New Delhi, A study has estimated that about 19 million people, averaging 1.35 million per year, have migrated from India, Pakistan, and Bangladesh to Saudi Arabia, Qatar, Bahrain, and the United Arab Emirates since 2010.
The data compares to 13.6 million movements from Mexico to the US over the entire period since 1990, researchers from the London School of Economics and Political Science (LSE), International Institute for Applied Systems Analysis in Austria and the University of Hong Kong said.
