In 2016, the figure stood at 6,000, while in 2015 as many as 4,000 millionaires shifted base.
The report, however, noted that the outflows of HNWIs from India and China are not "concerning" as these countries are producing far more new HNWIs than they are losing.
"Also, once the standard of living in these countries improves, we expect several wealthy people to move back," it added.
On the other hand, Australia was the top country for HNWI inflows in 2017 with 10,000 ultra-rich people shifting base to this country, beating out its main rival the US for the third year running.
Over the past 10 years, total wealth held in Australia has risen by 83 per cent compared to 20 per cent growth in the US. As a result, the average Australian is now significantly wealthier than the average US citizen, which was not the case 10 years ago, it added.
The US was the second most popular destination for migrating HNWIs in 2017 at 9,000, followed by Canada (5,000) and United Arab Emirates (5,000).
As per the report, India has been ranked sixth in the list of wealthiest countries with total wealth of USD 8,230 billion.
India is home to 3,30,400 HNWIs (individuals with USD 1 million or more in net assets). Globally, India was ranked 9th in this aspect. The country has 20,730 multi-millionaires, 7th largest in the world.
And in terms of resident billionaires, India with 119 such individuals was named among the top three countries globally, after the US and China.
