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

NOTE: Gray indicates insufficient data or a suppressed estimate.

The highest concentrations of Non-Hispanic Asian residents in Maryland cluster tightly in the suburban Washington, D.C. corridor, particularly in Montgomery and Howard counties, where several zip codes exceed 25–50% Asian population. This central Maryland concentration contrasts sharply with the Eastern Shore, Southern Maryland, and western Allegany/Garrett counties, which remain almost uniformly below 2%. A secondary but notably weaker band of moderate Asian population (5–15%) extends into parts of Anne Arundel and Prince George's counties, suggesting outward suburban diffusion from the primary D.C.-adjacent core.
