Google’s overall workforce, for example, is currently 30.9 percent women, who make up 21.9 percent of tech positions and 25.5 percent of company leadership. At Facebook, women comprise 36 percent of global personnel, 22 percent of technical roles and 30 percent of leadership. Twitter’s numbers are similar, with 38 percent women overall, 17 percent in technical jobs and 33 percent in leadership. Most tech companies have reported comparable statistics in recent years. These numbers are certainly better than they were a few years ago, but the increase is marginal at best.
