I'm Dutch as well and I have similar observations as mcv -- I live in the randstad region (concurbation of Amsterdam, The Hague, Rotterdam and Utrecht). Friends who work in construction having kids women with a higher education. I noticed that when I was in the dating scene, I didn't particularly care what the education of someone else was. However, I do notice that I have more in common with higher educated women since they have a higher tolerance for my geeky side, on average.
