Household Median Income by Zip Code (ZCTA5) — Maine

NOTE: Gray indicates insufficient data or a suppressed estimate.

Southern coastal Maine, particularly the Portland metro area and York County, exhibits the highest median household incomes in the state, with several zip codes reaching $100,000–$150,000, while a distinct band of lower-income zip codes ($30,000–$40,000) is concentrated in the rural northern interior and far eastern Aroostook and Washington counties. Central Maine displays moderate incomes generally in the $50,000–$70,000 range, with notable pockets of lower income around urban centers like Bangor and Lewiston-Auburn. The large, sparsely populated zip codes in the northwestern highlands appear as gray (no data) or low-income areas, underscoring the sharp economic divide between Maine's affluent southern coast and its rural interior.
