According to the Hurun Report, there are 2,694 billionaires in the world, that is 437 more than the last year.
"A boom in China, a weak dollar and a 26% hike in Nasdaq have led to a surge in dollar billionaires across the world," Rupert Hoogewerf, Hurun Report Chairman, and Chief Researcher.
Four of the top 10 richest self-made women in the world are from China and 28 of the 50 women listed.
