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

NOTE: Gray indicates insufficient data or a suppressed estimate.

The highest SNAP participation rates, exceeding 30–50%, concentrate in central and south Phoenix zip codes, forming a distinct corridor running roughly north-south through the urban core west of Tempe. Scottsdale, Gilbert, and the far southeastern portions of the metro exhibit consistently low participation rates below 5%, reflecting the affluent demographic profile of the East Valley suburbs. A notable gradient is visible moving westward from Scottsdale toward central Phoenix, where SNAP usage climbs sharply across just a few zip code boundaries, underscoring stark socioeconomic divides within relatively short geographic distances.
