Migration has major impacts on both the people and the places involved in it. When supported by appropriate policies, migration can contribute to inclusive and sustainable development in both origin and destination countries, while also benefitting migrants and their families.

Reliable data on migrants and migration are crucial for assessing current and future trends, identifying policy priorities, and making informed decisions. Reliable data on migration can help ensure that discussions on migration, at both national and international levels, are based on facts, not myths or misperceptions.

The International Migration 2019 report by UN DESA’s Population Division examines the latest migration levels and trends by geographic, development and income grouping, based on the 2019 revision of the International Migrant Stock, which found that the number of international migrants globally reached an estimated 272 million in 2019.

Germany and Saudi Arabia host the second and third largest numbers of migrants (13 million each), followed by the Russian Federation (12 million), the United Kingdom (10 million), the United Arab Emirates (9 million), France, Canada and Australia (around 8 million each) and Italy (6 million).

Migrants from Mexico constituted the second largest “diaspora” (12 million), followed by China (11 million), the Russian Federation (10 million) and the Syrian Arab Republic (8 million).
