Married Couple (% of all Households) by Zip Code (ZCTA5) — Wisconsin

NOTE: Gray indicates insufficient data or a suppressed estimate.

Married-couple households predominate in the suburban and exurban zip codes ringing Milwaukee and in many rural northern and western Wisconsin communities, where rates frequently exceed 60–70%. The lowest concentrations—dropping below 30%—cluster tightly in Milwaukee's urban core, along with pockets in Madison, Racine, and smaller college or tribal communities such as those near Menominee County and Stevens Point. A broad swath of central and northwestern Wisconsin maintains moderate-to-high married-couple shares in the 50–65% range, while scattered rural zip codes with very high rates (above 75%) appear as yellow outliers in otherwise uniform regions.
