The International Organization for Migration (IOM) is part of the United Nations System as the leading inter-governmental organization promoting since 1951 humane and orderly migration for the benefit of all, with 174 member states and a presence in over 100 countries.
Education is another reason for international migration, as students pursue their studies abroad, although this migration is sometimes temporary, with a return to the home country after the studies are completed. These migrants can also be divided into two large groups, permanent and temporary.
WORLD MIGRATION REPORT 2020 31 Migration flows There are currently two main international datasets on international migration flows, both of which are derived from national statistics: UN DESA’s International Migration Flows dataset and OECD’s International Migration Database.
For statistical purposes, the United Nations defines an international migrant as any person who has changed his or her country of residence. This includes all migrants, regardless of their legal status, or the nature, or motive of their movement.
