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

NOTE: Gray indicates insufficient data or a suppressed estimate.

The Baltimore metro area exhibits stark racial segregation, with zip codes in west and northwest Baltimore City displaying Non-Hispanic Black population shares exceeding 80–100%, forming a dense high-concentration cluster that extends into portions of Baltimore County's Randallstown and Owings Mills corridors. In sharp contrast, zip codes to the north around Towson and the far northeastern suburbs register below 10–15%, as do several southern and southwestern areas near Ellicott City and parts of Howard County. Columbia and its surrounding zip codes occupy a moderate middle range of roughly 20–40%, serving as a transitional zone between the heavily Black western communities and the predominantly non-Black outer suburban ring.
