India was the leading country of origin of international migrants in 2019 with a 17.5 million strong diaspora, according to new estimates released by the United Nations, which said the number of migrants globally reached an estimated 272 million.

The International Migrant Stock 2019, a dataset released by the Population Division of the UN Department of Economic and Social Affairs (DESA) today, provides the latest estimates of the number of international migrants by age, sex and origin for all countries and areas of the world.

The estimates are based on official national statistics on the foreign-born or the foreign population obtained from population censuses, population registers or nationally representative surveys.
