Each record includes crude and age-adjusted prevalence estimates together with their corresponding 95% confidence intervals.
Available data include:
- County and state
- County FIPS code
- Crude obesity prevalence
- Crude 95% confidence interval
- Age-adjusted obesity prevalence
- Age-adjusted 95% confidence interval
