South Africa has seven billionaires, the most on the continent, with Nigeria coming second (four billionaires), but headcount is where South Africa's dominance ends. Nigeria's four billionaires are collectively worth $47.5 billion, $4.5 billion more than South Africa's seven combined.
The average Nigerian billionaire on this list is worth $11.9 billion, nearly double the $6.1 billion average across the border. No other African country threatens either; Egypt's six billionaires share $23.8 billion, and the rest of the continent barely registers.
