Then there were additional 3-4 professions with exactly 99% gender segregation. Mechanics (male), nurse secretary (female), but I don't remember the names of the other. All those professions existed where for every minority gender there where hundred or hundreds employed of the majority.

Is this proof of systemic sexism, and if so, what conclusion can we draw? Remember that in Sweden the number of employed women and men is only off by less than 1%, and only 12.5% of the population work in a profession where the majority gender is lesser than 150% to the minority. Of those 12.5%, men was that year slightly more likely to work in a gender equal profession.
