Presenting the International Migration Report 2020 on Friday, he said that the US was the top host country for migrants with 51 million of them or 18 per cent of the world's total living there. The report said that between 2000 and 2020, the size of the migrant population abroad grew for nearly all countries and areas of the world with India experiencing the largest gain of nearly 10 million during that period, going from third place in 2000 for the number of migrants to the first spot in 2020.
