What’s behind Islandia’s grade
On seven CDC estimates for adults, Islandia is healthier than 77% of U.S. towns, #304 of 755 in New York. Smoking holds the grade up (fewer adults who smoke than 93% of U.S. towns); no exercise pulls it down (better than 36%).
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). Islandia’s median household income is $116,313; among the 6,255 U.S. towns within 25% of that ($87K–$145K), it’s healthier than 53%, about where its income would put it.
Most New York towns score higher on these estimates than towns elsewhere, so within the state Islandia is healthier than 60% of graded towns, against 77% nationally.
