Replication Data for: The international diffusion of expatriate dual citizenship

Replication data for The international diffusion of expatriate dual citizenship, published in Migration Studies (2019) by Maarten Vink, Arjan H. Schakel, David Reichel, Ngo Chun Luk and Gerard-Rene de Groot. Abstract: While the global increase of expatriate dual citizenship acceptance over the past decades has been widely observed, the temporal and spatial contexts of this trend have remained understudied. Based on a novel dataset of expatriate dual citizenship policies worldwide since 1960 we find that dual citizenship toleration has increased in the last half century from one-third to three-quarter of states globally. We argue that these domestic policy changes should be understood in light of normative pressure in a world where restrictions on individual choice in citizenship status are increasingly contested and where liberalisation is reinforced through interdependence and diaspora politics. We apply Cox proportional hazard models to examine dual citizenship liberalisation and find that states are more likely to move to a tolerant policy if neighbouring states have done so and that they tend do so in conjunction with extending voting rights to citizens residing abroad and receiving remittances from abroad. Contrary to other studies we do not observe significant variation by regime type.
