Over 30 million Africans live in the diaspora. They sent almost $40bn home in 2014, a figure that is likely to grow significantly in the coming years. While north African countries such as Morocco, Algeria and Egypt receive the most, east African countries are particularly dependent on remittances.
The average per migrant is almost $1,200, representing 5% of GDP on a country-by-country average. Yet the cost of sending money is high.
