The dataset includes time series data on the flows of international migrants to and from countries as recorded by 45 countries that gather this information systematically.

The dataset contains annual data on the flows of international migrants as recorded by the countries of destination. The data presents both inflows and outflows according to the place of birth; citizenship or place of previous / next residence both for foreigners and nationals. The current version presents data available from 45 countries.

This compilation of data on international migration flows is useful for analytical purposes; but also serves to raise awareness about the problems of comparability among available statistics. Countries collecting and publishing data on the flows of international migrants use different definitions to identify migrants and use different concepts to determine their origin and destination. The dataset is presented in excel files which; together with a report; are available on CD-ROM.
