Population Non-Hispanic White % by Zip Code (ZCTA5) — Massachusetts

NOTE: Gray indicates insufficient data or a suppressed estimate.

The Boston metropolitan core and surrounding inner suburbs display markedly lower non-Hispanic white percentages, with several zip codes in Boston proper falling below 20-40%, creating a distinct cluster of demographic diversity in the eastern part of the state. Gateway cities such as Springfield, Holyoke, and Lawrence also stand out as darker-shaded pockets amid otherwise predominantly white surrounding areas, particularly visible in the western and northeastern regions. Cape Cod, the South Shore, and much of western rural Massachusetts remain overwhelmingly non-Hispanic white at 80-95%+, underscoring a sharp urban-rural demographic divide across the state.
