摘要

委内瑞拉人口外流是拉丁美洲近代史上已知的最大规模的人口迁移。委内瑞拉大规模移民引发的地区危机推动了多个机构间倡议(如 R4V 平台)的发展,也推动了学术界追踪人口外流强度的尝试。然而,人们对移民的年龄和性别构成知之甚少,因为迄今为止,大多数现有文献主要关注的是移民外流的总量和特定国家所占的比例。本研究探讨了近期委内瑞拉人口外流的人口结构、相关变化的时间顺序以及对留在该国的人口的影响。通过对七个主要目的地的委内瑞拉出生人口进行官方统计,估算出 2011 年至 2021 年按年龄和性别划分的年度外流人口数量。利用罗杰斯-卡斯特罗模型的参数,特别是儿童对劳动力的主导作用,并通过分解年龄对年度移民总生产率的贡献,对移民人口构成的变化进行了追踪。在危机的早期阶段(2014-2017 年),移民潮的儿童抚养比很高。随着危机进入最严重阶段(2019 年达到顶峰),移民的平均年龄增加。向外移民导致目前委内瑞拉人口中育龄妇女减少了 20%,劳动适龄人口减少了 17.8%。因此,60 岁或 60 岁以上人口的比例有所增加。

The Demography of Crisis‐Driven Outflows from Venezuela
The Venezuelan exodus represents the largest known displacement of people in recent Latin American history. The regional crisis caused by this mass Venezuelan migration drove the development of multiple interagency initiatives (such as the R4V platform) as well as academic attempts to keep track of outflow intensity. However, little is known about the age and gender composition of the emigrants since most existing literature to date has focused primarily on total volume and country‐specific shares of migration outflows. This study examines the demographics of recent outflows from Venezuela, the chronology of associated changes, and the demographic implications for those remaining in the country. Official counts of Venezuelan‐born populations compiled in seven main destinations are used to estimate annual outflows by age and gender from 2011 to 2021. Changes in the demographic composition of emigration are traced using parameters of the Rogers–Castro model, specifically the children‐to‐labor force dominance, and by decomposing the age contributions to the annual gross migraproduction rate. In the early phase of the crisis (2014–2017), emigration flows had high child dependency ratios. As the crisis entered its most acute phase (peaking in 2019), the mean age of migrants increased. Outward migration has resulted in the current Venezuelan population having 20 percent fewer women of reproductive age and 17.8 percent fewer individuals of working age. Consequently, the share of the population aged 60 or older has increased.

期刊介绍: Population and Development Review is essential reading to keep abreast of population studies, research on the interrelationships between population and socioeconomic change, and related thinking on public policy. Its interests span both developed and developing countries, theoretical advances as well as empirical analyses and case studies, a broad range of disciplinary approaches, and concern with historical as well as present-day problems.
