摘要
就南京市1981--1985年(简称前五年)及1986--1990年(简称后五年)居民的寿命表作了分析。结果提示:随着时间的推移,居民的各种寿命表指标均在发生改变,其中寿命表死亡概率、年龄别死亡率均不同程度在下降,而尚存率、预期寿命等均不同程度在提高。预期寿命男性由前五年的69.91岁增加到后五年的71.77岁,女性由73.81岁增加到75.43岁,明显高于全国同期水平。居民的尚存半数年龄亦由前五年的73.4岁后移至77.1岁,女性由74.6岁后移至78.4岁.
Indices of Nanjing life tables during 1981～1985 and 1986～1990 were ana-
lyzed. The results showed that all the indices varied with time within the past two five-year
periods. It was found that there was a decline in the probability of death of life table and the
specific death rate of age,and an apparent increase in the survival rate and life expectancy.
Life expectancy at birth in 1981～1985 were 69. 91 years in male and 73. 81 years in female,
whereas in 1986～1990 they raised to 71. 77 years and 75. 43 years respectively. The age of
half survival number increased from 73. 4 years to 77. 1 years in male and from 74. 6 years to
78. 4 years in female. These indices of Nanjing life table were better than that of the National
Life Table of the same period.
