Which states (and/or DC) are in the Midwest?

[Oldiesfreak1854]

Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Nebraska, North & South Dakota, Ohio, and Wisconsin.

Although I can see a case for Oklahoma or Kentucky, they are definitely more Southern culturally (and so is Texas.)  Although there are some similarities in rural/western Pennsylvania, I'd probably call it a northeastern state.

I take it there is no category for "border states." I might put MO, KY and WV in that category. And is Oklahoma a plains state or a southern state?

Yes, I think more plains though.

Hence my suggestion that a state be placed based on the region where a majority of the population resides. MO and OK are midwestern (if as I think it includes the plains) , KY is southern. WV is tough since it has significant populations in the Appalachian Northeast, the Appalachian South, and some of the Midwest along the Ohio valley. Since the more of the population matches with western and central PA, than with western VA and eastern KY, I put it in the Northeast since PA is there. TX has the same problem of a split between three regions.
