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

NOTE: Gray indicates insufficient data or a suppressed estimate.

The highest SNAP/food stamp utilization rates, exceeding 40-50%, concentrate in north St. Louis city and the immediate north county suburbs near Florissant, forming a contiguous corridor of elevated need that extends from the urban core outward. In stark contrast, the western and outer suburban zip codes—including St. Peters, St. Charles, and the far southwest portions of the metro—register near 0-5%, reflecting sharp socioeconomic divides along broadly racial and geographic lines. A transitional band of moderate usage (10-20%) is visible in the inner-ring suburbs ringing the city, particularly to the south and west of downtown St. Louis.
