ABSTRACT

Internal and international migration form part of the same continuum of population movement but are typically conceptualised, measured and studied separately. Despite early theoretical attempts at conceptualising internal and international migration jointly, existing evidence remains partial and fragmented, reflecting a diversity of traditions in migration research. To address this gap in knowledge, this paper takes a step towards integration by comparing the triggers, constraints and resources that shape internal and international migration decisions at the micro-level. To accomplish this, we analyse retrospective migration histories from a 13-country cross-national dataset (the Survey of Health, Ageing and Retirement in Europe, n = 201,061 person-years from 6,112 individuals) using multinomial random-effect logistic regression models that account for duration dependence. The results show that internal and international migration are linked to the same life-course events, although economic-related transitions are more strongly associated with international than internal migration. We also find that the same resources (e.g. education) and constraints (e.g. homeownership) shape internal and international migration decisions. Altogether, our findings suggest that there is an opportunity for greater theoretical cross-fertilisation between internal and international migration.

摘要

内部和国际移徙构成了人口流动同一连续统一体的一部分，但通常分别进行概念化，衡量和研究。尽管早期在理论上尝试将内部和国际移民概念化，但现有证据仍然是零散的和零散的，反映了移民研究的传统多样性。为了解决这一知识鸿沟，本文通过在微观层面比较塑造内部和国际移民决策的触发因素，制约因素和资源，迈出了迈向融合的一步。为此，我们分析了13个国家/地区的跨国数据集的回顾性移民历史（欧洲健康，老龄化和退休调查，n = 6,112人的201,061人年-（1）使用考虑了持续时间依赖性的多项随机效应逻辑回归模型。结果表明，内部和国际移徙与同一人生历程相关，尽管与经济相关的过渡与国际移徙比内部移徙更为密切。我们还发现，相同的资源（例如教育）和约束条件（例如房屋所有权）影响着内部和国际移民决策。总而言之，我们的发现表明，有机会在内部和国际移民之间进行更大的理论交叉交流。
