Asia – home to around 4.6 billion people – was the origin of over 40 per cent of the world’s international migrants in 2019 (111 million). More than half (66 million) were residing in other countries in Asia, a significant increase from 2015, when around 61 million were estimated to be living within the continent. Intraregional migration within Asia has increased significantly over time, rising from 35 million in 1990. Considerable growth has also occurred in Asian-born migrant populations in Northern America and Europe over the last two decades. In 2019, migration from Asia to Northern America reached 17 million, rising from a little over 16 million in 2015, whereas in Europe, migration from Asia stood at nearly 22 million in 2019. Migration from Asia to Northern America and Europe drove much of the increase in the number of Asian migrants outside the region, reaching a total of 44.6 million extra-regional migrants in 2019, an 11 per cent increase from 40 million in 2015.
In 2019, around 7.7 million international migrants from outside Oceania were living in the region. The foreign-born migrant population was primarily composed of people from Asia (49%) and Europe (38%). Throughout the last 30 years, the Asian migrant group has grown, while the number from Europe has remained steady.
