The wealthy elite of Fairfield County are not a threat to unseat Bill Gates as the nation's richest individual, but Forbes magazine's new list of the 400 Richest People in America reveals that the county -- and Greenwich in particular -- has a near monopoly on uber-wealth in the state.

While Gates, the founder of Microsoft Corp. from Medina, Wash., placed first in the overall list yet again with a net worth of $59 billion, 11 Connecticut residents are among the rankings -- and eight of them reside in Greenwich.

Only Karen Pritzker, a Branford resident who ranks 273 with a net worth of $1.6 billion garnered through her investments and involvement in the hotel industry, lives outside Fairfield County.

Topping the list in Connecticut is Steve Cohen, founder and manager of SAC Capital Advisors, a hedge fund with $16.6 billion in assets. Ranked 35th overall, Cohen's net worth is listed at $8.3 billion.

Not far behind at No. 44 with $6.5 billion is Ray Dalio, founder of Bridgewater Associates, considered the world's biggest hedge fund.

The Forbes list is an indication of the regions strength, resources, diversity and the opportunities it offers, said Christopher Bruhl, president and chief executive officer of the Business Council of Fairfield County.

The county has challenges, Bruhl said, but its strengths create the resources to meet them.

"Our wealthiest residents, who are our highest taxpayers and tend to be among our most generous philanthropists," he said, "are a great example of this fact of Fairfield County life."
