The economic slump and the refugee crisis led many Greek millionaires to leave Greece and immigrate to another country, according to the results of an international research, title “Millionaire migration in 2015”, released on Thursday.

Based on the report, 3,000 out of 55,000 millionaires left Greece seeking safer destinations, with most of them choosing UK and US.

However, France topped the list of countries with maximum millionaire outflows as it lost 10,000 millionaires, or 3% of its millionaire population, due to rising tensions in France, especially in Paris following a series of Islamist terrorist attacks in 2015.

The report was compiled by New World Wealth, an agency that gives information on the global wealth sector. It was based on data collected from investor visa programme statistics of each country; annual interviews with around 800 global high net worth individuals and with intermediaries like migration experts, second citizenship platforms, wealth managers and property agents; data from property registers and property sales statistics in each country; and by tracking millionaire movements in the media.
