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 Massachusetts figure falls outside Dennis’ likely range; Dennis’ figures come from ZIP codes 02660, 02638, 02639, 02670, 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 Dennis’ grade
On seven CDC estimates for adults, Dennis is healthier than 83% of U.S. towns, #165 of 279 in Massachusetts. All seven estimates beat the typical U.S. town. The strongest is mental distress (fewer adults with frequent mental distress than 94% of towns); the weakest is physical distress, still better than 54%.
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). Dennis’ median household income is $88,154; among the 10,151 U.S. towns within 25% of that ($66K–$110K), it’s healthier than 89%, about where its income would put it.
