Union’s Health Grade: A

On seven CDC health estimates for adults, Union is healthier than 85% of U.S. towns and 77% of California towns.

BSelf-rated healthAPhysical distressAMental distressA+ObesityBDiabetesASmokingB+Exercise
All U.S. towns we grade (19,420)Healthier than 85%
Less healthyHealthier
California towns we grade (1,056)Healthier than 77%
Towns with similar incomes, $100K–$167K (3,999)Healthier than 55%

Wealth explains part of the grade. Union is healthier than 85% of U.S. towns overall, but against towns with similar incomes its edge is smaller.

These are estimates. At the ends of CDC’s likely ranges, Union could be anywhere from B+ to A.
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 California 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 Union 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. Union 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 Union door to door.
Close calls stay grayEvery figure has a margin of error. When the California figure falls inside it, we don't call Union better or worse.
CDC's own town estimateCDC publishes Union directly, so these are its own figures.

CDC PLACES: Local Data for Better Health, 2025 release. The California 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.
