The 2011 survey marks the first year in which the Pennsylvania BRFSS collected data from both landline and cell phone respondents. To allow for the incorporation of cell phone data, a new weighting methodology called iterative proportional fitting or raking was implemented in 2011. A detailed explanation of raking can be referenced in our Changes in the BRFSS Methodology document. These methodological changes will cause breaks in BRFSS trends, but they will also significantly improve the accuracy, coverage, validity, and representativeness of the Pennsylvania BRFSS. Therefore, measures should be re-benchmarked at the 2011 estimate values, and not compared to BRFSS estimates from previous years.
The BRFSS reports can be found below:
Past and present BRFSS questionnaires can be found below:
BRFSS data for 2011 and prior years can be found through the Pennsylvania Department of Health's Epidemiologic Query and Mapping System (EpiQMS). In addition to single year data as seen in the annual report, you will have access to three-year aggregate statewide and regional data, including county and county aggregate BRFSS statistics.
