"The MIPEX includes 31 countries in order to provide a view of integration policies across a broad range of differing environments.
For a long time North America was cited as the continent of immigration, while Europe was largely a continent of emigration. Some European countries still are (including many in Central Europe and the Baltics). Now a great many European countries are established countries of immigration (Nordic countries, Western Europe, Southern Europe), where every year many people come into the country, often more than leave.
For some countries, immigration is a very recent phenomenon (including Southern Europe, Czech Republic, Finland and Ireland), while many attract migrant workers."
