Why Is This Important?

Data Notes


In 2011, the BRFSS changed its methodology from a landline only sample and weighting based on post-stratification to a landline/cell phone sample and raking as the weighting methodology. The 2011-2012 data on this graph is based on the new methodology (landline/cell phone sample; raking). Due to changes in both sampling and the question format, 2011-2012 data should be interpreted with caution compared to previous years.

These rates are crude rates, not age-adjusted, given that the Healthy People 2020 Objective is based on crude rates.
