None of your data is broken out by major. That doesn't really help us, and you probably should refrain from going ad hominen immediately (troll, misinformed, are you serious etc) when your "facts" are far from conclusive.

I know in my college, in my two majors (mechanical engineer & computer science, 2007-2010) it was about 80/20 male/female in ME and 70/30 male/female in CS. The girls average was likely higher than the guys. I don't see how they are "dominating". You're numbers show there are more guys than girls in college - which was also true of my college which overall was 60/40 female/male. That doesn't mean there are more girls in majors related to startups like the ones we are talking about here (which I would highly doubt you can find numbers to say that).
