India top country of origin of international migrants: Pew

Ahead of the International Migrants Day, Pew Research said as of 2015, nearly 3.5 million Indians lived in the UAE, the world's second-largest migration corridor.

Unlike the Mexico-US corridor, the number of Indians living in the UAE and other Persian Gulf countries has increased substantially during the past decade, from 2 million in 1990 to more than eight million in 2015, Pew said.

"Most have migrated for economic opportunities in these oil-rich countries," it added.

Authored by Philip Connor, the report said if all of the world’s international migrants (people living in a country that is different from their country or territory of birth) lived in a single country, it would be the world's fifth largest, with around 244 million people.

"Overall, international migrants make up 3.3 per cent of the world's population today," it said.

The top origins of international migrants are India (15.6 million), followed by Mexico (12.3 million), Russia (10.6 million), China (9.5 million) and Bangladesh (7.2 million).

Among destination countries, the US has more international migrants than any other country.

It is home to about one-in-five international migrants (46.6 million), it said.

Other top destinations of migrants include Germany (12.0 million), Russia (11.6 million), Saudi Arabia (10.2 million) and the United Kingdom (8.5 million), Pew said.
