How the Health Grade works
  • Seven CDC estimates. Adults in fair or poor health, frequent physical distress, frequent mental distress, obesity, diabetes, smoking and no exercise (CDC PLACES, 2025 release). On each one a town earns the share of U.S. towns doing worse, and those shares are averaged. It’s the same score as our Healthiest towns in Illinois ranking.
  • Graded on a national curve. Every U.S. town with 1,000+ residents and all seven estimates (19,420 places) is lined up by score: A+ top 5%A next 10%A- next 10%B B+ to B−, next 30%C C+ to C−, next 30%D D and D−, bottom 15%
  • Not adjusted for income. Wealthier towns are usually healthier, and the grade shows that as it is. The similar-incomes bar compares Big Rock with U.S. towns whose median household income is within 25% of its own.
  • Modeled, not measured. CDC combines national survey answers with each area’s age, sex, race and income mix. Big Rock uses CDC’s own estimate for it. High blood pressure is left out because it tracks age more than anything else. The confidence line recomputes the grade with every estimate at the low, then the high, end of its range.

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 Big Rock door to door.
Close calls stay grayEvery figure has a margin of error. When the Illinois figure falls inside it, we don't call Big Rock better or worse.
CDC's own town estimateCDC publishes Big Rock directly, so these are its own figures.

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

Health estimates: CDC PLACES. Hospitals and star ratings: Medicare Care Compare (CMS). Health centers and shortage areas: HRSA. Town boundaries: U.S. Census Bureau.
