ZipCrawl

NOTE: Gray indicates insufficient data or a suppressed estimate.

Married-couple households concentrate most heavily in the outer suburban ring, particularly in the western and northwestern zip codes near and beyond Waltham and Newton, where rates frequently exceed 60–70%. A sharp contrast emerges in the urban core around Boston, Somerville, and adjacent zip codes, where married-couple shares drop below 30%, forming a distinct low-percentage cluster. The southern suburbs around Quincy and Weymouth Town display moderate rates in the 40–50% range, serving as a transitional zone between the dense urban core and the higher-rate periphery.
