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. Pennsylvania sits #2 of 52 by ZIP count at income #23.

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 ($77,864) across a continent-scale ZIP mosaic (1,795 codes). Home values average $227,282. 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, Philadelphia (1,526,206), 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 Philadelphia usually beats reading the state average alone.
Wide mosaics repay a shortlist: save two urban ZIPs and one rural ZIP from the tables below, then run a side-by-side compare before any relocation or affordability read. County pages are the right intermediate step when the ZIP list runs past a thousand codes.

What this shows Philadelphia 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
Why does Pennsylvania show so many ZIP codes on one profile?
Pennsylvania's 1,795 delivery areas span 67 counties and 1,610 cities – a mosaic large enough that this page is a map legend, not a street-level read. Drill to a county or city before treating any ZIP average as typical Pennsylvania.
Does Pennsylvania's above-median ZIP income mean every market is expensive?
No. The unweighted ZIP mean ($77,864) still mixes dense suburbs with thinner edges, and home values average $227,282. Open the densest metro and one thin-edge county before reading affordability from the state line alone.
Which Pennsylvania cities should I open first?
Start with Philadelphia (1,526,206, ~12% of ZIP population), then one mid-size market from the largest-cities chart. A two-ZIP compare inside vs outside Philadelphia usually beats reading the state average alone. Other large markets include Pittsburgh, Reading, Erie.
