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

NOTE: Gray indicates insufficient data or a suppressed estimate.

The Baltimore metro area exhibits a stark racial geographic divide, with zip codes in the urban core of Baltimore City—particularly to the west and northwest of downtown—registering non-Hispanic white population shares below 10%, while northern suburban and exurban zip codes in Baltimore County beyond Towson reach 80–100%. A notable transition zone runs roughly along the city-county boundary, where percentages shift rapidly from single digits to 40–60%, and the southern portions of the metro near Columbia display moderate diversity with values generally in the 40–70% range.
