This report presents information on levels and trends in international migration for major areas, regions and countries of the world, and on the ratification status of migration-related legal instruments. The data for the international migrant stock described in chapter I are taken from the publication Trends in International Migrant Stock: The 2015 Revision, while the estimates on the total population in chapter I are based on World Population Prospects: The 2015 Revision, DVD Edition. The estimates on net migration and the projected population up to 2050 presented in chapter II are based on World Population Prospects: The 2015 Revision, DVD Edition. Chapter III provides an analysis of the status of ratification (by Member States) of the migration-related legal instruments of the United Nations and the International Labour Organization (ILO), based on information from the United Nations Treaty Section (http://treaties.un.org) and the NORMLEX Information System on International Labour Standards (http://www.ilo.org).



Net international migration

From 1950 to 2015, the developed regions gained population due to positive net migration while the developing regions lost population as a result of negative net migration. Between 1950 and 2010, the magnitude of the net inflow of migrants to the developed regions increased steadily, reaching an average of 3.2 million per year between 2000 and 2010, up from less than 0.3 million per annum from 1950 to 1970. After 2010, however, the size of the net inflow of persons to the developed regions declined for the first time in five decades, falling to 2.3 million per year between 2010 and 2015.
