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

NOTE: Gray indicates insufficient data or a suppressed estimate.

The vast majority of Wisconsin zip codes exceed 80% non-Hispanic white population, with the highest concentrations spanning rural areas of central, western, and northern Wisconsin. Milwaukee's urban core stands out sharply in the southeastern corner with zip codes dropping below 20%, representing the most pronounced racial diversity contrast in the state. Additional pockets of lower non-Hispanic white percentages appear around tribal nations in the north-central region, the Green Bay metro area, and select zip codes near Madison and Racine-Kenosha.
