About
The International Migration Policy And Law Analysis (IMPALA) Database is a cross-national, cross-institutional, cross-disciplinary project on comparative immigration policy.
The database, which will be used for both qualitative and quantitative research across a range of disciplines, improves existing databases on policy and captures trends in immigration selection policy, naturalization policy, illegal immigration policy and bilateral agreements across 20 OECD countries, across time.
It opens up possibilities for a range of comparative qualitative and quantitative research on the determinants of migration policy and the effect of migration policy on social, economic, demographic and political trends.
It is the product of an international collaboration between researchers from George Mason University, Harvard University, London School of Economics and Political Science, Paris School of Economics, University of Amsterdam, University of Luxembourg, and University of Sydney.
Pilot data covers 10 years and 9 country cases including Australia, France, Germany, Luxembourg, Netherlands, Spain, Switzerland, United Kingdom, and the United States of America. Please sign up if you would like to be notified by email when these data become publicly available.
