2The BRFSS has adopted new weighting procedures in order to accommodate the inclusion of new variables, including the type of phones owned by respondents. Details are provided in the June 8, 2012 issue of the Morbidity and Mortality Weekly Report (MMWR), which highlights weighting effects on trend lines (www.cdc.gov/mmwr/preview/mmwrhtml/mm6122a3.htm).

3The AAPOR Cooperation Rate #2 is the number of complete and partial complete interviews divided by the number of interviews (complete plus partial) plus the number of non-interviews that involve the identification of and contact with an eligible respondent (refusal and break-offs plus other) (http://www.aapor.org/Standard_Definitions2.htm).

4The AAPOR Response Rate Formula #4 is the number of respondents who completed the survey as a proportion of all eligible and likely-eligible persons (http://www.aapor.org/Standard_Definitions2.htm).
