A New Agenda for Immigration and Citizenship Policy Research

Given the widespread interest in political solutions to the current problems associated with immigration, we need to have an accurate understanding of existing policies in a cross-national perspective. To explain the coming into being and effectiveness of these policies, researchers have recently started to quantify immigration and citizenship policies and built databases across time and a large number of countries. These indices are likely to reconnect political science research with a field from which it has long been disconnected in terms of theories and methodology—the sub-field of migration and citizenship research. This special issue brings together scholars from North America and Europe who have been at the forefront of index-building and have started to employ these indices in empirical research.
