For Asian Americans, it seems like educational attainment is actually higher where there's fewer of them, because fewer means they're more highly selected in moving there (whether from abroad or domestically).

Is that only true for Asians or for other groups too?

Like, are black or Hispanic Americans' educational attainments higher in places where they are a smaller minority, because those who self-selected to willingly move to places where they are a minority are often the educated? (For many Black Americans, selectivity in migrating to places where there are few blacks might be more domestic migration, unlike the effect for many Asian Americans and maybe for Hispanic Americans who became Americans by directly migrating there from abroad, but I wonder if the principle applies).
