Europe hosts the largest number of international migrants, at 82 million; followed by North America, at 59 million; with 51 million in the United States alone - the largest number in a single nation. Finally, North Africa and Western Asia host around 49 million migrants, and along with sub-Saharan Africa, are seeing the most significant influx in foreign populations.
The share of international migrants in the total population varies considerably across regions, the report shows, where foreign-born individuals comprise 21 per cent of the population of the Oceana region (Australia and New Zealand included), and 16 per cent of all people in Northern America.
With forced displacements continuing to increase, refugees and asylum seekers account for close to a quarter of global increases, which have risen by 13 million in number from 2010 to 2017.
Although migration is global, most journeys are taking place within a limited set of countries, with the US, Germany, and Saudi Arabia making up the top three.
The link between migration and development is very well established, Director for DESA's Population Division, John Wilmoth told reporters at the UN, echoing the message from the Department's Under-Secretary General ahead of the report release.
The data are critical, Llu Zhenmin said, for understanding the important role of migrants and migration in the development of both countries of origin and destination.
Facilitating orderly, safe, regular and responsible migration and mobility of people will contribute much to achieving the Sustainable development Goals, he urged.
Mr. Wilmoth said as a general observation, the contribution of migrants both in host countries and countries of origin, includes sending valuable remittances back to countries of origin, and a major social contribution through transmission of ideas.
The United Nations is committed to supporting safe migration, through international agreements to safeguard refugees and people on the move at large. The Global Compact on Refugees, and Global Compact for Safe, Orderly and Regular Migration, were adopted in December of last year. DESA's full 2019 migration data set, available here.
