This shouldn’t be downvoted. Except for colonizer languages, most languages in the world are coextensive with an ethnic group or closely related ethnic groups. Virtually everyone who speaks Bangla, Japanese, Korean, or Thai is ethnically Bengali, Japanese, Korean, or Thai.

That doesn’t mean that there wasn’t a lot of (often forced) assimilation or worse involved for that to happen.

e.g. it’s not like Japan didn’t have a “native population” that spoke a different language(s). The colonization just happened a few thousand years earlier than in the Americas.

Which are spoken by billions of people around the world. That's a huge exception.
