Diagnosed diabetes among adults
Health outcomes. Survey year (BRFSS) of the 2025 release: 2023. CDC published this measure in the 2022, 2023, 2024, 2025 releases.
The figures are model-based estimates for the adults of an area. They are not measurements. They say nothing about one person.
We do not produce estimates for individuals; only aggregated results for counties, places, census tracts, or ZCTAs.
First, it is not adequate to simply compare point estimates. The confidence intervals should also be considered, and some are very broad.

What CDC measures
A multi-level regression and post-stratification approach was applied to BRFSS and ACS data to compute a detailed probability among adults who report being told by a doctor or other health professional that they have diabetes (other than diabetes during pregnancy for female respondents). The probability was then applied to the detailed population estimates at the appropriate geographic level to generate the prevalence. The 95% confidence interval was derived using Monte Carlo simulation.
Population: All Adults.
Nearly one-fourth of U.S. adults with diabetes are undiagnosed. As self-awareness of having diabetes is low, the prevalence of diabetes may be underestimated.

BRFSS is the Behavioral Risk Factor Surveillance System, the telephone survey that the model uses. The glossary has the terms.

|---|---|---|---|
| United States, crude | 12.0% | 11.8 to 12.2 | |
| United States, age-adjusted | 10.3% | 10.1 to 10.5 |

County estimates in the United States
The drawing shows the crude estimates of 2,956 counties in 24 equal steps. It names no county. A county with no estimate in the PLACES 2025 release is not in the drawing.
- A tenth of the county estimates are below 10.4%.
- A quarter of the county estimates are below 11.8%.
- Half of the county estimates are below 13.3%. This is the median.
- A quarter of the county estimates are above 15.2%.
- A tenth of the county estimates are above 17.3%.
By state
Crude prevalence is the estimated share of all adults. Age-adjusted prevalence uses the 2000 US standard population, so that areas with different ages can be compared. CDC: Age-adjusted estimates are only available at the county and place-level.

A state figure is a mean of the county estimates, weighted by the number of adults, computed by this site (site aggregate). PLACES has no state row, so the figure has no interval. The table is in name order and has no sort by figure.
Because these are modeled and not direct estimates, the data should not be used for ranking the overall health of any county, place, census tract, or ZCTA.

The data are a US government work in the public domain. Data set on data.cdc.gov. The boundaries and the links between ZIP Codes, counties and places come from the US Census Bureau.
