Some amusing data about this in the US:

There's at least one[a] town/city called San Jose in at least[b] 4 US states. Not to mention other things named such (e.g. 2 different San Jose creeks in California, neither of which is in the San Jose metro - one in LA and one in Monterey)

[a] there appears to be 2 towns in new mexico called San Jose

[a.2] Illinois amuses me because there's a San Jose and St Joseph both, and both are small.

[b] There appears to be a tiny (pop 15) town called San Jose in Texas, but it's unclear if that's officially incorporated, etc.
