India saw the fourth-biggest outflow of high net worth individuals globally in 2015 with 4,000 millionaires shifting overseas.
According to a report by New World Wealth, some 4,000 wealthy Indians changed their domicile in 2015, while France saw the maximum outflow of millionaires with as many as 10,000 leaving.
France was followed by China, with 9,000 leaving the country while Italy stood at third with 6,000 exits.
The report said France is being heavily impacted by rising religious tension, especially in urban areas. "We expect that millionaire migration away from France will accelerate as these tensions escalate," it said.
In terms of millionaire inflows, Australia topped the chart with 8,000 shifting base there, followed by the US (7,000) and Canada (5,000) in the second and third place respectively.
"The outflows from India and China are not particularly concerning as these countries are still producing far more new millionaires than they are losing," the report said.
This causes a massive wealth drain in India, media in India reported.
In 2014, it was counted that Mumbai has more billionaires than Tokyo; but going by the rate of wealth drain, very soon we will lose this pride. 
Interestingly, this new report on exodus of the rich perfectly matches with our earlier report on the rich leaving India and choosing another country. Wall Street Journals reported that 43,400 Indian millionaires have left India in the last 10 years; whereas New World Wealth said that in the last 14 years, 61,000 Indian millionaires have ditched their motherland in the last 14 years. 
Why PM Modi’s Make in India and Digital India campaigns are failing to retain their best talent? Should the Government do something else to stop this wealth drain, a commentator asked.
