Crude prevalence is the estimated share of all adults. CDC: "We don't provide age-adjusted prevalence estimates at census tract and ZCTA levels because some of these areas do not have population in all age groups used in the adjustment process."

Estimates by release
What each PLACES release published for ZIP 35221 (crude prevalence with 95% interval). CDC advises that the estimates cannot be used to track local change over time: each release re-models a different survey year onto a fixed population, intervals usually overlap and the interval method changed in 2023. Listed for reference only. The 2022 and 2023 columns use 2010-vintage Census geographies for ZIP Codes and places (the same code may have covered a different area); 2024 onward use 2020 geographies.

Questions and answers
What share of adults in ZIP Code 35221 have obesity, according to PLACES?
PLACES estimates 46.7% (95% confidence interval 41.8–51.7%) in the 2025 release, based on 2023 BRFSS responses modelled onto the area's adult population. It is a modelled estimate for the whole adult population of the area, not a count of diagnoses.
How common is diagnosed diabetes in ZIP Code 35221?
PLACES estimates 25.8% of adults (95% confidence interval 23.2–28.5%) in the 2025 release. The national estimate in the same release is 12.0%.
Is ZIP Code 35221 different from Jefferson County on obesity?
The 95% confidence intervals for ZIP Code 35221 and Jefferson County overlap for obesity, so the estimates are described as similar; the model cannot separate them.
Can these figures describe a person who lives in ZIP Code 35221?
No. CDC states: "We do not produce estimates for individuals; only aggregated results for counties, places, census tracts, or ZCTAs." The figures describe the expected prevalence across the area's adult population given its demographic make-up and its county and state; they say nothing about any resident.
Can ZIP Code 35221 be ranked or tracked over time with these figures?
CDC advises that the data "should not be used for ranking the overall health of any county, place, census tract, or ZCTA" and that the modelling procedure "does not support using the estimates to track changes at the local level over time". Areas can be compared on individual measures, with their confidence intervals; this site lists estimates by release for reference only.
