The IOM's World Migration Report 2020 surveyed trends in international migration, noting that UN's DESA estimated there were 272 million international migrants in 2019, up from 221 million in 2010. The number of international migrants has tripled since 1970, and the migrant share of the world's population rose from 2.3 percent to 3.5 percent of the world's 7.7 billion people in 2019.
Asia (84 million) and Europe (82 million) have over 60 percent of the world's migrants; migrants are a much larger share of Europe's 740 million people, 11 percent, than they are of Asia's 4.6 billion, 1.8 percent. Migrant shares were highest in Oceania, where eight million migrants among 38 million people made migrants 21 percent of residents, and North America (Canada and US), where 59 million migrants among 370 million people made migrants 16 percent of residents.
