"Estimates [for the period 1970-2008] show that over the 39-year period Africa lost an astonishing US$854 billion in cumulative capital flight--enough to not only wipe out the region's total external debt outstanding of around US$250 billion (at end-December, 2008) but potentially leave US$600 billion for poverty alleviation and economic growth. Instead, cumulative illicit flows from the continent increased from about US$57 billion in the decade of the 1970s to US$437 billion over the nine years 2000-2008." - report by Global Financial Integrity.
