According to a new study from the Deloitte Center for Financial Services, the total wealth among millionaire households worldwide will more than double in the next decade.
Deloitte estimates that millionaires, who are worth $92 trillion now, will control $202 trillion by 2020.
In the U.S. alone, millionaires will see their wealth surge from $39 trillion to $87 trillion. However, the U.S. share of global millionaire households will grow only 1 percent, to 43 percent.
