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

NOTE: Gray indicates insufficient data or a suppressed estimate.

The highest concentrations of Non-Hispanic Asian residents cluster in the San Gabriel Valley east of Downtown LA, where several zip codes exceed 50%, forming a distinct corridor that extends from Monterey Park through Rowland Heights and into the Diamond Bar area. A secondary concentration appears in the Garden Grove–Westminster area of Orange County, likely reflecting the established Vietnamese American community, with surrounding zip codes in Irvine and Cerritos also showing elevated percentages in the 25–50% range. By contrast, South Los Angeles, the Antelope Valley fringes, and much of western Santa Ana register among the lowest shares at under 5%, creating a sharp demographic boundary with adjacent high-concentration areas just a few miles away.
