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). Chelmsford’s median household income is $140,629; among the 3,509 U.S. towns within 25% of that ($105K–$176K), it’s healthier than 88%, about where its income would put it.
