The survey, conducted by the UN Department of Economic and Social Affairs (DESA), found that around 15.5 million Indians live outside the country, forming the world’s largest Diaspora. Since 2005, when Indians formed the world’s third largest Diaspora at 9.5 million, their numbers have risen by staggering 60%, the UN report stated.
The DESA report also found around 225 million people lived as international migrants, or in a country other to the one they were born in, in 2015 – an over 40% increase from 2000. Twenty million of these migrants are refugees, the survey found.
The UN data also revealed the number of international migrants has grown faster than the world's population, with the share of migrants in the global population reaching 3.3% in 2015.
“What I found particularly interesting is how important migration has been for population growth, which is sorely needed in certain parts of the world,” said Jan Eliasson, the deputy secretary-general of the United Nations.
