Married Couple (% of all Households) by Zip Code (ZCTA5) — Massachusetts

NOTE: Gray indicates insufficient data or a suppressed estimate.

Zip codes in the suburban belt west and south of Boston—particularly in areas corresponding to towns like Wellesley, Lexington, and Hingham—consistently register married-couple household shares above 70%, forming a prominent yellow-shaded arc around the metro core. In sharp contrast, urban zip codes in Boston proper, Springfield, and the Provincetown area on the outer tip of Cape Cod fall below 30%, reflecting higher concentrations of single-person and non-family households. Western Massachusetts displays considerable heterogeneity, with pockets of high married-couple rates in rural and exurban towns interspersed among lower-rate college towns such as Amherst and Northampton.
