According to the International Organisation for Migration, current estimates are that there are 244 million international migrants globally (or 3.3% of the world’s population). Work is the major reason that people migrate internationally, and migrant workers constitute a large majority of the world’s international migrants, with most living in high-income countries and many engaged in the service sector.
Global displacement is at a record high, with the number of internally displaced at over 40 million and the number of refugees more than 22 million.
Since 2000, IOM has been producing world migration reports. This World Migration Report 2018, the ninth in the world migration report series is meant to better contribute to increase the understanding of current and strategic migration issues throughout the world.
