As a Wisconsinite, I've always been confused why it's considered "midwest". Wisconsin is in the eastern half of the US, and at the very top. Should be called the "midnorth"
Well America used to be just a handful of colonies along the eastern seaboard, but then there was the whole manifest destiny thing. Going west meant heading out to the new frontier. Midwesterners are people who gave up midway.
"Midwest" was once called "West". Like, Ohio was "The West", with "The West" meaning anything west the coastal plain.
Then people went even further west, but they still wanted to call the west of the past "West" so they called it "Middle West".
You kind of see the same thing in Asia. To Europe, Jerusalem was in "The East". Heck, even Constantinople was in "The East?" Then people saw just how much East there was. So... Middle East?
As a born and bred Seattleite, I consider Wisconsin east coast. I also consider Montana east coast. Idaho? Not Midwest. East coast. Spokane? East. Hawaii? So far west it's east. Everything is east.
I'd argue it should be in The Rockies region. Not sure if that's a regional identifier out west like Appalachia is, but 1/2 of Idaho is in the Rocky Mountain range
I'm a product of the Idaho education system, and it's not great. Luckily got a start in Washington, so it didn't ruin me completely. But that result does not surprise me at all.
wyoming and colorado are so high? like nah bro ur j west. also ohio being lower than illinois is nuts. maybe a lot of people in the appalachia region bc here in toledo we know where we are.
my best guess is people who live in the appalachia region bring the percentage down. it is a stunningly gorgeous, non-midwesty-looking part of the state
My bet with Wyoming is that most of the (admittedly small) population is in the Eastern part of the state, like Cheyenne and Laramie, if kinda makes sense they'd see themselves as more "Midwest"
From the driver's seat of a semi, Colorado feels like bits and pieces of its neighboring states smooshed together. You got Utahrado, New Mexirado, Wyomirado, and, yes, Nebraskarado, which is probably where the Midwestern Coloradans live. The only part where I really feel like I'm in a distinct state is the high mountain forests that shoot down the middle of the state.
Denver is probably where it is because it's right at the intersection of quite a few of these biomes. I wouldn't be surprised to learn it's been a major trading center for about as long as humans have roamed the continent.
It makes more sense when you consider that for most of US history the country was significantly smaller than it is now. Originally the country pretty much just consisted of the East Coast - and France, England, and Spain still had large chunks of territory within the US's current borders.
Much of what's now considered the west wasn't captured from Spain/Mexico until much later. So basically just look at it from the perspective of the East Coast where the US originated. To them at that time what we consider the Midwest now would have just been the west. And the terms changed with the westward expansion.
Coastal part is The South. Inland, you get Southwest. Then there's the panhandle, and while I don't know much about what the locals think of it, from the driver's seat of a semi it's indistinguishable from the flatter parts of Oklahoma. (Meanwhile, one of my favorite truck stops is in the hilly part of Oklahoma: the Chocktaw travel center in Stringtown.)
