Uber is aware that its culture needs to change, and that means understanding what its culture is. To that end, the ridesharing giant has posted its first-ever diversity report... and it's clear that the company suffers from the same homogeneity problems as its tech industry peers. Women represent 36.1 percent of its global workforce, and that number plunges to 15.4 percent when you look at technical roles. And not surprisingly, there's not a lot of cultural variety. In the US, just under half (49.8 percent) of Uber employees are white, while 30.9 percent are Asian. And those figures are exaggerated at the top -- 22 percent of executives are women, and 76.7 percent of them are white.
