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. Louisiana sits #29 of 52 by ZIP count at income #46.

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.
Lower ZIP-income footing ($59,685 · 17% below the national ZIP median) across 515 delivery areas and 64 counties. Home values average $177,087. Housing and income fields still vary sharply inside the state; begin with the largest city and its densest ZIP rather than treating the state mean as a uniform cost of living.
Population is dispersed across many cities (largest share ~8% in New Orleans). 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 Louisiana compact enough to browse ZIP by ZIP?
Yes – 515 codes and 64 counties put Louisiana 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.
What does Louisiana's lower ZIP-income footing change about this profile?
Household income across ZIPs averages $59,685 (17% below the national ZIP median). Housing and income still vary sharply inside the state – begin with the largest city and its densest ZIP rather than treating the state mean as a uniform cost of living.
Why doesn't one city define Louisiana?
Population is dispersed (largest share ~8% in New Orleans). 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.
