> And Silicon Valley of late has faced criticism over a lack of diversity among its ranks, which are overwhelmingly white and male. Facebook, for example, recently disclosed that just 31 percent of its 6,500 workers worldwide were women, and in its United States offices, more than half of all employees are white.

These are two wildly different statistics to group together. 31% is low for females in the work place. However, programming is in the archetypal "male" job category along with doctors, lawyers, etc. 31% is actually the ratio of female lawyers in the US. It's also markedly better than the amount of females in executive officer positions in Fortune 500 companies, which sits at 15%.

As for the latter: of course more than half of Facebooks US employees are white! More than half of all Americans are white! Non-hispanic whites are 64% of the population, if you include anyone who self-identifies as white or European American you're at 72%. What is Facebook supposed to do, black it up?
