Trinity County, in California, has 15,670 residents in the Census population estimates used by PLACES (12,928 adults). CDC's PLACES project estimates 40 health measures for its adult population using a statistical model, not a local survey.

In the 2025 release it estimates that 33.3% of adults have obesity (95% confidence interval 25.5–41.9%), in line with the California figure of 27.8% (site aggregate), similar to the national estimate of 32.8%. Where intervals overlap the figures are described as similar, because the model cannot separate them.

Diagnosed diabetes: 15.9% of adults (95% confidence interval 13.7–18.3%) in the 2025 release, above the California figure of 11.7% (site aggregate), higher than the national estimate of 12.0%.

Across the 40 measures with a published estimate, the county's interval lies entirely above the California figure for 25, entirely below it for 3 and includes it for 12. State figures are population-weighted county estimates computed by this site and carry no interval.

Report card: 40 measures by CDC category

Crude prevalence is the estimated share of all adults. Age-adjusted prevalence is standardised to the 2000 US standard population so that areas with different age structures can be compared. CDC: "Age-adjusted estimates are only available at the county and place-level."

Estimates by release

What each PLACES release published for Trinity County (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.

Questions and answers

What share of adults in Trinity County have obesity, according to PLACES?

PLACES estimates 33.3% (95% confidence interval 25.5–41.9%) 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 Trinity County?

PLACES estimates 15.9% of adults (95% confidence interval 13.7–18.3%) in the 2025 release. The national estimate in the same release is 12.0%.

Is Trinity County different from California on obesity?

The county's interval for obesity includes the California figure, so the two cannot be told apart by this model.

Can these figures describe a person who lives in Trinity County?

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 Trinity County 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.

Where does this data come from?

CDC PLACES: Local Data for Better Health, 2025 release (data updated 4 Dec 2025), which models Behavioral Risk Factor Surveillance System responses with Census population and American Community Survey data. Earlier releases (2022, 2023, 2024) are shown for reference. Boundaries and ZIP-to-county relationships are from the US Census Bureau.
