About the book
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).
