• DEMIG POLICY data

    DEMIG POLICY tracks more than 6,500 migration policy changes enacted by 45 countries around the world mostly in the 1945-2013 period. The policy measures are coded according to the policy area and migrant group targeted, as well as the change in restrictiveness they introduce in the existing legal system. The dataset allows for both quantitative and qualitative research on the long-term evolution and effectiveness of migration policies.

  • DEMIG TOTAL data

    DEMIG TOTAL reports immigration, emigration and net migration flows for up to 161 countries covering various periods of time from the early 1800s to 2011, disaggregating total flows of citizens and foreigners whenever possible. The dataset allows for quantitative analysis of the long-term evolution of international migration.

  • DEMIG C2C data

    The DEMIG C2C (country-to-country) database contains bilateral migration flow data for 34 reporting countries and from up to 236 countries over the 1946–2011 period. It includes data for inflows, outflows and net flows, respectively for citizens, foreigners and/or citizens and foreigners combined, depending on the reporting countries. The DEMIG C2C database was compiled through extensive data collection and digitalisation of historical national statistics as well as current electronic sources. It provides a unique opportunity to construct migration flows from many origin countries to the 34 reporting countries, as well as return flows.
