Kenyans in the diaspora are contributing an equivalent of 3.8 per cent of national income through remittances. In the year 2004, for instance, Kenyans living and working abroad remitted about Ksh35 billion ($464 million), which overshadows the net foreign direct investment (FDI) of Ksh3.6 billion ($50.4 million), which accounted for 0.41 per cent of the country's gross domestic product. "Migration is an important issue in Kenya, with the country both a significant destination and a source of migrants," said Francis Mwega of the Department of Economics at the University of Nairobi during the launch of the World Bank's 2006 Global Economic Prospects report in Nairobi.
