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

NOTE: Gray indicates insufficient data or a suppressed estimate.

SNAP participation rates across Pennsylvania exhibit a clear urban-rural divide, with the highest concentrations (30–50%) clustered in zip codes corresponding to cities like Philadelphia, Reading, Scranton, and Erie, as well as pockets in north-central Pennsylvania. Suburban rings around Philadelphia and Pittsburgh generally report the lowest rates (under 5%), creating sharp contrasts with adjacent urban cores. The broad swath of central and south-central Pennsylvania maintains moderate rates (10–20%), while northwestern counties show notably elevated participation compared to their northeastern counterparts at similar population densities.
