DuPage County, IL
921,213 residents, 719,635 adults (Census population estimates used by PLACES). 37 ZIP Codes and 31 places with estimates.
CDC's PLACES project publishes model-based estimates of 40 health measures for DuPage County, in Illinois: 921,213 residents in the Census population estimates used by PLACES, 719,635 of them adults.
In the 2025 release it estimates that 29.2% of adults have obesity (95% confidence interval 24.5–34.5%), in line with the Illinois figure of 34.0% (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: 10.0% of adults (95% confidence interval 8.5–11.7%) in the 2025 release, in line with the Illinois figure of 11.7% (site aggregate), lower than the national estimate of 12.0%.
Across the 40 measures with a published estimate, the county's interval lies entirely above the Illinois figure for 2, entirely below it for 19 and includes it for 19. 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 DuPage 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 DuPage County have obesity, according to PLACES?
PLACES estimates 29.2% (95% confidence interval 24.5–34.5%) 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 DuPage County?
PLACES estimates 10.0% of adults (95% confidence interval 8.5–11.7%) in the 2025 release. The national estimate in the same release is 12.0%.
Is DuPage County different from Illinois on obesity?
The county's interval for obesity includes the Illinois figure, so the two cannot be told apart by this model.
Can these figures describe a person who lives in DuPage 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 DuPage 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?
