Why are the majority of the NPCs names of Japanese or Indian origin?

I don't mind the names, it only bothers me that they are not matching up to sims of that orientation. Sometimes it feels like it is cultural appropriation... But who minds, I suppose, I will just change the names if they matter enough to my save.

Edit: This is another thing with auto-generated sims, NONE of my black sims wear their natural hair, while white sims are wearing dreads and afros. Yes, it happens in reality, but it isn't absolutely everyone like it is in the sims.
