2012 (952)
The wealth of the top 10 grew $250 million a day in 2012.
The Unites States has 408 billionaires and China, says Hurun, ranks second with 317
But Rupert Hoogewerf, chairman and chief researcher of The Hurun Report, said the 1,453 billionaires is probably an under-guesstimate. He said the real number is probably three times that.
"For every billionaire that Hurun Report has found, I estimate we have missed at least two," he said, "meaning that today there are probably 4,000 dollar billionaires in the world."
