Remittances are playing an increasingly large role in the economies of many countries. They contribute to economic growth and to the livelihoods of less prosperous people (though generally not the poorest of the poor). According to World Bank estimates, remittances totalled US$414 billion in 2009, of which US$316 billion went to developing countries that involved 192 million migrant workers. For some individual recipient countries, remittances can be as high as a third of their GDP.
Overall global remittances also totaled $583 billion.Some countries, such as India and China, receive tens of billions of US dollars in remittances each year from their expatriates. In 2014, India received an estimated $70 billion and China an estimated $64 billion.
