Of course you’re right that children of US Asian immigrants are ahead even of US whites, I mention this in my different comment in this thread. However, since there are few of them relative to other groups, they don’t affect the distribution much, so I didn’t mention this for the sake of clarity, as it didn’t detract from my main point.
There are not few of them relative to other groups. In fact there are more of them than several, more native groups, like Pacific Islanders, Native Americans, and Mixed Race people
