Over the last two decades both immigration politics and research on immigration issues have become very important. So far; there is however no dataset that would allow researchers to systematically investigate immigration policies across a large sample of countries. The aim of the Immigration Policies in Comparison (IMPIC) project is therefore to provide a set of sophisticated quantitative indices to measure immigration policies in all OECD countries and for the time period 1980-2010. By means of this new dataset the causes and effects of immigration policies will be studied more systematically.
The Immigration Policies in Comparison (IMPIC) project is led by Marc Helbling and was funded by the Emmy-Noether program of the German Research Foundation for the period 2011-2016.
