Conversely, the large metros in which highly educated people are the least segregated include Orlando, Tampa, Miami, and Las Vegas in the Sunbelt, as well as Providence, Hartford, Minneapolis-St. Paul, Rochester, and Buffalo in the Frostbelt.
I live in one of these places (well, not currently) and it's accurate that there isn't any congregation of college grads living in the same area that I'm aware of. There are multiple areas where there are more living compared to other areas, but none that is dominated by that demographic. It's interesting though, because rent and cost of living is pretty low, there are a decent amount of tech companies, though none are huge. Maybe it's because there isn't a surplus of "high-end" neighborhoods.
