According to the annual World Wealth Report from Merill Lynch and Capgemini, the U.S. had 3.1 million millionaires in 2010, up from 2.86 million in 2009. The latest figure tops the pre-crisis peak of three million.

Merrill and Capgemini define millionaires as individuals with $1 million or more in investible assets, not including primary home, collectibles, consumables and consumer durables.

The wealth held by these millionaires also hit a record. North American millionaires had a combined wealth of $11.6 trillion, up from $10.7 trillion in 2009.
