It seems like the recessions have almost negligible effects on the millionaire families. The Deloitte Center for Financial Services forecasted that by 2020, the total families with net worth of $1 million will double.

It has been found by the survey that U. S. and European countries have a greater accumulation of wealth than other parts of the globe. This gap is being narrowed down by the developing countries but still U. S. and Europe are outpacing the others in terms of wealth.

On the other hand, China will be leading the millionaire family by 2020. This will be followed by Brazil and Russia. China and South Korea will be placed in the top 10 countries with maximum millionaire.

"There is going to be very fast growth, but it will take a lot longer to reach anything like the wealth in the developed world," noted Andrew Freeman, Executive Director of the Deloitte Centre for Financial Services and lead author of the report.

By 2020, it is expected that there will be 43% rise in the wealth in U. S.

Japan will have 8.6 million millionaire families in the country by 2020. Japan will have 9% of the world’s wealth.
