摘要

背景人口老龄化是人口结构转型的一个基本因素。在没有出生、死亡和移民的情况下，任何人口的平均年龄每年都会增加一年。时期出生、死亡和迁移条件的强度（即其粗略比率以及其平均年龄与人口平均年龄之间的差异）要么减少要么加强了人口老龄化的自然趋势。目的研究1950年至2100年全球出生、死亡和移民对人口老龄化的影响。我们研究了人口老龄化的协同模式是否与时期人口状况的变化有关。

World population aging as a function of period demographic conditions

BACKGROUND Population aging is a fundamental element of the demographic transition. In the absence of births, deaths, and migration, the mean age of any population will increase one year per calendar year. The intensity of period birth, death, and migration conditions (i.e., their crude rates and the difference between their mean age and the mean age of the population) either lessen or strengthen this natural tendency of populations to age. OBJECTIVE We investigate the contribution of births, deaths, and migration to population aging across the globe from 1950 to 2100. We examine whether a concerted pattern of population aging is associated with changes in period demographic conditions.
