As with many professions which historically were dominated by men, the STEM fields have seen a slow, but continuous, increase of women in the workforce over the last decades. One field is, however, standing out in the crowd, and is facing the opposite trend. Computer Science, which for a long time was one of the strongholds of STEM where women made up a substantial amount of the workforce, has seen quite a dramatic decrease since the 1990’s. From a decent 37% in the US in 1995 to only 24% in 2017. Sadly, current projections show that this number is most likely going to fall further in the next decade. Tech has become a male-dominated field, and it is not looking like it will change anytime soon. How did we end up here? Why are millennial women who grew up surrounded by computers and technology less likely to end up in the field than their baby-boom mothers? And finally—how do we turn the tide?
