Immigration and emigration are big things in this. I don't know any other country where a bigger proportion of (native) emigration consists of females. Emigrants from Finland to the rest of the world (and especially the world excluding Asia) are overwhelmingly female, while in Finland lives for example more than 4 British males for every female, almost the same ratio for Dutch and Irish. There is 2-4 times more males than females of any western country living here, while in the UK, Germany, Italy, France lives much more Finnish native females than males, the sex ratio is about the "mirror image" of what it is here. Finland is basically a "SEA" country within EU for Brits, Dutch, Irish, Italians, Greeks, Spaniards... I don't even start now about muslim arabs, black africans...
It has also got much worse since the "2015" in the graph (done before the effects of the disaster of 2015's autumn-early 2016).
While the TV is full of programs which send Finnish females to the world like "Dream job in Australia", "Au pairs in [insert native English-speaking country]", "Maajussille morsian maailmalla" (
https://www.suomi24.fi/viihde/oho-s...ajussille-morsian-maailmalla-starttaa?ref=s24). YLE had a massively big program some years ago that had massive participation of Finnish women sending letters, it was literally dating program for American (USA) men and Finnish women, with the idea that the American men would move to Finland. No American women participated or Finnish men. It only consolidated the stereotype (based on truth) that Finnish-American (or any other white anglo) couples are always only Finnish women with the anglo-foreigner. If there would be similar program with Thailand and Finland, YLE would 100% surely make it only for Thai men to find Finnish women, "to not promote the stereotype". YLE is 100% funded by mandatory tax, no paid ads even.
This is what you get in the long run when you give women the right to vote and work outside the home.
