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. Tennessee sits #22 of 52 by ZIP count at income #42.

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 footing ($66,453) on a substantial ZIP map (628 codes · population 6,339,942). Home values average $247,477. Cost-of-living questions belong at county and ZIP scale here: the state average mixes unlike labor markets. 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.
Population is dispersed across many cities (largest share ~11% in Memphis). 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.
A mid-breadth ZIP set is small enough that city pages and the top-12 ZIP RankBars cover most contrast. Use county drill-downs when two metros sit in different economic zones; otherwise jump straight from this profile to a ZIP compare.

Frequently Asked Questions
How should I navigate Tennessee's mid-breadth ZIP map?
With 628 ZIPs across 95 counties (population 6,339,942), city pages plus the top ZIP RankBars cover most contrast. Jump to a two-ZIP compare when two metros sit in different labor markets rather than scrolling the full list.
Why is Tennessee's average ZIP income a weak relocation signal by itself?
At $66,453, the state mean blends unlike county labor markets (homes average $247,477). 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 Tennessee?
Population is dispersed (largest share ~11% in Memphis). 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.
