Hawaii has the nation's largest percentage of households with at least $1 million in investable assets, according to a New York-based market research company.
Phoenix Affluent Marketing Service reports that 6.79 percent of Hawaii's households, or about one out of every 15, had at least $1 million in investable assets in 2006. New Jersey, Maryland, Connecticut and Massachusetts rounded out the top five.
Hawaii also led the list in 2005, with a percentage of 6.01 percent.
"The high cost of living combined with the affluent lifestyle gives Hawaii the edge in ratings," said David M. Thompson, vice president and managing director, affluent practice.
The high cost of real estate also could give the islands an edge. The median price of a single-family home on Oahu last month was $643,500. The national median price of a single-family home was $222,000, according to the National Association of Realtors.
