摘要/Abstract

摘要： 本文选用我国4次全国人口普查资料中分年龄性别人口构成的原始数据经移动平均修匀后分析了两性高老龄各年龄队列人口在相邻普查期间的生存率及其差异随龄变化，以及每次普查人口高老龄组年龄别性别比。结果表明，两性生存率随龄迅速下降的趋势进入90岁以后的高老龄组将变平甚或上升；老年组男性年龄别生存率始终低于女性的现象在进入90岁以后的高老龄组差异迅速缩小并转而反向扩大。结果预示，尽管男性平均期望寿命低于女性，但并不表明男性的生理寿命低于女性。

Abstract: The original data of age and sex-specific constitution of population from the four censuses of China after smoothed by moving mean are ultilized to analyse the change of two-sex age-specific survival rates and their difference during intercensal periods and age- specific sex ratios of each census at older ages. The results show that the trend of rapid decline of two-sex survival rate with age levels off and even rises at older ages over 90. At old ages male age-specific survival rate is lower than that of female, but at the advanced ages over 90 this difference lessens and then turns to enlarge reversely. The results imply that although male average life expectancy is shorter than that of female, genetic life-span of male is not shorter than that of female.

Key words: Older ages, Age-specific survival rate, Sex ratio , Two-sex difference
