For the colonoscopy within the past 10 years, a person aged 50-75 must have reported having at least one colonoscopy within the past 10 years at the time of interview.
For the data periods 2011-2023, the colorectal colonoscopy questions were asked in BRFSS in the even years as part of the core questionnaire for all states, and in NHIS in 2013, 2015, 2018, 2019, 2021, and 2023. The questions were worded in similar ways on the two surveys.
Available estimates are for the time periods 2011-2016, 2017-2019, and 2021-2023, and on maps and in data tables by county, health service area (HSA) and state. The county estimates (2017-2019) are also released in State Cancer Profiles. Click on the map to view data values and confidence intervals for individual regions.
