Well also Rotherham in the UK is a town with over 100k people, though not US-style "small town", it's certainly not a city, and not even a particularly huge town (there are many 100k+ towns that aren't cities: the largest is Reading with nearly 1/4 million)

But that might be just a UK naming thing since "city" means something special (and isn't actually especially related to size: the smallest one is 1600 people).

But yes, perhaps it's not really a "small" town but just a town.
