This report sets out to translate migration theory into empirically testable propositions. Drawing actively on elements from different corners of the fragmented landscape of migration theory, the authors (Jørgen Carling, Mathias Czaika and Marta Bivand Erdal) formulate ten propositions, selected based on their relevance to current societal and academic debates on international migration, its dynamics and patterns. The report is a deliverable of the European Union Horizon 2020 Project QuantMig.
