About these numbers

How CDC estimates town health

They're modeled estimatesCDC combines a large national health survey with each area's age, sex, race and income mix to estimate local rates. Nobody surveyed Seneca door to door.

Close calls stay grayEvery figure has a margin of error. When the Illinois figure falls inside it, we don't call Seneca better or worse.

Why a ZIP codeCDC publishes towns like Seneca by ZIP code. We weight the ZIP codes that cover Seneca by how much of its land each one covers.

CDC PLACES: Local Data for Better Health, 2025 release. The Illinois figure combines its counties, weighted by adult population.
