Screening and Risk Factors Table

How do you find them?
These estimates are only available for
- Mammogram in Past 2 Years, Ages 40+
- Mammogram in Past 2 Years, Ages 50-75
- Pap Smear in Past 3 Years, No Hysterectomy, Ages 18+
- Had Colonoscopy in Past 10 Years, Ages 50-75
- Guidance Sufficient CRC, Ages 50-75
- Fecal occult blood test (FOBT), Ages 50-75
- Smokers (current), Age 18+
- Percent of Daily Smokers Who Stopped Smoking for 1 day or Longer in the Past 12 Months, Age 18+
- Former Smoking Prevalence, Age 18+
- Former Smoking Prevalence who Quit 1 Year, Age 18+
- Percent of Workers in Non-Smoking Environments (All People)
Select one of those statistics in the Screening and Risk Factors drop-down, and then you can choose County-Level Modeled Estimates in the Data Type drop-down when you choose Counties for a specific state (e.g., Alabama Counties) in the Area drop-down.
For more about what these estimates are, see the Data Type Explanation.

Why are they different?
One difference is that the direct estimate is from data collected in one year, while the modeled estimate relies on pooled data from 2017 through 2019 or 2018 through 2019.
Another difference is that the modeled estimates use data from BRFSS as well as another survey (NHIS) that has a smaller but more representative sample, in that NHIS includes people without phones or with only cell phones. The national cancer screening prevalence estimates based on the BRFSS was sometimes substantially larger than the NHIS estimates for the same time period. For similar time periods, the modeled estimates may be closer to the true value.
See the Data Type Explanation.
The model uses multiple years (2008-2010) to provide reasonable sample sizes (mainly for estimates at the county level), and needs at least two years of data from each survey. For the screening questions, data actually came from year 2008 and 2010. For smoking, data came from each year of 2008 to 2010.

2 2023 BRFSS Survey Data is the source for this data collected by the Behavioral Risk Factor Surveillance System (BRFSS) sponsored by the Centers for Disease Control and Prevention. Data for the US is a median and not a percent.
BRFSS Prevalence estimates presented here may vary from other published estimates due to differences in the methodology used to generate estimates.
Data for United States does not include Puerto Rico.
