Quick answer: This page compares all 50 US states on a 2026 classroom snapshot: cost-of-living (COL) index where 100 = the US baseline (a lower index means cheaper relative to that baseline), illustrative estimated annual cost of living, median household income, combined average sales tax, and 87-octane gas. In this dataset, Oklahoma has the lowest COL index (83.5, about $41,750/yr illustrative COL), Massachusetts leads median income ($104,828; New Jersey is #2), five states have no state sales tax (AK, DE, MT, NH, OR), and Indiana shows the cheapest gas ($3.356/gal, June 2026 AAA).

FAQ

Answers about what this explorer shows and how to use it. Educational snapshot — not relocation or tax advice.

What does the US States Data Explorer show?

A 2026 classroom snapshot comparing all 50 US states on cost-of-living index (100 = national baseline), estimated annual cost of living, median household income, combined average sales tax, and 87-octane gas price. The hub includes a choropleth map, sortable table, per-state detail modals, CSV export, and the Couple's State Ranker dual-player game.

How do I read the cost-of-living index on this page?

A lower COL index means lower cost of living relative to the US baseline of 100. Use the map color selector or click table column headers to sort states by COL index or the other metrics.

How do I open a dedicated page for one state?

Click a state name in the sortable table or the permalink in a state's detail modal. Each state has an indexable page at /50states/{slug} (for example /50states/california) with the same core numbers plus an FAQ.

What is the Couple's State Ranker?

A dual-player mode on this hub: two people independently rank each state into five bins, then the tool shows a ranked list of states that score Maybe or higher for both players, based on combined scores.

Where does the explorer data come from?

Sales tax from Tax Foundation; income and cost of living from BEA / ACS; gas prices from AAA (June 20, 2026 snapshot noted on the hub). Educational snapshot — not relocation or tax advice.

Can I export the state table?

Yes. Use the download control in the header to export the state dataset as CSV from the explorer.

How do I compare a salary between two states?

Type a salary, pick the state you earn it in, and the state you are considering. The result multiplies your salary by the other state's cost-of-living index divided by your state's index. It is purchasing power in this snapshot, not a tax-equalized job offer.

What does a lower cost-of-living index mean for a household?

An index under 100 means this snapshot's price basket is cheaper than the US baseline of 100. It is not your rent, grocery bill, or tax return.

How to use this explorer

  1. Read the quick answer for the lowest cost-of-living index, the highest median income, and the cheapest gas in this 2026 snapshot.
  2. Choose two states and a salary in Compare two states. The headline multiplies your pay by the destination cost-of-living index divided by the source index.
