Main limitations of DEMIG POLICY
- The focus of DEMIG POLICY was the post-1945 period, therefore historical policy changes are less comprehensively tracked.
- The focus of DEMIG POLICY was national policy making, therefore supra-national policies such as bilateral agreements are not comprehensively recorded (with the exception of post-WWII recruitment agreements) and sub-national policies are not tracked at all.
- The focus of DEMIG POLICY on migration policy change is due to its underlying aim to analyze the evolution and effectiveness of migration policies. DEMIG POLICY allows performing cross-country comparisons of the change in migration policy restrictiveness over time. It does however not allow comparing absolute levels of migration policy restrictiveness between countries at a given point in time.
