China's one-child policy was introduced by leader Deng Xiaoping in 1978 as a temporary means of coping with unenployement and food shortages.
Enforcement levels vary from area to area, with heavy fines and punishments levied on those who don't comply.
Over the past 30 years, the policy has led to widespread forced abortions, sterilisations and female infanticide.
Encouraged by the family planning policy, a woman in China undergoes a voluntary abortion every 2.5 seconds, giving the country one of the highest abortion rates in the world.
A longstanding preference for boys!!! has created a surplus of 24 million men, as girls :( are more likely to be aborted!
