This year, however, it’s no longer Bill Gates. Mexican communication tycoon Carlos Slim Helu has taken the top spot with $53.5 billion. The United States still has the most billionaires on the list, but that number has slipped as well.

From Forbes:

This year the World’s Billionaires have an average net worth of $3.5 billion, up $500 million in 12 months. The world has 1,011 10-figure titans, up from 793 a year ago but still shy of the record 1,125 in 2008. Of those billionaires on last year’s list, only 12% saw their fortunes decline.

U.S. billionaires still dominate the ranks–but their grip is slipping. Americans account for 40% of the world’s billionaires, down from 45% a year ago.

The U.S. commands 38% of the collective $3.6 trillion net worth of the world’s richest, down from 44% a year ago.

Of the 97 new members of the list, only 16% are from the U.S. By contrast, Asia made big gains. The region added 104 moguls and now has just 14 fewer than Europe, thanks to several large public offerings and swelling stock markets.
