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

NOTE: Gray indicates insufficient data or a suppressed estimate.

The highest concentrations of Non-Hispanic Asian residents cluster in the northwestern suburbs around the Montgomery County corridor near Norristown and King of Prussia, where several zip codes exceed 15–25%, with one area north of Norristown reaching near 50% or above. A secondary elevated cluster appears in select zip codes east of Philadelphia extending into New Jersey, contrasting sharply with very low percentages (under 2%) in urban core areas of Philadelphia, Camden, Chester, and Trenton, which tend to have predominantly non-Asian minority populations. The western and southwestern suburban fringe also shows moderately elevated Asian population shares in the 8–15% range, suggesting a broad suburban arc of Asian settlement distinct from the lower-density urban centers.
