A predominantly white working-class city
Janesville is predominantly white, with German, Polish, Irish, and Italian roots. The Latino population is growing, and there are small Asian and African American communities.
Janesville has around 66,000 residents, with a historically white population of German, Polish, Irish, and Italian descent. Long-established families, many tied to the GM unions, have shaped the demographic profile for generations.
The Latino community has grown over recent decades and now represents approximately 7% of the population, primarily of Mexican origin. Asian communities (Laotian, Vietnamese, Hmong) are small, and African Americans make up a smaller share than the metropolitan average.
The majority of residents are Christian, with a strong Catholic presence (traditional Polish and Italian parishes), Lutherans, and Evangelicals. Hispanic evangelical churches are growing rapidly. There is also a historic synagogue, a small mosque, and traditional African American Baptist churches in the city center.
