What’s behind Greenfield’s grade
On seven CDC estimates for adults, Greenfield is healthier than 20% of U.S. towns, #724 of 847 in California. Smoking holds the grade up (fewer adults who smoke than 54% of U.S. towns); fair or poor health pulls it down (better than 2%).
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). Greenfield’s median household income is $84,740; among the 10,413 U.S. towns within 25% of that ($64K–$106K), it’s healthier than 8%, so it sits below most towns with similar incomes, too.
Where Greenfield compares well: arthritis, 16.3% (U.S. 25.3%); cancer, other than skin cancer, 3.4% (U.S. 7.9%).
