All ISO 639-1 Languages with a Map

also with constructed languages, at most there should only be Esperanto

I think a big part of it is preserving languages. Marathi, Gujarati, Oriya, etc. Aren't going anywhere. But Manx, Cornish, Welsh, Navajo, etc. are endangered. Having an ISO 639-1 Code helps bring awareness. Other endangered languages don't have that kind of impact that the celtic languages did, or the local government doesn't want them preserved.

Not even really tho. They make a distinction between Bosnian and Croatian when linguists generally agree they are dialects of the same language, Serbo-Croatian, but the speakers would consider themselves different. But they also break up Akan into itself and Twi, even though they are seen as generally a single ethnic group.

Also, they include about 40 european languages but only eight native american languages, like 3 Austronesian, and only 3 Sino-Tibetan. They also for some reason include the official languages of SA but then only include a few other African languages.

I know it's arbitrary but this entire thing makes 0 sense and it makes me want to smash my head against my wall and it was probably just made to make Europeans happy by recognizing their multiple barely different languages but then just saying, "screw the rest of the world it's not like they matter".
