It is a documented (aka scientifically proven) fact that women generally prefer to work with people and men prefer to work with things. There are exceptions, of course.

In my 20+ years working in IT I met a single woman that was a developer and chose to stay a developer; a few moved from development to project management or operations, but most never wrote a line of code after graduating college, jumping directly in PM, ops or any role that allowed moving away from coding. I do not have any good explanation for this, my first sentence doesn't fully explain this.
