Birth-Control is one of the basic state policies of China, it was decided to be a basic policy in Sept 1982, and added to constitution in December in the same year. The policy mainly encourages late marriages, late pregnancies, less births and better births to control population. While affecting the population positively, some serious social problems should be considered. This review aimed to comprehensively analyse the impact of the only child policy on Sex ratio at birth in China. The study included a discussion of the knowledge of other scholars.
