Interesting look at the economics of geography. Elena Holodny:
In more expensive states like California, you can afford comparatively less than average. In less expensive states like Mississippi, you can buy relatively more.
In other words, $100 doesn’t buy $100 worth of goods in one state, and buys more in another state.
Let’s look at Ohio, which is a low-price state, as an example of what the numbers on the map mean. $100 there will buy you goods and services that would be worth $112.11 at the national average price level
Here in Hawaii $100 is worth $84.18. Ouch.
