„Young people make up the bulk of the international migrant flow – around 70 per cent of them is younger than 30. In terms of stock, young people aged 15–29 accounted for 21.2 per cent of the 244 million international migrants worldwide in 2015. This translated to over 51 million international migrants aged 15–29 years – more than half of them aged 15–24.“
