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

NOTE: Gray indicates insufficient data or a suppressed estimate.

The highest concentrations of Non-Hispanic Asian residents in the Baltimore metro area are clustered in the western suburbs, particularly in and around Ellicott City and Columbia in Howard County, where several zip codes exceed 25% and approach 50%. This stands in sharp contrast to Baltimore City proper and the eastern portions of the metro, where most zip codes fall below 5%, reflecting a pronounced east-west demographic divide. A secondary pocket of moderate Asian population share (roughly 10–15%) appears near Towson and select northern Baltimore County zip codes, suggesting suburban spillover from both the Columbia/Ellicott City corridor and employment centers in the northern suburbs.
