CDC PLACES 2025 · adults 18+ · CDC's estimate for Oak BrookOak Brook’s Health Grade: A
On seven CDC health estimates for adults, Oak Brook is healthier than 87% of U.S. towns and 87% of Illinois towns.
Wealth explains part of the grade. Oak Brook is healthier than 87% of U.S. towns overall, but against towns with similar incomes its edge is smaller.
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 Oak Brook 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. Oak Brook 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.
