2011 Landline Questionnaire Data Sets

In 2011 the BRFSS consisted of two survey modes, landline and cell phone. Several states collected optional modules on the landline survey only. The optional modules and state-added questions must be asked throughout all twelve months of the survey. An additional data set containing the optional module data and weights are provided for use with variables resulting from questions asked only on the landline version of the questionnaire.

To reduce confusion about which weight to use with which variable, the additional landline data set is available for 2011. For more information, please refer to the documentation below.
