寿命表(亦称生命表)是根据一定地区一定时间阶段人群的性别、年龄别死亡率计算出来的一种统计表。原理是假定有同时出生的“一代人”,按照特定的年龄别死亡率(应变换为死亡概率)先后死去,直到死完为止,通过一系列指标的计算,可以了解这“一代人”一共活了多少岁,平均可活多少岁,活到某一年龄时尚存多少人,已经活到某一年龄的人平均还可活多少岁,从而表现出这“一代人”的死亡规律与生存规律。寿命表广泛应用于表示居民健康水平与特征,研究人口自然变动问题;其衍生的统计方法,应用尤广。
Life table (also known as the life table) is based on a certain period of time in certain areas of the population sex, age-specific mortality calculated as a table. The principle is to assume that there are “one generation” born at the same time and that they die in accordance with a specific age-specific death rate (which should be converted to the death probability) until they are finished. Through a series of calculation of indicators, one can understand that this “generation” How old are they? How many people live on average? How many people live to a certain age? How many people have lived to a certain age on average? The life table is widely used to represent the residents’ health level and characteristics and to study the natural population changes. The derived statistical methods are widely used.
