Only 14 self-made women among world's 1,000 billionaires

Seven of the women on the list were Chinese, Harry Potter author JK Rowling was the only British-born woman, and of the fourteen, at least five built their business empires with the help of husbands and brothers or sometimes both.

By contrast, Forbes said that 665 of the world’s 1,011 dollar billionaires, including the three wealthiest men on the planet, Carlos Slim, Bill Gates and Warren Buffett, were self-made men. That, it said, meant that the ‘female billionaires’ club’ accounted for two per cent of the total number of self-made billionaires.
