Migration in figures

Estimates vary as to how much money migrants send home, but what is not in dispute is the massive amounts involved and the importance it has for developing economies.

According to the International Labour Organization the money sent back to developing countries is at least $160bn or £82bn, but is likely to be much higher as not all remittances are recorded.

The World Bank estimated in November that the figure for 2006, could be $199bn (£102bn) sent home to developing countries, with $268bn (£137bn) sent home by migrants worldwide.

This money is often greater than the amount developing countries receive in aid, but it comes at a cost as many skilled workers leave their homes in search of higher wages elsewhere.
