Sex imbalance in China.

摘要

The Chinese political icon Mao Zedong once said "women hold up half the sky". China is now faced with a serious threat of the sky crashing down. According to the 2010 Chinese census, the sex ratio at birth has climbed during the past three decades to an alarming 118 boys born for every 100 girls, the highest sex imbalance in the world. Without human intervention, the sex ratio at birth is projected to be between 103 and 107 boys born for every 100 girls. In China, only Tibet and Xinjiang have a balanced sex ratio for people younger than 20 years. A distorted sex ratio will result in many social problems. For instance, by 2020 an estimated 30 million Chinese men will be unable to find brides.
