Household Average Size by Zip Code (ZCTA5) — Texas

NOTE: Gray indicates insufficient data or a suppressed estimate.

The Texas Panhandle and much of North Texas exhibit consistently elevated household sizes in the 2.8–3.5 range, likely reflecting family-oriented suburban and rural communities, while the southern tip along the Rio Grande Valley displays a striking mix of very high and very low values, suggesting demographic heterogeneity between multigenerational Hispanic households and retirement-heavy areas. Urban cores in Austin, San Antonio, and parts of Houston stand out with notably lower average household sizes (1.5–2.0), consistent with concentrations of single-person households and young professionals. The Big Bend and far West Texas region shows a distinct cluster of below-average household sizes, likely driven by sparse, older populations in remote communities.
