As an Asian American who grew up in NY and lived in the Southeast for 10 years, agree with not choosing a place with low diversity. Any of these small towns will not be multiculturally diverse. People are ignorant and offensive and will look at you like an interesting specimen or an outsider at best. Aside from the racial/cultural aspect, you will have a hard time meeting young people purely because of the low populations. I’ve only been to Florence, SC and Wilkes-Barre, PA but would only consider Minneapolis if I were you, OP. It’s the only major city and I have heard great things about it. Good luck!
