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. Indiana sits #14 of 52 by ZIP count at income #30.

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 ($73,644) on a substantial ZIP map (775 codes · population 6,483,792). Home values average $193,531. 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.

The largest city, Indianapolis (910,148), holds a moderate share (~14%) of state ZIP population. Expect a primary metro plus a long tail of mid-size markets: the top-cities chart and county RankBars both matter, and a two-ZIP compare inside vs outside Indianapolis usually beats reading the state average alone.

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 Indiana's mid-breadth ZIP map?

With 775 ZIPs across 92 counties (population 6,483,792), 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 Indiana's average ZIP income a weak relocation signal by itself?

At $73,644, the state mean blends unlike county labor markets (homes average $193,531). 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.

Which Indiana cities should I open first?

Start with Indianapolis (910,148, ~14% of ZIP population), then one mid-size market from the largest-cities chart. A two-ZIP compare inside vs outside Indianapolis usually beats reading the state average alone. Other large markets include Fort Wayne, Evansville, South Bend.

Indiana'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.
