Household Average Size by Zip Code (ZCTA5) — Charlotte Metro

NOTE: Gray indicates insufficient data or a suppressed estimate.

The largest average household sizes in the Charlotte metro concentrate in a distinct cluster northeast of the city center, with one zip code between Huntersville and Concord reaching approximately 3.5 persons per household, likely reflecting newer suburban family-oriented developments. Downtown Charlotte and its immediate surroundings exhibit the smallest household sizes—dropping to roughly 1.5–1.8—consistent with a high concentration of apartments, condos, and single-occupant housing typical of urban cores. The outer suburban and exurban ring, including areas around Gastonia, Kannapolis, and south Charlotte, generally maintains moderate household sizes between 2.4 and 3.0, suggesting a mix of established single-family neighborhoods and moderate-density housing.
