Household Average Size by Zip Code (ZCTA5) — West Virginia

NOTE: Gray indicates insufficient data or a suppressed estimate.

Household sizes across West Virginia cluster most noticeably in the southern coalfield counties, where several zip codes fall below 2.0 persons per household, likely reflecting aging populations and outmigration in areas like McDowell and Mingo counties. The Eastern Panhandle near the Virginia border and scattered rural zip codes in the north-central region display notably higher averages approaching 3.0–3.5, consistent with younger family-oriented communities and exurban growth corridors. The contrast between the low-density purple pockets in college towns and mining communities versus the yellow-green zones in agricultural and suburban areas underscores significant demographic variation even within a relatively small state.
