Replication Data for: A global panel dataset of dyadic dual citizenship acceptance

Dual citizenship provides access to secure legal status and rights in more than one country for an unprecedented number of migrants and their descendants around the world. While this requires the matching of legal regulations between two states, existing studies of dual citizenship typically focus on either migrant origin or destination perspectives. To explore the dyadic nature of this phenomenon we introduce the GLOBALCIT Dyadic Dual Citizenship Acceptance Dataset, covering over 1.8 million directed dyad-year observations measuring the legal rules in place in up to 201 states back to 1960. We identify regulatory trends and present estimates of the number and proportion of global migrants affected by changing policy constellations, as well as variation in acceptance across political regimes. We show that migrants are more likely to acquire destination country citizenship, and thus achieve democratic representation, in constellations where they can maintain a legal link with their origin country.
The GcDDCAD is made available freely for non-commercial use by the general public. Data are not intended to be used for determining citizenship status in individual cases, for which it is recommended to seek professional legal advice.
