Over the past couple years, a number of the world’s biggest tech companies have engaged in quite a bit of public hand-wringing about their diversity numbers. While those companies release annual reports breaking down their respective demographics, it’s often up to third parties to collate all that information, to present a comprehensive view of diversity in the tech industry overall. This year, The Verge has done the necessary data-work, and produced some interactive graphs comparing the employee mix at Google, Facebook, Twitter, Microsoft, Apple, Amazon, and Intel. The key findings? While Facebook and Twitter are better than their big-tech peers at bringing people from both genders into leadership circles, no company’s executive ranks feature more than 23 percent women. Overall, women make up 29 percent of the U.S. tech workforce—a significant dip from 47 percent of the country’s overall workforce. Tech’s leadership is also overwhelmingly white—90 percent at Amazon, 87 percent at Apple, and 81 percent at Microsoft, for example. Outside of leadership circles, the major tech companies were 71 percent male and 60 percent white. Apple claims the highest percentage of people claiming Hispanic origin, while Amazon features the most black or African-American employees among its tech peers. You can check out the rest of the data on The Verge’s site. While most of the largest tech companies have instituted programs to shift their demographics over the long term, it may be years before these numbers diversify in a significant way.
