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

NOTE: Gray indicates insufficient data or a suppressed estimate.

The highest SNAP participation rates, exceeding 40–50%, concentrate in a tight cluster of zip codes immediately surrounding downtown San Antonio and the Von Ormy area to the southwest, forming a clear core of economic need. Outer suburban and exurban zip codes to the northeast near New Braunfels and Schertz, as well as the far northwest, generally fall below 10–15%, reflecting the more affluent commuter communities ringing the metro. A notable band of moderate SNAP usage (15–25%) extends south and southeast of the urban core, suggesting a gradient of economic vulnerability that diminishes with distance from central San Antonio but persists more strongly along southern corridors than northern ones.
