The Atlas of Ethnic Diversity in Wisconsin is a clear and colorful reference to the spatial distribution and socioeconomic characteristics of the state's many ethnic groups. More than sixty groups, from African Americans and Armenians to Vietnamese and Welsh, are depicted in full-color maps and in tables and graphs derived from 1990 U.S. Census data.

Authors Kazimierz J. Zaniewski and Carol J. Rosen explain how the data was compiled and how best to interpret it. In introductions to each section, they provide historical and geographical explanations for the ways that various ethnic groups are distributed across Wisconsin. In addition, the Atlas includes an extensive bibliography and appendices of helpful maps and comparative data.
