MMWR: Surveillance for Certain Health Behaviors Among States and Selected Local Areas — Behavioral Risk Factor Surveillance System, United States, 2011, Surveillance Summaries / Vol. 63 / No. 9, Oct 24, 2014

The Behavioral Risk Factor Surveillance System (BRFSS) is an ongoing, state-based, random digit-dialed telephone survey of non-institutionalized adults aged ≥18 years residing in the United States. BRFSS collects data on health-risk behaviors, chronic diseases and conditions, access to health care, and use of preventive health services and practices related to the leading causes of death and disabilities in the United States. In 2011, BRFSS adopted a new weighting methodology (iterative proportional fitting, or raking) and included data from respondents using cellular telephones only. This report presents results for the year 2011 for all 50 states, the District of Columbia, and participating U.S. territories including the Commonwealth of Puerto Rico and Guam, 198 MMSAs, and 224 counties.
