Migration Studies: Data & Statistics

CESSDA Training Group's webinar introduces information on how to find and access data from European social science data archives.

Landscan Global Population Database

A population database that maps geographical distribution of a populace within cells of one-kilometre resolution over a 24 hour period. This allows assessment, estimation & visualisation of populations reacting to disease outbreaks, social upheaval or natural disasters. The modelling process uses sub-national level census counts and other data for each country combined with high resolution imagery analysis.

IMI Migration datasets

The International Migration Institute (IMI) collected primary data and compiled existing macro-data from archives and electronic sources, and has made several of the resulting datasets freely available.

DEMIG (Determinants of International Migration)

IMI's five-year programme (2010–2014), funded by the European Research Council, has compiled new migration flow, policy and visa databases, and generated a series of theoretical and empirical research papers.

DEMIG policy data

tracks more than 6,500 migration policy changes enacted by 45 countries around the world mostly in the 1945-2013 period.


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.

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.


Imagining Europe from the Outside investigated the impact of perceptions of human rights and democracy on migration aspirations and decisions.


‚ÄčTHEMIS data

Theorising the Evolution of European Migration Systems was a four-year project which took a fresh look at how patterns of migration to Europe develop.
