Interestingly, the gender ratio of immigrants to America from South Korea isn't 50-50 as one would expect but closer to 60% women. For Japan, another state struggling with fertility, this ratio is about 75%.
This is not particularly surprising in the light of the fact that Japan and South Korea are two of the most misogynistic societies in the developed world.
It's essentially impossible to be both a wife and mother as well as have a thriving career in both those countries. Can anyone blame them for opting out?
Could be something to do with chances for mating, Asian women got much higher chance to find a western husband compared to Asian guys finding a western female to marry them. In south east Asia people immigrate because of financial struggle so they don't care about this too much but in first world Japan and Korea, where people immigrate because of other reasons, it might be a factor.
