ZipCrawl

NOTE: Gray indicates insufficient data or a suppressed estimate.

The smallest average household sizes, generally below 2.0, concentrate in the urban core zip codes immediately surrounding downtown San Antonio, likely reflecting higher concentrations of single-person households, apartments, and older housing stock. Larger household sizes of 3.0 or above form a distinct ring along the metro's suburban and exurban periphery, with particularly high values in the southern fringe near Von Ormy and scattered newer-development zip codes to the northeast toward New Braunfels. A notable contrast exists between the northwest sector, which displays moderate household sizes around 2.4–2.8, and the deep south, where several zip codes reach 3.5, suggesting younger families and multigenerational households in those areas.
