The United Nations says there are 100 million people now working outside their home countries. The vast majority have moved from the developing to the developed world. A quarter of all those migrants live in the US, and one-third are in Europe. Migrant workers from developing countries sent home $305 billion in 2008. But they've been hit by the recession. The latest forecasts show remittances this year dropping to as low as $280 billion, a fall of 8.2 per cent. The families of workers from Eastern Europe, Central and East Asia and sub-Saharan Africa will see the biggest falls in remittances. In the first of a series looking at the plight of migrant workers, Al Jazeeras Haru Mutasa met Zimbabweans seeking a better life in South Africa.
