This is pure, 100% anecdote, but, I remember at my first tech job, there were basically 3 teams working on different aspects of the product. I, a white male, was on a team with 3 other white males. There was another team of around 5 or 6 who were all Chinese. The last team was probably 10-15, all Indian.

All these people were damn good at their jobs, but it was rather interesting how the demographics fell.
