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

NOTE: Gray indicates insufficient data or a suppressed estimate.

Zip codes in New Hampshire's northern tip and several rural areas in the central-western part of the state exhibit the highest married-couple household percentages, frequently exceeding 70–80%, while urban centers such as Manchester, Nashua, and the Concord area display notably lower rates, often falling below 40%. A distinct cluster of low married-couple percentages appears in the upper-central region near what corresponds to the Hanover-Lebanon area, likely reflecting the influence of college-town demographics. The southern tier of the state presents a heterogeneous patchwork, with affluent suburban zip codes showing elevated rates adjacent to lower-rate urban cores.
