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

NOTE: Gray indicates insufficient data or a suppressed estimate.

Zip codes in western Montana—particularly along the Flathead Reservation corridor near Polson, Ronan, and Pablo—display notably elevated SNAP participation rates, often exceeding 25–35%, forming one of the state's most pronounced clusters of food assistance reliance. Several zip codes in the southeastern portion of the state, likely overlapping with the Northern Cheyenne and Crow reservations near Lame Deer and Lodge Grass, also exhibit high SNAP usage in the 20–40% range, contrasting sharply with surrounding rural areas that tend to fall below 10%. The lowest participation rates cluster in suburban and exurban zip codes around Billings, Bozeman, and Helena, where values frequently drop below 5%, underscoring a clear urban-periphery and reservation-driven divide in food assistance dependency across the state.
