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. Wyoming sits #46 of 52 by ZIP count at income #16.

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 on a shorter ZIP list (178 codes · 171 cities). Household income averages $84,549 (16th of 52 by avg ZIP income). Compact geography means city pages carry more of the contrast than a giant county table; open the largest city first, then one smaller market, rather than scanning every ZIP.
The largest city, Cheyenne (86,283), holds a moderate share (~15%) 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 Cheyenne usually beats reading the state average alone.
Compact ZIP geography: the state page is closer to a directory than a mega-atlas. Prefer the largest city page and its primary ZIP over scanning every county, and keep the FAQ answers as the quick census totals.

What this shows Cheyenne 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.

Frequently Asked Questions
Is Wyoming compact enough to browse ZIP by ZIP?
Yes – 178 codes and 23 counties put Wyoming in compact geography. Prefer the largest city page and its primary ZIP; the roll-ups here are quick census totals, not a substitute for opening one urban and one thin-edge code.
Does Wyoming's above-median ZIP income mean every market is expensive?
No. The unweighted ZIP mean ($84,549) still mixes dense suburbs with thinner edges, and home values average $369,182. Open the densest metro and one thin-edge county before reading affordability from the state line alone.
Which Wyoming cities should I open first?
Start with Cheyenne (86,283, ~15% of ZIP population), then one mid-size market from the largest-cities chart. A two-ZIP compare inside vs outside Cheyenne usually beats reading the state average alone. Other large markets include Casper, Gillette, Laramie.
