While I wouldn't want to be pedantic about words, "civilization" means living in cities. It differentiates nomadic people, or people who live in jungles from those people who settled down, built cities, established governments and agriculture and started building cultures that had longevity, permanence and made contributions to the future.
Civilization is very much an artificial construct. To describe just any ol' gathering of humans I would use the word "society".
Still not sure what you mean by that.
