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。
This paper takes the population of more than 60,000 in a district of Beijing as an example and proposes a method for preparing a life table for small groups. (1) Accumulate the number of years and the number of deaths, and calculate the average life span of the period. (2) Calculate the expected life (?) using one year’s population data and correct it. The calibration method can use the 95% upper limit of the Poisson distribution of the number of infant deaths, calculate the infant mortality life table, calculate (?)_0 or apply the principle of normal distribution, and calculate the unilateral 90% confidence limit of (?)_0 The lower limit (?) is used as a near-estimate of the overall (?)_0. The article also discusses the relationship between the estimation of mortality in the age group and the relationship between the population and the life expectancy variance.
