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

NOTE: Gray indicates insufficient data or a suppressed estimate.

The highest concentrations of Non-Hispanic Asian residents cluster prominently in the San Francisco Bay Area and Silicon Valley zip codes, where several areas exceed 50%, with additional notable concentrations visible in parts of the Sacramento region and pockets of the San Gabriel Valley in the greater Los Angeles area. Rural and inland zip codes throughout the Central Valley, Sierra Nevada foothills, and far northern California consistently register below 5%, creating a stark urban-rural divide. Southern California displays a more fragmented pattern, with high-percentage zip codes in the western San Gabriel Valley and parts of Orange County interspersed among areas with markedly lower Asian population shares.
