City with the most billionaires is…

The world has at least 1,453 billionaires, with about half of those residing in the U.S. and China, according to the Hurun Global Rich List.

In terms of cities, Moscow is home to the greatest number of billionaires with 76, followed by New York (70), Hong Kong (52), Beijing (41) and London (40).

"For every billionaire that Hurun Report has found, I estimate we have missed at least two, meaning that today there are probably 4,000 billionaires in the world," said Rupert Hoogewerf, chairman and chief researcher of Hurun Report, a Shanghai-based publishing group that tracks China's wealthy.
