Google is only 2.5% black according to a quick search (and 3.5% Latino). That's all employees, not just developers. I'm not sure how that's even possible for a company of that size in America. AA may be underrepresented in tech overall but they certainly aren't in business, HR, legal, etc in my corporate experience so that number seems very low to me. I wonder if any analysis has been to done to determine if any biases or recruitment strageties resulted in those low numbers.

To Google's credit they are developing various pipelines to recruit underrepresented communities.
