Mississippi: Not Your Ordinary Average State

That would be Wisconsin. Mississippi is #50 in ranking what states are the most typical states in the United States. Of course, that means that Mississippi is the most atypical state in the USA. Here's a paragraph from the article:

Mississippi, on the other hand, is about as far away from the average state as you can get on most of the 12 measures included in this study. By some measures, Mississippi is the poorest and most rural state in the country. The average house in Mississippi is worth only about $71,000. (Only Oklahoma has a lower median housing value.) When you add it all up, Mississippi is so far away from the typical state on so many different measures that it ends up at the bottom of the list.
