There were 29 African billionaires in 2014, up from 20 just 2 years ago. In the same year, there were six newcomers to Forbes' annual ranking of Africa's richest. At the other end of the spectrum, seven people had dropped off the list, including SA's Cyril Ramaphosa, Adrian Gore and Raymond Ackerman. The 10 richest, however, have managed to remain steadfast.

For the first time in the four years that Forbes has been tracking Africa’s richest, Nigeria bested South Africa. At the top yet again was (is) cement tycoon Aliko Dangote of Nigeria, joined on the list of 'Africa’s 50 Richest' by 12 other countrymen. In comparison South Africa claims 11 spots, down from 14 a year ago.
