Household Average Size by Zip Code (ZCTA5) — Dallas Metro

NOTE: Gray indicates insufficient data or a suppressed estimate.

The Dallas urban core and adjacent zip codes exhibit the smallest average household sizes in the metro, with several areas near downtown Dallas dropping below 2.0, likely reflecting concentrations of single-occupant apartments and younger demographics. Larger household sizes of 3.0 or above cluster prominently in the outer suburban and exurban ring, particularly in the McKinney corridor to the northeast, the southeastern fringe near Mesquite, and pockets southwest of Fort Worth. A notable contrast exists between the low-density urban core and the high-household-size periphery, with mid-range values (2.4–2.8) forming a transitional band through established suburbs like Plano, Garland, and Arlington.
