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

NOTE: Gray indicates insufficient data or a suppressed estimate.

Baltimore City and several surrounding zip codes in the Baltimore metropolitan area exhibit the highest SNAP participation rates, with multiple zones exceeding 30–50%, forming a pronounced cluster of food assistance dependency in the north-central part of the state. The Eastern Shore's lower Dorchester and Somerset County areas, particularly in the southeast, also display elevated rates above 25%, contrasting sharply with the affluent suburban zip codes of Howard, Montgomery, and Anne Arundel counties, where participation generally falls below 5–10%. Western Maryland presents a mixed pattern, with scattered zip codes in Allegany and Garrett counties showing moderate SNAP usage alongside pockets of very low participation.
