平均寿命是生命表中重要指标之一。它反映某时期出生的一批人按当时的年龄别死亡率计算每人平均可活多少岁。它是评价人口健康常用的综合性统计指标。作者使用1961年、1974年、1981年和1987年的统计资料,按蒋庆琅方法编制了黑龙江省人口1961、1974、1981和1987年寿命表,对寿命表中平均寿命作了分析。希望为人口研究和黑龙江省人口健康状况的评价提供参考依据。
The average life expectancy is one of the important indicators in the life table. It reflects how the average number of years old per person was calculated by the number of people born at a certain time based on the age-specific death rate at that time. It is a comprehensive statistical indicator commonly used to evaluate population health. Using statistical data from 1961, 1974, 1981, and 1987, the author compiled the life tables of population in Heilongjiang Province in 1961, 1974, 1981, and 1987 according to the method of Jiang Qingyi, and analyzed the average life span in the life table. I hope to provide a reference for population research and evaluation of the health status of Heilongjiang Province.
