Just a thought, but what about countries where the ratio of men to women is way out of whack like China. I think I heard that by 2050 there would be 9 men for every female. (Really sucks to be in China)
Sex ratio in China (source):
- at birth: 1.133 male(s)/female
- under 15 years: 1.17 male(s)/female
- 15-64 years: 1.06 male(s)/female
- 65 years and over: 0.93 male(s)/female
- total population: 1.06 male(s)/female (2011 est.)
Unless China is headed for some sort of a cataclysm there's no way the rate will change to something like 9 in four decades.
The most unbalanced ratio seems to be in Qatar:
- at birth: 1.056 male(s)/female
- under 15 years: 1.06 male(s)/female
- 15-64 years: 2.44 male(s)/female
- 65 years and over: 1.36 male(s)/female
- total population: 1.99 male(s)/female (2011 est.)
Kuwait is not far behind, either. By looking only at the sex ratios it seems to me that is good to be a man in the Arabic speaking countries and a woman in the Russian speaking ones.
