India has seen the fourth-biggest outflow of millionaires globally in 2015, according to a report by New World Wealth. Around 4,000 uber-rich Indians have changed their domicile last year, PTI quoted the report as saying. France topped the list, with with as many as 10,000 millionaires leaving the country, followed by China with 9,000 and Italy with 6,000.

The report said that the migration from countries such as India and China was not a concern since "these countries are still producing far more new millionaires than they are losing". It added that "once the standard of living in these countries improves, we expect several wealthy people to move back".

In terms of millionaire inflows, Australia topped the chart with as many as 8,000 uber-rich people moving to the country, followed by the US (7,000) and Canada (5,000). Millionaires, otherwise known as "high net-worth individuals", refer to people with net assets of $1 million or more, excluding their primary residences, said the report.
