Which countries have the most unequal sexual distribution, and what are the consequences?

Question

I heard there are 20,000,000 more men than women in China.

sub-question- is it usual for there to be more men than women, or for more women than men, or does it usually work out about average?

Answer 1

China has been accused of "gendercide" and is coping with a lopsided male to female ration.

"in the early '80s, China began enforcing an ambitious demographic engineering policy to limit families to one-child, as part of its strategy to fast-track economic modernization. The policy resulted in a slashed annual birth rate of 1.29 percent by 2002, or the prevention of some 300 million births, and the current population of close to 1.3 billion.  

From a relatively normal ratio of 108.5 boys to 100 girls in the early 80s, the male surplus progressively rose to 111 in 1990, 116 in 2000, and is now is close to 120 boys for each 100 girls at the present time, according to a Chinese think-tank report... A slew of reports have confirmed the disturbing demographic trend.

In a 2002 survey conducted in a central China village, more than 300 of the 820 women had abortions and more than a third of them admitted they were trying to select their baby's s*x.

According to a report by the International Planned Parenthood Federation, the vast majority of aborted fetuses, more than 70 percent, were female, citing the abortion of up to 750,000 female fetuses in China in 1999.

A report by Zhang Qing, population researcher of the Chinese Academy of Social Sciences, said the gender imbalance is "statistically related to the high death rate of female babies, with female death rate at age zero in the city or rural areas consistently higher than male baby death rate." Only seven of China's 29 provinces are within the world's average s*x ratio. Zhang Qing's report cited eight "disaster provinces" from North to South China, where there were 26 to 38 percent more boys than girls. In the last census in 2000, there were nearly 19 million boys more than girls in the 0-15 age group."

Answer 2

China ...as a result of their one child per family policy

-Since males have traditionally been preferred there's many more males than females, making it difficult for many men to find wives

Answer 3

Genetically speaking it's about average, there is an unexplained slight bias for male offspring but this is only like a 1-2% bias.

Severe unequal sexual distribution usually has a cultural cause but i'm not sure about the consequences, sorry.

Answer 4

wales has 3 times as many women as men due to operatic singers and the men drink so much.

there are more females than males due to us being a lower class of species (males that is).
