Rising global commodities prices and Asia’s economic boom led to a big increase in the number of billionaires in Russia, China and Brazil in 2011.

China nearly doubled its number of billionaires to 115, while Russia and Brazil posted two-third jumps to 101 and 30, respectively, Forbes said in its annual list of the world’s richest people.

It was the first time any country outside the United States, which has 413 billionaires, had more than 100. Moscow is now home to the most people on the list with 79 billionaires, easily outstripping New York, which has just 58. The world’s richest man, Mexican tycoon Carlos Slim, retained his crown for the second year in a row and made more money than any of the other 1,209 billionaires in the past year: $20.5 billion, taking his fortune to $74 billion.
