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 Iowa figure falls outside Knoxville’s likely range; at the ends of CDC’s ranges the grade could be anywhere from C− to A−.
What’s behind Knoxville’s grade
On seven CDC estimates for adults, Knoxville is healthier than 53% of U.S. towns, #72 of 140 in Iowa. Physical distress holds the grade up (fewer adults with frequent physical distress than 65% of U.S. towns); obesity pulls it down (better than 16%).
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). Knoxville’s median household income is $61,599; among the 9,302 U.S. towns within 25% of that ($46K–$77K), it’s healthier than 78%, more than its income alone would suggest.
