>The author cites the pew study [0] that claims less than 10% of the "US black population" is foreign born.

Yes, when I saw that it was clear to me that being "foreign born" said very little about the population. For example, English can still be a 2nd or 3rd language for recent immigrants with US born children, especially in California and Texas.

>I figure that answers your question and implies your nuance likely wouldn't change anything.

I disagree, immigrants are most likely unevenly distributed.

You're not disagreeing with me. I explicitly raised the possibility of uneven distribution in my reply.

That said, you could probably hunt for some school-level stats in the bay area and make an educated guess.

I misread, thanks for clarifying.
