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. South Carolina sits #32 of 52 by ZIP count at income #43.

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.
Mid-to-lower income with a contained ZIP set (424 codes · 46 counties). Average household income $63,759 and home value $226,094 should be read next to the largest city page, not as a national peer of mosaic states. Use the county RankBars to pick two markets, then compare ZIPs inside those counties.
Population is dispersed across many cities (largest share ~7% in Columbia). 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 South Carolina compact enough to browse ZIP by ZIP?
Yes – 424 codes and 46 counties put South Carolina 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.
Why is South Carolina's average ZIP income a weak relocation signal by itself?
At $63,759, the state mean blends unlike county labor markets (homes average $226,094). Cost-of-living questions belong at county and ZIP scale: start from the most populous counties, then drop to a thin-edge ZIP to see whether the mean is a real center or a blend.
Why doesn't one city define South Carolina?
Population is dispersed (largest share ~7% in Columbia). 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.
