% of Population on Food Stamps or SNAP (Last 12 Months), by Zip Code (ZCTA5) — Houston Metro

NOTE: Gray indicates insufficient data or a suppressed estimate.

The highest concentrations of SNAP participation—exceeding 30-50%—cluster tightly in zip codes within and immediately south of central Houston, particularly in the Third Ward, Sunnyside, and Greater Fifth Ward areas, forming a distinct corridor of food assistance reliance. Suburban and exurban areas such as Katy, Sugar Land, The Woodlands, Friendswood, and League City consistently register below 5-10%, creating a sharp core-periphery gradient radiating outward from the urban center. Notable pockets of elevated SNAP usage also appear in portions of northeast Houston near the Aldine area and in select zip codes south of Pasadena, contrasting with adjacent lower-rate neighborhoods.
