Number of World's Billionaires in Sharp Decline

My colleague Deidre Woollard just reported that the number of millionaire households in the U.S. has shrunk to its lowest level since 2003. To that we can now add that the number of billionaires in the world has also seen a steep decline.

According to Forbes' newly-released annual list of the world's billionaires, there are now only 793 billionaires around the globe, down from 1,125 a year ago. That means 332 people lost their billionaire status.

This year the exclusive group has an average net worth of $3 billion, down 23% in 12 months, making for a loss of some $1.4 trillion. Americans now account for 44% of the money and 45% of the list's slots, up 7 and 3 percentage points from last year, respectively. Some billionaires have fared better than others, though most have lost masses of money.

Bill Gates lost $18 billion but regained his title as the world's richest man with a $40 billion fortune. Warren Buffett, last year's No. 1, saw his fortune decline $25 billion as shares of Berkshire Hathaway fell nearly 50% in 12 months, and is in the No. 2 slot with $37 billion. Mexican telecom titan Carlos Slim Helú maintains his spot in the top three but lost $25 billion, and is now worth $35 billion.
