Household Average Size by Zip Code (ZCTA5) — Arkansas

NOTE: Gray indicates insufficient data or a suppressed estimate.

Northwest Arkansas zip codes, particularly in the Benton and Washington County corridor, display consistently higher average household sizes (3.0–3.5+), likely reflecting the region's rapid family-oriented suburban growth tied to major employers like Walmart, Tyson, and J.B. Hunt. In contrast, scattered zip codes across the south-central and eastern Delta regions show notably lower averages (1.5–2.0), corresponding to areas with aging populations, higher poverty rates, and persistent out-migration. Urban cores such as Little Rock and college towns like Fayetteville and Jonesboro contain pockets of smaller household sizes surrounded by larger-household suburban rings, illustrating a classic urban-suburban demographic gradient.
