The relationship between internal and international migration has traditionally been overlooked in migration research. Seeking to bridge this divide, we examine the cumulative, socioeconomically selective and functionally differentiated nature of youth spatial mobility. Using harmonized microdata from two nationally representative surveys of bachelor's graduates and advanced vocational trainees from the 2013/2014 cohort, we examine the role of pre‐graduation mobility, social origin and field of study in shaping postgraduation migration outcomes. Our findings show that any form of educational mobility is a strong predictor of subsequent migration. Migration trajectories are also stratified by parental education, with graduates from more privileged backgrounds more likely to engage in international or complex mobility paths. Additionally, migration motives and patterns vary by migration type and field of study, supporting a functional differentiation between internal and international mobility. These results highlight how different forms of mobility are embedded in cumulative life‐course processes and socially structured opportunity regimes, underscoring the need for more integrated theoretical and policy approaches to youth migration.

从学生到搬家者：将西班牙本科生和高级职业培训毕业生的国内和国际移民轨迹联系起来

国内移民和国际移民之间的关系历来在移民研究中被忽视。为了弥合这一鸿沟，我们研究了青年空间流动性的累积性、社会经济选择性和功能差异化性质。使用来自 2013/2014 年度学士毕业生和高级职业培训生的两项具有全国代表性的调查的统一微观数据，我们研究了毕业前流动性、社会出身和研究领域在塑造毕业后移民结果中的作用。我们的研究结果表明，任何形式的教育流动性都是后续迁移的有力预测因素。移民轨迹也按父母的教育程度分层，来自更优越背景的毕业生更有可能参与国际或复杂的流动道路。此外，移民动机和模式因移民类型和研究领域而异，这支持了国内和国际流动性之间的功能区分。这些结果突出了不同形式的流动性如何嵌入累积的生命历程过程和社会结构的机会制度中，强调了对青年移民采取更综合的理论和政策方法的必要性。
