  • NOTE: SAE, small area estimates.

  • Any colorectal cancer test type = home FOBT within the past year; sigmoidoscopy within 5 years with FOBT within 3 years; or colonoscopy within 10 years. We used a modified Monte Carlo simulation method for estimating the model-based predicted standard errors.

  • aAIAN = American Indian/Alaska Native.

  • bNH other = Pacific Islander (PI), other one race, and 2 or more races.

  • An additional analysis comparing mean estimates of counties with ≥500 respondents shows that the mean abs difference between the model-based estimates and the BRFSS direct estimates for being current with any colorectal cancer test type is 2.3, SE = 0.127 and interquartile range = 2.43.
