年龄别死亡率概括指标大致可分为两大类:一类是集合指标,例如直接法标准化死亡率,两个人口比较时,反映相应年龄组死亡率的绝对差;另一类是相对指标平均数,反映两个人口相应年龄组死亡率的比差。本文以年龄别死亡率几何均数作为年龄别死亡率的一个概括指标,优点是直观简单、易计算、不需要标准人口、不同人口可直接比较,并可反映年龄别死亡率的指数类型。
Summary of age-specific mortality can be broadly divided into two broad categories: one is set of indicators, such as the direct method of standardized mortality, the two population comparison, reflecting the absolute difference in mortality of the corresponding age group; the other is the relative index of the average Number, reflecting the ratio of mortality between the two population corresponding age group. In this paper, the geometric mean of age-specific mortality is taken as a general indicator of age-specific mortality. The advantage of this paper is that it is intuitive and easy to calculate, does not require a standard population, and can be directly compared among different populations and reflects the index type of age-specific mortality.
