It is absolutely true that the composition of Google's workplace does not match the diversity of the surrounding population. However that isn't the right thing to measure. You have to ask how it compares with the applicant pool. There are a lot of Hispanics in Silicon Valley. But there aren't a lot of Hispanics applying as software developers. And therefore without a lot of reverse discrimination, there is no way that Google's software developers can match the general population.

That said, Google does a lot to try to improve how many minority students go into software development. And tries to make its population as diverse as possible. Google truly would like to be more diverse than it is. But you can't hire people who don't apply.

(None of which is going to matter to activists whose minds are made up and who are just looking for someone to get mad at.)
