Some of the world's leading Data Scientists are on the payrolls of Microsoft, Google, Facebook, Yahoo, and Apple. So, it'd be interesting to get their take on the infographics the tech giants have passed off as diversity data disclosures. Microsoft, for example, reported its workforce is 29% female, which isn't great, but if one takes the trouble to run the numbers on a linked EEO-1 filing snippet (PDF), some things look even worse. For example, only 23.35% of its reported white U.S. employee workforce is female (Microsoft, like Google, footnotes that "Gender data are global, ethnicity data are US only"). And while Google and Facebook blame their companies' lack of diversity on the demographics of U.S. computer science grads, CS grad and nationality breakouts were not provided as part of their diversity disclosures. Also, the EEOC notes that EEO-1 numbers reflect "any individual on the payroll of an employer who is an employee for purposes of the employers withholding of Social Security taxes," further muddying the disclosures of companies relying on imported talent, like H-1B visa dependent Facebook. So, were the diversity disclosure mea culpas less about providing meaningful data for analysis, and more about deflecting criticism and convincing lawmakers there's a need for education and immigration legislation (aka Microsoft's National Talent Strategy) that's in tech's interest?
