With performers it's pretty clear. In the past few decades, Asian musicians (including myself) have come to dominate the ranks of string players (not so much with winds and brass). When I was in school, however, it was more Korean and Japanese players, whereas now it's trending more and more towards Chinese students.

With the new emphasis on Diversity, Equity, and Inclusion however, I expect that we'll see more and more trends towards minorities that traditionally haven't necessarily been a part of classical music.
