about the changes to the 2011 BRFSS is available, http://www.cdc.gov/surveillancepractice/reports/brfss/brfss.html.

compare_11.rtfComparability of data across reporting areas for the combined landline and cell phone data set. The BRFSS 2011 data should be considered a baseline year for data analysis and is not directly comparable to previous years of BRFSS data because of the changes in weighting methodology and the addition of the cell phone sampling frame.
