PIP: From July to December of 1982, a sample survey of fertility was conducted of childbearing females between the ages of 15 and 49 in Shanghai. The results of this survey can be summarized by the following points: (1) The percentage of females of childbearing age is very high, and the situation in the suburbs is even more serious than that inside the city. This is the major reason for a large scale population increase in Shanghi. (2) The marriage rate is high, the divorce rate is low, and the people who remain single in their lifetime are few. This stable family and marriage situation provides a favorable condition for population growth. (3) The average marrying age for childbearing females has gradually risen in recent years, but this trend is now reversed. More and more people are getting married when they are young. (4) Fertility for childbearing aged females decreases according to the increase in their age. In the last two years, however, this downward trend has been reversed, and fertility is gradually increasing again. The above points show that family planning and birth control have entered the most crucial period in Shanghai. Efforts and enforcement should be strengthened in the area of family planning, and no relaxation should be allowed so that the goal of controlling rapid population growth may be achieved.
