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

NOTE: Gray indicates insufficient data or a suppressed estimate.

Northern California's rural and mountainous regions, particularly in the Sierra Nevada foothills and North Coast, display the highest non-Hispanic white population percentages, frequently exceeding 80%, while the Central Valley's agricultural corridor and Southern California's dense urban core—especially the Inland Empire and Los Angeles Basin—show concentrations well below 20%. The San Francisco Bay Area exhibits sharp intra-regional contrasts, with affluent coastal and suburban zip codes in Marin, Sonoma, and the Peninsula registering significantly higher white percentages than adjacent urban zip codes in Oakland, San Jose, and eastern Contra Costa County. San Diego County mirrors this pattern with a visible east-west gradient, and the far southeastern desert communities near the Imperial Valley consistently rank among the state's lowest.
