If they are world-wide, I find it quite interesting how closely the location of the Google offices where software development occurs[1] matches the ethnicity numbers.
Notably, there is only one development office in Latin America (and none in Spain/Portugal), and the only development office in the Middle East or Africa is Tel Aviv (not clear what ethnicity the workers there would class themselves as).
I'm not aware of any world-class Computer Science programs in Africa. There are some decent ones in South Africa, Nigeria and Kenya, but increasing the number would be a problem worth tackling.
