First off, only Norwegian source on this, so will try to include everything relevant below.
According to statistics, we will soon have the same gender imbalance among younger generations as China.
Since the beginning of our records in 1769 up to 2010, Norway had slightly more women than men. This is the norm, because while slightly more boys are born, women have higher life expectancy both from age-related deaths and risk/work-related deaths in their life.
But in 2010, and every year since, men are outnumbering women and the gap is only growing larger. This discrepancy comes from the fact that the overwhelming majority of immigrants arriving are men. Overall 73% of applicant are men, to the 27% women. Among children traveling alone it's 91% boys to 9% girls.
Sweden is seeing the same trend, only they are further ahead. Among their youth, there's currently 13% more young men than young women. With the current immigration trend, they're only 4 months away from sharing Chinas ratio.
Side effects of this growing discrepancy is of course disputed, but sociologists point out that the obvious increased difficulty of finding a partner means more men will likely suffer from drug abuse, get into crime, and have worse physical and mental health. It has also been linked with a lower life expectancy. In other words, it's not desirable when people can't find anyone to partner with.
I'm not sure what I think should be done, but I think it might be worth considering certain quotas to get in roughly equal gender distributions.
Thoughts?
