A warning to sex ratio in China.

In recent years, the proportion of male babies has become larger and larger. According the Bulletin of Major Data from 1990 Census (Number 6) published by the State Statistical Bureau in May 20, 1991, on an average, the rate of male is 51.45%, and the rate of female is 48.55%; however, for 0-13 age group, the rate of male is 51.99%, and the rate of female is 48.01%. It means that, within 14 years before July 1, 1990, the sex ratio of newly-born babies had raised by 2.32%. With the further analysis, we can also see that the sex ratio in any year of the 14 years is higher than that of the total population. Moreover, the younger, the larger the proportion of male is and the smaller the proportion of female is. The unusual sex ratio will have a direct effect on marriage. In about 20 years, each year there will be 1.2 million males who will not be able to find a girl to marry. Therefore, it is imperative that macroscopic regulation and control of sex ratio be taken as an important part of family planning work.
