Sweden collect statistics on peoples job titles as a part of the process of collecting taxes, and based on that I find it slightly odd that there is such focus on programming. Only about 10% of professions is considered gender &quot;balanced&quot;, and a profession with 80% balance is quite in the middle. There is a bunch of professions which has 90%+, with several that has 99% of a single gender (primarily female professions, with some exceptions). The top one, never spoken about in gender politics, had about 4000 working females professionals to 1 male.<p>Since the article provided their personal theory, I will provide mine. I do not think its the work activity itself that matter, but that a person who picks between multiple choices of potential future professions, the deciding factor when everything else has been considered is the amount of people with similar life experience that one is likely to find. If you are a young parent, you have a minor preference for places which employ a lot of other young parents of the same gender. When everything else is equal, such preference can have a huge impact on gender statistics.
