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. Iowa sits #10 of 52 by ZIP count at income #27.

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 ($76,594) across a multi-metro ZIP mosaic (934 codes). Home values average $175,588. 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.
Population is dispersed across many cities (largest share ~7% in Des Moines). No single metro owns the narrative: scan the largest-cities chart for several peers, then pick counties from different regions before drilling to ZIP detail. Unweighted ZIP averages are especially noisy on this dispersed map.
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.

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 Iowa.
Frequently Asked Questions
How should I navigate Iowa's mid-breadth ZIP map?
With 934 ZIPs across 100 counties (population 3,046,945), 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 Iowa's above-median ZIP income mean every market is expensive?
No. The unweighted ZIP mean ($76,594) still mixes dense suburbs with thinner edges, and home values average $175,588. Open the densest metro and one thin-edge county before reading affordability from the state line alone.
Why doesn't one city define Iowa?
Population is dispersed (largest share ~7% in Des Moines). Scan several peers on the largest-cities chart, then pick counties from different regions before drilling to ZIP detail – unweighted ZIP averages are especially noisy on a dispersed map.
