Although the globalization of international migration is commonly accepted as a general tendency in contemporary migration patterns (de Haas, Castles, and Miller 2020, 9), the corresponding body of empirical evidence is mixed and fragmented. Our review of global migration patterns over the past half‐century highlights how the theories, expectations, and ultimately findings may vary depending on the specific definitions, vantage points, and measures being used. In this paper, we provide a simpler and integrated account of the globalization of international migration that includes a corresponding empirical template to quantify the relative importance of two processes at work: the intensity and connectivity of international migration. Using recent estimates of country‐to‐country migration flows every five years from 1990–1995 to 2015–2020, our analysis using demographic decomposition and group‐based multitrajectory modeling highlights the dynamic relationship between intensity and connectivity from both the global and country vantage points. Our work in this paper provides a starting point in the form of a much‐needed empirical template, one that is also highly flexible and customizable, for future research on the globalization of international migration to coalesce around and use going forward.

国际移民的全球化？概念和数据驱动的综合


尽管国际移民的全球化被普遍认为是当代移民模式的一般趋势（de Haas、Castles 和 Miller 2020,9），但相应的经验证据是混合和碎片化的。我们对过去半个世纪全球移民模式的回顾强调了理论、预期和最终发现如何根据所使用的具体定义、有利位置和衡量标准而变化。在本文中，我们对国际移民的全球化进行了更简单而全面的解释，其中包括一个相应的实证模板，以量化两个过程的相对重要性：国际移民的强度和连通性。使用从 1990-1995 年到 2015-2020 年每五年对国家间移民流动的最新估计，我们使用人口分解和基于群体的多轨迹建模进行了分析，从全球和国家有利位置突出了强度和连通性之间的动态关系。我们在本文中的工作以急需的经验模板的形式提供了一个起点，该模板也具有高度的灵活性和可定制性，用于未来关于国际移民全球化的研究，以便在未来合并和使用。
