Over the past couple of months, many of the largest technology companies in the world have published diversity reports detailing the composition of their respective workforces. In an earlier chart we reported that the majority of workers in tech companies is male, with the share of female employees ranging from 40% at Pinterest to 25% at Intel. At second glance however, the degree to which females are underrepresented in the tech industry is much more drastic than our previous chart suggested.
What most of the mentioned diversity reports have in common is the fact that they break down the workforce into tech and non-tech jobs. For non-tech jobs, the male to female ratio roughly mirrors that of the U.S. labor force as a whole for most companies. Looking at tech jobs (programmers, engineers, etc.) yields an entirely different result: women account for less than one in five tech jobs at six of the world's most renowned tech companies, including Apple, Google and Facebook.
