The verdict
Texas leads ZIP coverage at 1,935 ZCTAs (#1 of 52). That is not the income board: New Jersey's unweighted average ZIP household income is $121,992 (#1 of 52) on 595 ZCTAs. Wisconsin sits #15 of 52 by ZIP count at income #22.

ZIP-count and income are separate boards among 52 reporting states and territories. Income is the unweighted mean of each ZIP's ACS 2019–2023 median household income, so a rural code counts the same as a dense metro.
Above-median income ($78,126) across a multi-metro ZIP mosaic (772 codes). Home values average $248,845. Population-unweighted ZIP averages give rural codes the same vote as metros, so the state mean is a compromise: sort counties by population, then compare one urban ZIP against one rural ZIP before reading relocation or affordability stories from the headline alone.
The largest city, Milwaukee (808,042), holds a moderate share (~14%) of state ZIP population. Expect a primary metro plus a long tail of mid-size markets: the top-cities chart and county RankBars both matter, and a two-ZIP compare inside vs outside Milwaukee usually beats reading the state average alone.
A mid-breadth ZIP set is small enough that city pages and the top-12 ZIP RankBars cover most contrast. Use county drill-downs when two metros sit in different economic zones; otherwise jump straight from this profile to a ZIP compare.

What this shows Milwaukee leads, but several peers sit close enough that this top-10 chart is a shortlist, not a single-city story – compare two of those metros before trusting the state mean.

Above-median income states still hide metro splits. Use Census ACS for income, and HUD Fair Market Rents when rent vs the state mean is the question in Wisconsin.
Frequently Asked Questions
How should I navigate Wisconsin's mid-breadth ZIP map?
With 772 ZIPs across 72 counties (population 5,686,814), city pages plus the top ZIP RankBars cover most contrast. Jump to a two-ZIP compare when two metros sit in different labor markets rather than scrolling the full list.
Does Wisconsin's above-median ZIP income mean every market is expensive?
No. The unweighted ZIP mean ($78,126) still mixes dense suburbs with thinner edges, and home values average $248,845. Open the densest metro and one thin-edge county before reading affordability from the state line alone.
Which Wisconsin cities should I open first?
Start with Milwaukee (808,042, ~14% of ZIP population), then one mid-size market from the largest-cities chart. A two-ZIP compare inside vs outside Milwaukee usually beats reading the state average alone. Other large markets include Madison, Green Bay, Racine.
