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. Washington sits #23 of 52 by ZIP count at income #11.

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.
A high-income state on a compact ZIP set (596 codes · 39 counties): average household income $90,905 and home value $511,186 usually track the largest city more tightly than in mosaic states. Median age sits near 43.5. Skip mega-state synthesis; jump from this profile into the top city and its primary ZIP for the street-level read.
The largest city, Seattle (837,792), holds a moderate share (~12%) 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 Seattle 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 Seattle 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 Washington compact enough to browse ZIP by ZIP?
Yes – 596 codes and 39 counties put Washington 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 Washington's above-median ZIP income mean every market is expensive?
No. The unweighted ZIP mean ($90,905) still mixes dense suburbs with thinner edges, and home values average $511,186. Open the densest metro and one thin-edge county before reading affordability from the state line alone.
Which Washington cities should I open first?
Start with Seattle (837,792, ~12% of ZIP population), then one mid-size market from the largest-cities chart. A two-ZIP compare inside vs outside Seattle usually beats reading the state average alone. Other large markets include Spokane, Tacoma, Vancouver.
