Sweden has a government department for statistics and one data point they collect and publish is work statistics. The most gender segregated work places are dominated by women, with a few being around 99%. The only male dominated profession in top 5, last time I checked, was stonelayer, which was around 95%. In term of total gender segreation in the work force, about 15% of men and women work in gender equal profession. The majority, both men and women, work in a job where their gender outnumber the other gender by 2 to 1 or more. A common finding in studies conduced on this statistics is that gender segregation occurs also within a profession. Teachers is used as the typical example where gender segregation occur on both subject but also on level. It also get worse as people advance in their careers, with each "step" on the ladder being a point where the minority gender decrease.
