The official site breaks it down by tech/non-tech/leadership: http://www.google.com/diversity/at-google.html

Interesting that non-tech is less male-dominated than tech, as expected, but even more white-dominated.

Same white, just fewer Asians.

Nothing to see here, all stereotypes confirmed :)

Speculation only: It's possible the non-white numbers are boosted by the development offices in Asia. They may employ large numbers of developers (who are likely to be 95% Asian), but lower numbers of managers compared to management-heavy offices like Mountain View.

Not at all interesting- that's how it is most places I've seen. All the upper middle class white people who like the 'romance' of tech but don't want to do low status/high effort things like programming go straight into management.

I'm going to guess that a huge majority of that 30% female workforce is in HR, marketing, and other non-engineering roles.

That's one of the interesting things. Statistically HR has a similar gender ratio as engineering, only reversed -- 72% of all HR professionals are women (http://www.bls.gov/cps/cpsaat11.pdf).

And where are the crowds crying out loud for diversity and bringing more men to HR?
