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. California sits #4 of 52 by ZIP count at income #8.

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.

High ZIP-level income footing ($101,666 average, 41% above the national ZIP median) across a huge delivery map (1,761 ZIPs · 58 counties). Home values average $772,713. Unweighted ZIP means still bury 10× spreads between coastal suburbs and inland edges, so treat the state line as a legend, then open the densest metros and one thin-edge county before trusting any single average.

Population is dispersed across many cities (largest share ~6% in Los Angeles). 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.

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.

Frequently Asked Questions

Why does California show so many ZIP codes on one profile?

California's 1,761 delivery areas span 58 counties and 1,175 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 California.

Does California's above-median ZIP income mean every market is expensive?

No. The unweighted ZIP mean ($101,666) still mixes dense suburbs with thinner edges, and home values average $772,713. Open the densest metro and one thin-edge county before reading affordability from the state line alone.

Why doesn't one city define California?

Population is dispersed (largest share ~6% in Los Angeles). 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.

California's figures come from ACS 5-Year Estimates (2019–2023), aggregated from ZIP Code Tabulation Areas via the HUD USPS Crosswalk. See our methodology for details.
