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

NOTE: Gray indicates insufficient data or a suppressed estimate.

The highest SNAP participation rates, exceeding 30–50%, concentrate in southeastern D.C. and adjacent Prince George's County zip codes, with a particularly prominent cluster just south and east of the D.C. core appearing in yellow and green tones. In stark contrast, the western and southwestern suburbs—including areas around Tysons Corner, much of Fairfax County, and Loudoun County—register near 0–5% participation, forming a broad swath of deep purple. Moderate SNAP usage (10–20%) appears in transitional zones such as parts of Gaithersburg, Rockville, and several Prince George's County zip codes east of Bowie, suggesting a geographic gradient that closely tracks the region's well-documented east-west income divide.
