In 2019, the number of international migrants reached 272 million; 33 million of them were children

Among the world’s migrants are nearly 29 million refugees and asylum seekers who have been forcibly displaced from their own countries. An additional 41 million people in 2018 were internally displaced due to conflict and violence, an estimated 17 million of whom were children. The share of the international migrant stock as part of the total population, which had remained around three per cent between 1990 and 2010, has risen to 3.5 per cent by 2019. Together with the rising global population, this has contributed to the 78 per cent increase of the international migrant population globally from 153 million in 1990 to 272 million in 2019. Similarly, the number of migrant children increased from 24 million during the period 1990–2000 to 33 million in 2019.
