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

NOTE: Gray indicates insufficient data or a suppressed estimate.

SNAP participation rates in the Chicago metro area exhibit a stark spatial divide, with the highest concentrations (30–50%) clustered on the South Side of Chicago—particularly around Englewood and extending southeast toward Gary and Hammond, Indiana. Suburban areas to the west and northwest, including Naperville, Schaumburg, and Palatine, consistently register rates below 10%, forming a low-utilization corridor. Pockets of elevated SNAP usage also appear in satellite cities such as Aurora, Joliet, and Elgin, suggesting that economic hardship extends beyond the urban core into specific older suburban centers.
