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

NOTE: Gray indicates insufficient data or a suppressed estimate.

The highest concentrations of Non-Hispanic Asian residents in Washington are sharply clustered in the Seattle-Bellevue-Redmond metropolitan corridor on the eastern shore of Puget Sound, where several zip codes exceed 25–50% Asian population. This dense cluster contrasts starkly with the vast majority of eastern Washington, where nearly all zip codes fall below 2%, with a notable exception in the Tri-Cities area near the southeastern border showing a moderate concentration around 15–20%. Western Washington outside the core metro area, including the Olympic Peninsula and coastal regions, also registers very low percentages, generally under 5%.
