Population Non-Hispanic Black % by Zip Code (ZCTA5) — Maryland

NOTE: Gray indicates insufficient data or a suppressed estimate.

The highest concentrations of Non-Hispanic Black residents, exceeding 50% and reaching near 100%, cluster prominently in Prince George's County south of Washington, D.C., and in portions of Baltimore City, forming a distinct corridor through the central part of the state. Western Maryland, the Eastern Shore, and much of the rural periphery display markedly lower percentages, generally below 10-15%, creating a sharp demographic contrast with the urban and suburban core. Several zip codes on the lower Eastern Shore around Salisbury and in Charles County in Southern Maryland show moderate concentrations in the 20-40% range, suggesting secondary clusters outside the primary Baltimore-Washington corridor.
