Noting that the number of international migrants is expected to surpass 250 million this year, an all-time high, as people search for economic opportunity, the Migration and Remittances Factbook 2016 said the fast growing developing countries have increasingly become a strong magnet for people from other parts of the developing world.
International migrants will send US$601 billion to their families in their home countries this year, with developing countries receiving US$441 billion, the report produced by the World Bank Group's Global Knowledge Partnership on Migration and Development (KNOMAD) initiative said.
"At more than three times the size of development aid, international migrants' remittances provide a lifeline for millions of households in developing countries. In addition, migrants hold more than US$500 billion in annual savings," it said.
"Together, remittances and migrant savings offer a substantial source of financing for development projects that can improve lives and livelihoods in developing countries," said Dilip Ratha, co-author of the Factbook.
The top 10 migrant destination countries are the US, Saudi Arabia, Germany, Russia, the UAE, UK, France, Canada, Spain and Australia.

"There is ample research to demonstrate that migration, both of highly-skilled and low skilled workers, generates numerous benefits for receiving and sending countries. The diaspora of developing countries and return migration can be a source of capital, trade, investment, knowledge, and technology transfers," said Sonia Plaza, co-author of the Factbook.
