BACKGROUND
The life-course perspective has become one of the main paradigms in migration research, providing a rich and fruitful framework for understanding migration behavior. Despite a large literature on the association between internal migration and life-course transitions, little effort has been made to understand the impact of increasing diversity in the life-course trajectory of young adults on heterogeneity in migration behavior.

OBJECTIVE
To address this gap, this paper seeks to establish intra- and inter-cohort variation in the occurrence, order, and timing of reasons for migrating among young adults.

METHODS
We apply sequence and cluster analysis to self-reported reasons for migrating collected from 2002 to 2019 as part of the Household Income and Labour Dynamics in Australia (HILDA) survey and follow two cohorts of young adults born between 1982–1984 and 1990–1992 over 10 years. We distinguish between education, employment, family, housing, amenity, lifestyle, and health migration.

RESULTS
Sequence analysis reveals diversity in individual migration trajectories, shaped by the number and timing of migrations and the type of reason. Intra-cohort variation is manifested by the delineation of five distinct migration clusters, while inter-cohort change is most visible in the growing share of young adults that follow diverse and delayed migration trajectories.

CONCLUSIONS
Sequence analysis is a promising tool to advance understanding of migration behavior, which can now find greater usage thanks to the maturation of longitudinal surveys.

内部迁移和生命过程的去标准化：迁移原因的序列分析（作者：Aude Bernard，Sunganani Kalemba）

背景
生命历程视角已成为移民研究的主要范式之一，为理解移民行为提供了丰富而富有成果的框架。尽管有大量关于内部迁移与生命历程转变之间关联的文献，但很少有人努力了解年轻人生命历程轨迹中日益多样化对迁移行为异质性的影响。

目的
为了解决这一差距，本文试图确定年轻人迁移原因的发生、顺序和时间的队列内和队列间差异。

方法
作为澳大利亚家庭收入和劳动力动态 (HILDA) 调查的一部分，我们将序列和聚类分析应用于 2002 年至 2019 年收集的自我报告的迁移原因，并跟踪了 1982-1984 年和 1990-1992 年间出生的两个年轻人群10年。我们区分教育、就业、家庭、住房、便利设施、生活方式和健康移民。

结果
序列分析揭示了个体迁移轨迹的多样性，由迁移的数量和时间以及原因类型决定。群组内的变化表现为五个不同的迁移集群的描绘，而群组间的变化在遵循多样化和延迟迁移轨迹的年轻人中越来越明显。

结论
序列分析是一种有前途的工具，可以促进对迁移行为的理解，由于纵向调查的成熟，现在可以找到更多的用途。
