Household Average Size by Zip Code (ZCTA5) — Wyoming

NOTE: Gray indicates insufficient data or a suppressed estimate.

Northeastern Wyoming zip codes, particularly in the Sheridan and Gillette areas, tend toward larger average household sizes (3.0–3.5+), likely reflecting family-oriented communities tied to energy and agricultural employment. In contrast, smaller household averages (1.5–2.0) cluster in south-central and southeastern zip codes, including areas around Laramie and Rawlins, where college-town demographics and older populations likely compress household size. The western mountain corridor from Jackson south through the Wind River Range displays moderate values (2.4–2.8), with notable pockets of very small households in resort-adjacent communities.
