小人群寿命表编制方法

本文以北京市一个地区的六万多人口为例,提出编制小人群寿命表的方法。(1)累计几年的人口数和死亡数,计算该期间的平均寿命。(2)用一年的人口资料计算期望寿命(?)后,对其进行校正。校正方法可用婴儿死亡数的 Poisson 分布的95%上限值,计算婴儿死亡率编制寿命表,计算(?)_0或应用正态分布的原理,计算(?)_0的单侧90%可信限的下限值(?)作为对总体(?)_0的近拟估计。该文还论述了年龄组死亡率为0的估计及人口数与期望寿命方差之间的关系。

How to Make The Life Table in An Small District

A life table in an small district can be made inthe article.Some 60 000 population being used asan example.1.Accumulating the number both of populationand decease in several years then calculating theaverage life of the period.2.Correcting the expectation of life calculatedwith the data of population in one year.Whichcan be done with tow following methods:(1)The 95% upper limit of Poissoin distributionof infant death can be used to calculate infant deathrate then to make life table and get (?).(2)The values of lower limit (?) which one side 90%confident limit calculated with theory of normaldi-stribution can be used as the estimation of the (?).In this article,the estimate of zero for theage special death rate as well as the relaionshipbetween the number of population and the varian-ce of expectation of life.
