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. New Hampshire sits #44 of 52 by ZIP count at income #6.

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 (248 codes · 10 counties): average household income $102,353 and home value $404,868 usually track the largest city more tightly than in mosaic states. Median age sits near 47.6. Skip mega-state synthesis; jump from this profile into the top city and its primary ZIP for the street-level read.

Population is dispersed across many cities (largest share ~9% in Manchester). 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.

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.

Frequently Asked Questions

Is New Hampshire compact enough to browse ZIP by ZIP?

Yes – 248 codes and 10 counties put New Hampshire 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 New Hampshire's above-median ZIP income mean every market is expensive?

No. The unweighted ZIP mean ($102,353) still mixes dense suburbs with thinner edges, and home values average $404,868. Open the densest metro and one thin-edge county before reading affordability from the state line alone.

Why doesn't one city define New Hampshire?

Population is dispersed (largest share ~9% in Manchester). 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.

New Hampshire'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.
