ABS - Life Tables - Life Expectancy (SA4) 2010-2019

This dataset presents life expectancy at birth estimates for males, females and persons. This dataset covers the reference period 2010-12 to 2017-19, and is based on Statistical Area Level 4 (SA4), according to the 2016 edition of the Australian Statistical Geography Standard (ASGS).\n\nFor further information please visit the [Australian Bureau of Statistics](https://www.abs.gov.au/statistics/people/population/life-tables/2017-2019).\n\n Internationally, life tables are used to measure mortality. In its simplest form, a life table is generated from age-specific death rates and the resulting values are used to measure mortality, survivorship and life expectancy. The life table depicts the mortality experience of a hypothetical group of newborn babies throughout their entire lifetime. It is based on the assumption that this group is subject to the age-specific mortality rates of the reference period. Typically this hypothetical group is 100,000 persons in size.\n\n AURIN has spatially enabled the [original data](https://www.abs.gov.au/statistics/people/population/life-tables/latest-release#data-download).

本数据集提供了男性、女性及全体人口的出生预期寿命估算值。本数据集的参考时段为2010-12至2017-19，其地理分区依据《澳大利亚统计地理标准（2016版）》（Australian Statistical Geography Standard, ASGS）中的4级统计区域（Statistical Area Level 4, SA4）划定。

在国际学界，生命表（life table）常被用于衡量死亡水平。最简形式的生命表由分年龄死亡率生成，其计算结果可用于表征死亡水平、存活概率与预期寿命。生命表描述了一组假想新生儿群体在完整生命周期内的死亡历程，其构建前提为：该假想群体遵循参考时段的分年龄死亡率。此类假想群体的初始规模通常设定为10万人。
