  In the 2011 Kansas BRFSS, all Core Section questions & State-Added Module on Average Hours Worked were asked of both the Kansas BRFSS Land line and Kansas BRFSS Cell Phone survey respondents. All Kansas CDC Optional Modules and Kansas State-Added Modules (except for State-Added Average Hours Worked Module), this includes all Version A and Version B questions, were asked ONLY of the Kansas BRFSS Land line survey respondents.

The new survey methodology, including dual frame sampling and the iterative proportional fitting (IPF) or raking method, was used for the 2011 data. Therefore, DO NOT COMPARE 2011 data with previous years.
