Yes, it's a pretty small town. My undergrad was approximately that size.

Of course, smaller exist! There are functioning towns in East Texas with less than 500 people in them! My favorite is Caledonia; cherished memories are that upon crossing the border my father would pull his best BB King impression and belt out the eponymous tune.

Hah, yeah I suppose it's relative. I guess a really small town I would think of having less than maybe 1,000 people, but 30,000 is about the smallest sized town I'd ever want to live in personally.

30k is either a small city or a very large building.
