The gender disparity among Chinese children is about 119 boys per 100 girls. The rise has been sharp — in the 1980s there were about 108 boys for every 100 girls. As a reference, there are about 105 boys for 100 girls in the United States.
For further consideration:
There is concern that the disparity among Chinese children might lead to a marriage problem — at this rate, by 2020, there will be 30 to 40 million more males than females.
Some of the reason for the lopsidedness may be due to a rise in infanticide and abortion after the Chinese government adopted a one-child-per-family rule in the 1980s.
China has since relaxed the rule — most rural couples may have two children. Only families in larger cities are now subject to the one-child rule.
There are more than 1.3 billion people living in China — the largest population in the world.
