For the purposes of this quiz, the Upper Midwest includes Minnesota, Iowa, Wisconsin, Michigan, Illinois, Indiana, and Ohio.
These are NOT metropolitan populations.
this is the region you should be placing South and North Dakota as they are more likely associated with the Midwest in most resources vs. having them in the Northwest like you currently have them. or create a Great Plains region. basically check any geography resource to pull your regions from. otherwise nice quizzes.
why consider ohio, indiana, and illinois in the upper midwest? To me Upper Midwest has always included only the very northernmost parts of those states.
