Asia has more billionaires than any other continent, a survey by a China-based wealth magazine showed on Thursday, overtaking North America for the first time.

There were 1,453 people around the world with a personal wealth of $1 billion or more as of Jan. 17, according to the Hurun Global Rich List for 2013. They had a combined fortune of $5.5 trillion -- the equivalent of China’s GDP.

The average age is 63. One in 10 is female.

Asia is home to the lion’s share of billionaires on the planet with 608 individuals, followed by North America with 440 billionaires and Europe 324.

By country, the U.S. was home to 409 billionaires, comfortably ahead of the 317 from China. Half of all billionaires on the planet live in either the U.S. or China.

Moscow is the billionaire capital of the world, home to 76 billionaires, edging out New York which has 70.  London came in at fifth place behind Hong Kong and Beijing. Five of the top 10 cities for billionaires are in Greater China.

But all these figures are probably under-guesstimates.

“For every billionaire that Hurun Report has found, I estimate we have missed at least two, meaning that today there are probably 4,000 dollar billionaires in the world,” Rupert Hoogewerf, chairman and chief researcher of Hurun Report, said in a statement.

Here’s a look at the world’s top 10 richest man and women:
