China’s one child policy has had serious effects on the culture. Since the Chinese culture values sons over daughters, it has lead to what some refer to as “gendercide” as daughters are often aborted. This has lead a sever imbalance of 103-107 boys per 100 girls. Having a son ensures the passing on of the family name — ancestry worship is common in some Asian cultures — and parents see sons as a means to be supported in their elderly years. The impact on China has been so huge, that the Chinese government has lifted the three-decade one child policy and now enforces a two child policy.
But after 30-years, the impact has already been made and the lifting of this policy will not be felt for at least another 30-years.
