What is considered a “college town”?

[Santander]

There are multiple types of college towns.

Classic college town - < 150k population, major research university, young and highly-educated population, higher foreign-born population than average, active nightlife, cultural and sports amenities, large campus that anchors the community.
Examples - Lawrence, Bloomington, Ann Arbor

Hybrid state capital/college town - Most of the characteristics of a classic college town, but a fair bit larger in size and with more diverse lifestyle amenities than classic college towns. Generally considered good places for adults unaffiliated with the university to live in.
Examples - Madison, Columbus, at a stretch Austin, notably not Baton Rouge

Micro college town - A miniature and often slightly lame college town because the school lacks the size or institutional profile to hold a larger community together.
Examples - Vermillion, Orono

Enclave college town - College towns attached to or within a large metropolitan area. Distinct character for sure, but some of the life and character bleeds out due to the large metropolitan area. Generally more mixing with people unaffiliated with the college, and no problem for an adult to live there as a townie.
Examples - Boulder, Norman, Tempe

Town with a college - A small to mid-size city with a college, which does play an active role in the city, but is less indispensable to the community and doesn't have a large gravitational pull.
Examples - Terre Haute, Pensacola

Town of colleges - Boston
