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

NOTE: Gray indicates insufficient data or a suppressed estimate.

Non-Hispanic Asian population concentrations in Wisconsin are most pronounced in the southeastern corner around the Milwaukee metro area and in a distinct cluster in the central-eastern part of the state near the Fox Valley/Appleton-Oshkosh corridor, where several zip codes reach 8–15% or higher. Secondary pockets appear in the Madison area, Eau Claire, and La Crosse in the western part of the state, likely reflecting university communities and regional employment centers. The vast majority of rural zip codes across northern and western Wisconsin remain below 2%, creating a sharp urban-rural demographic contrast.
