A survey on the sex ratio at birth in Beijing]

A survey was conducted on the sex ratio at birth in Beijing for the period between 1964 and 1982. In the 1960s, birth control ideas and plans were first introduced. In the 1970s, birth control measures were gradually taken to curb the population growth. In the 1980s, the policy of 1 child for each married couple was adopted and put into practice. Although the birthrate is being maintained at a low level, the number of childbearing age women has increased, and the birthrate has shown some increase. Statistics show almost equality in the sex at birth, but the number of newborn boys is slightly higher than that of newborn girls. Under the influence of Chinese tradition, a great many people in the countryside still prefer to have boys rather than girls, and they might have reported fewer newborn girls than the actual number. The average sex ratio for the past 3 years has still been close to a balance. With the practice of 1 child for each family, the sex ratio has been maintained close to a balance. This overall situation is made possible because of the development in the quality of birth and eugenics and the improvement in health care.
