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

NOTE: Gray indicates insufficient data or a suppressed estimate.

Household sizes across New York State display a pronounced urban-suburban divide, with Manhattan and parts of downtown Brooklyn exhibiting the smallest average households (around 1.5–2.0 persons), while suburban zip codes in Staten Island, outer Queens, and Rockland/Orange counties cluster at the higher end (3.0–3.5+). Upstate New York generally falls in the moderate range of 2.2–2.8, though college towns and small cities such as those near Ithaca, Albany, and Syracuse show notably lower values driven by student and single-occupant housing. The southwestern tier and Adirondack regions display considerable heterogeneity at the zip code level, suggesting localized variation tied to rural community composition rather than broad regional trends.
