- Crude and age-adjusted estimates
CDC's PLACES project publishes model-based estimates of 40 health measures for Downey, in Los Angeles County, California: 114,355 residents in the 2020 Census, 88,937 of them adults.
In the 2025 release it estimates that 27.6% of adults have obesity (95% confidence interval 24.8–30.5%), similar to Los Angeles County's 26.5%, in line with the California figure of 27.8% (site aggregate), lower than the national estimate of 32.8%. Where intervals overlap the figures are described as similar, because the model cannot separate them.
Diagnosed diabetes: 11.8% of adults (95% confidence interval 10.8–13.0%) in the 2025 release, similar to Los Angeles County's 12.6%, in line with the California figure of 11.7% (site aggregate), similar to the national estimate of 12.0%.
Across the 40 measures published for both, the interval for Downey lies entirely above the Los Angeles County interval for 0 measures, entirely below it for 0 and overlaps it for 40.
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 Downey (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 Downey have obesity, according to PLACES?
PLACES estimates 27.6% (95% confidence interval 24.8–30.5%) 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 Downey?
PLACES estimates 11.8% of adults (95% confidence interval 10.8–13.0%) in the 2025 release. The national estimate in the same release is 12.0%.
Is Downey different from Los Angeles County on obesity?
The 95% confidence intervals for Downey and Los Angeles 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 Downey?
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 Downey 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.
