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

NOTE: Gray indicates insufficient data or a suppressed estimate.

The highest SNAP participation rates, exceeding 35–50%, concentrate in central and west Philadelphia zip codes as well as Camden, forming a distinct urban core cluster of food assistance dependency. Surrounding suburban zip codes in Chester, Montgomery, and Bucks counties consistently fall below 5%, creating a sharp urban-suburban gradient that radiates outward from the city center. Notable secondary hotspots appear near Trenton, Norristown, and Chester, where SNAP rates of 20–35% interrupt the otherwise low-participation suburban landscape.
