CRC Test Ever Maps and Data of Model-Based Small Area Estimates
Definition (prior to 2011):
For the ever had colorectal cancer test, a person 50 years of age or older must have reported having at least one colorectal endoscopy (sigmoidoscopy or colonoscopy) in his/her life or at least one home-based FOBT within the past two years by the time of interview.
For the data periods 2004-2010, the colorectal cancer test questions were asked in BRFSS in the even years as part of the core questionnaire for all states, and in NHIS in 2005, 2008, and 2010. The questions were worded in similar ways on the two surveys, except that for the time since most recent home-based FOBT test question, NHIS asked for exact year, date or time period while BRFSS only asked for time period.
CRC Test Ever estimates are no longer produced for 2011 and forward because definition changes due to updated U.S. Preventive Services Task Force (USPSTF) recommendations on colorectal cancer screening. Estimates for Guidance Sufficient CRC are released instead.
Available estimates are for the time periods 2004-2007 and 2008-2010, and on maps and in data tables by county (except counties in Alaska), health service area (HSA) and state. Click on the map to view data values and confidence intervals for individual regions.
