Is it? The basis of the word civilization has to do with population and technology.

You wouldn't consider a small house with tens of miles of nothing around it civilization.

By the same token, due to population, a village would also be considered civilization.

I assume you mean civilization exclusively referring to cities with large skyscrapers and the like, in which case you'd be right but I haven't really ever heard of anyone who would act that way except maybe entitled city leftists.
