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

NOTE: Gray indicates insufficient data or a suppressed estimate.

The highest concentrations of Non-Hispanic Asian residents, exceeding 25–50%, cluster in the inland zip codes stretching from the Mira Mesa and Rancho Peñasquitos corridor through Carmel Valley and into the Scripps Ranch area, forming a distinct band across north-central San Diego. In contrast, the large eastern zip codes beyond Santee and the southernmost areas near the U.S.-Mexico border register among the lowest percentages, generally below 5%. Coastal communities from Encinitas south through La Jolla and central San Diego neighborhoods display moderate representation in the 10–20% range, while National City stands out in the south with a notably higher Asian population share relative to its immediate surroundings.
