Household Average Size by Zip Code (ZCTA5) — New Mexico

NOTE: Gray indicates insufficient data or a suppressed estimate.

Larger household sizes of 3.0 or above concentrate heavily in the northwestern quadrant of the state, particularly across the Navajo Nation and surrounding tribal lands, where many zip codes reach 3.5 persons per household. In contrast, the central corridor around Albuquerque and Santa Fe, along with the southern border region near Las Cruces, displays notably smaller averages in the 1.5–2.2 range, likely reflecting higher concentrations of single-person and smaller urban households. Scattered zip codes in the southeastern plains and portions of the Rio Grande Valley show moderate values around 2.5–2.8, creating a transitional band between the high-occupancy northwest and the lower-density urban centers.
