An enormous number of people are leaving their homelands around the world today. This has happened several times in the past, but migration has spiked in recent years. These population movements can have significant effects on both the host country (where emigrants or refugees settle), as well as politics back in the homeland. After they leave their homelands, why do some groups mobilize, and in what ways? In this article, we examine a number of factors that may impact when emigrated groups mobilize after they move. We develop a new dataset on potential diasporas in the United States to evaluate a series of hypotheses; including those about motivations for mobilization such as identity maintenance, the objective plight of co-ethnics in the homeland, and group capacity to mobilize. We find some merit in the identity preservation argument and a strong effect of geographic concentration of the diaspora segment. Surprisingly, diaspora mobilization does not appear to be strongly related to conflict in the homeland among these groups.

今天，无数人正在离开他们的家园。过去曾发生过几次，但近年来移民猛增。这些人口流动可能对东道国（移民或难民定居的地方）以及祖国的政治产生重大影响。他们离开家园后，为什么有些人动员起来，以什么方式动员？在本文中，我们研究了许多因素，这些因素可能在移居群体移居后动员时产生影响。我们针对美国的潜在散居者开发了一个新的数据集，以评估一系列假设。包括与动员动机有关的动因，例如身份认同维护，祖国同族人的客观困境以及团体动员的能力。我们在身份保存论据中发现了一些优点，并发现了散居人群地理集中的强烈影响。出人意料的是，散居侨民的动员似乎与这些群体之间的家园冲突没有密切关系。
