Columbia’s John McArthur says that Dambisa Moyo has claimed that “in the 1970s 10 percent of the population [in Africa] was living in dire poverty. That number is now over 70 percent.” She’s been quoted by Bloomberg as saying that Africa’s “poverty rate doubled between 1981 and 2002.” Niall Ferguson’s foreword to her book says “between 1970 and 1998, when aid flows to Africa were at their peak, the poverty rate in Africa actually rose from 11 per cent to a staggering 66 per cent.” (One review subsequently misquoted this as 1970-78.)
