Investments controlled by the richest people will rise to $202 trillion

According to the findings of a new survey of millionaires made by Deloitte LLP the number of the richest families will further increase across the globe and especially in the emerging markets. The survey shows that public and private investments controlled by the richest families are expected to more than double in value to $202 trillion by 2020, from $92 trillion this year.

Further the report says that the ranks of households with over a million dollars will rise by two-thirds to 55.5 million in the developed world. They will more than double to 10 million in emerging markets such as China, India and Brazil.

However, Deloitte notes that major part of the world's wealthiest families will continue to be found in the United States and Europe.

Deloitte also says that China, Brazil, Russia and other emerging markets are minting new millionaires at a faster rate than established markets, powered by economic expansion, commodity prices and development.

Across 10 emerging markets, millionaire household wealth is seen tripling to $25 trillion from $7 trillion this year. By 2020 China will likely join the ranks of the top 10 richest economies with $3.6 trillion of wealth.

India's average millionaire would be wealthier than the average American millionaire.
