Ontario is healthier than its income would predict
Against all U.S. towns, Ontario is healthier than 16%. Against the 4,441 towns with similar household incomes ($35K–$58K), it’s healthier than 48%. Health Grade ↓
Written from the CDC, Medicare and HRSA data on this page. CDC PLACES 2025 release: modeled estimates for adults, not counts; “higher” and “lower” mean the Oregon figure falls outside Ontario’s likely range; at the ends of CDC’s ranges the grade could be anywhere from D− to B−.
What’s behind Ontario’s grade
On seven CDC estimates for adults, Ontario is healthier than 16% of U.S. towns, #133 of 142 in Oregon. Smoking holds the grade up (fewer adults who smoke than 47% of U.S. towns); fair or poor health pulls it down (better than 11%).
Health estimates follow income closely across the country: towns with higher household incomes usually score higher (a correlation of 0.77 across 21,157 graded towns). Ontario’s median household income is $46,308; among the 4,441 U.S. towns within 25% of that ($35K–$58K), it’s healthier than 48%, about where its income would put it.

On the 26 measures below that have a better and a worse direction, Ontario is better than Oregon on 0 and worse on 13; on the rest, the Oregon figure falls inside Ontario’s likely range, so we call them about the same. Disability and SNAP are described, not compared as better or worse.
