根据第三次全国人口普查资料附录中的(一)1953年全国5.67亿人口;(二)1964年全国6.95亿人口;(三)1982年河北浙江河南三省共1.66亿人口的每岁年龄组中男女人口数据,以五岁为组距,算出性别比,绘如图一。前两次普查中的110岁及以上组、第三次普查中的100岁及以上组,因各仅有数百人、故各合为一组处理。
According to the appendix to the third national census data, (a) the population of 567 million people in 1953 in 1953; (ii) the population of 695 million people in 1964; (c) the age group of 166 million people in three provinces in Hebei, Zhejiang, Zhejiang, and Henan in 1982 For male and female population data, the sex ratio is calculated using the age of five and the figure is shown in Figure 1. The number of people in the 110-year-old group or above in the first two census groups and the 100-year-old group or more in the third census were all handled together because there were only a few hundred people.
