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 New York figure falls outside Ontario’s likely range; Ontario’s figures come from ZIP code 14519, which may reach past town lines; at the ends of CDC’s ranges the grade could be anywhere from B− to A.
What’s behind Ontario’s grade
On seven CDC estimates for adults, Ontario is healthier than 79% of U.S. towns, #292 of 755 in New York. All seven estimates beat the typical U.S. town. The strongest is fair or poor health (fewer adults who rate their health fair or poor than 86% of towns); the weakest is obesity, still better than 55%.
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 $82,608; among the 10,582 U.S. towns within 25% of that ($62K–$103K), it’s healthier than 87%, about where its income would put it.
Most New York towns score higher on these estimates than towns elsewhere, so within the state Ontario is healthier than 61% of graded towns, against 79% nationally.
