In addition, the number of millionaires in US dollars, which the report described as "high net worth individuals (HNWI)" increased 21.5 percent in Sweden last year, compared with 12.5 percent in Europe and 17.1 percent for global growth.
"The Swedes have a relatively high proportion of equities in their portfolios and growth on the Stockholm Stock Exchange was stronger than on the stock exchanges in many other countries," said Robin Segerfeldt, head of asset management at Capgemini.
"In Europe, it is more common with a higher proportion of fixed-income securities and a lower proportion of equities."
In 2009, the number of dollar millionaires increased around the world to 10 million people. Accordingly, the record-setting decline in 2008 has nearly recovered.
The majority of dollar millionaires continue to come from the US, with 3.1 million people. The US, Japan and Germany are home to 53.5 percent of the millionaires, a slight decrease from the 2008 share of 54 percent.
