According to the latest United Nations estimates, 244 million people, or 3.3 percent of the world’s population, live in a country other than the one where they were born. And among these migrants, Indians make up the largest diaspora: 16 million Indians are scattered across the world.

According to the report that was first published in The New York Times, the most popular destination in 2015 was the United States, followed by Germany, Russia and Saudi Arabia. Does Saudi Arabia surprise you? Well, Saudi Arabia shows up because it hosts an enormous number of migrant workers, not immigrants who resettle, as in the United States.
It is worth nothing that the United Nations report does not distinguish between who migrates with legal papers and who does not.
Among the migrants worldwide are 20 million refugees — those who have fled war or persecution in their home countries.
After India, Mexico has the second largest diaspora, with 12 million living abroad, the majority of them in the United States.
