MIAMI (CBSMiami.com) One of the richest people in South Florida could be your neighbor. Well, maybe not YOUR neighbor, but the the richest man in Florida does live in Miami-Dade, according to the new Forbes 400 ranking of Americas billionaires released Wednesday.

That man is Mickey Arison, owner of the Miami Heat and boss of Carnival Cruise Line, the largest cruise company in the world. According to Forbes, Bal Harbour resident Arison is worth $4.2 billion, which makes him the richest person in South Florida and tied for the richest person in the state.

His financial equal is Dirk Ziff, also the youngest billionaire in the state at 47. Hes an investor who lives in Palm Beach.

The annual weath-o-rama compiled by Forbes Magazine is headed by Microsoft founder Bill Gates, at 55 worth $59 billion and considered the wealthiest man in America. Investment whiz Warren Buffett, who raised a furor when he said he and other rich people dont pay enough taxes, was a distant second at $39 billion. However, Buffett has given away a lot of his fortune to good causes, inviting other billionaires to join him.

Also in the top 10 are software guru Larry Ellison with $33 billion, hedge fund genius and Democrat money-machine George Soros with $22 billion, and (count them ) three heirs of Walmart founder Sam Walton, with a combined fortune of $67 billion.

Thats a lot of cheap t-shirts.

Is South Florida is filled with rich people?  Not according to Forbes ultra-rich list. Arison and Ziff, the richest people in the state, are barely in the top 100 at 75.

By Forbes reckoning, Florida has just 29 billionaires, and ten of them live in Dade, Broward or Monroe county.

Some are not exactly household names, like Bharat Desai of Fisher Island. He made his billion by outsourcing software jobs to foreign countries.

But some of the billionaires are very well known. How about H. Wayne Huizenga, the founder of Waste Management, AutoNation, Blockbuster Video, and onetime owner of the the Marlins, The Dolphins, and the Florida Panthers. Forbes said hes worth $2.3 billion.

Ed Anson, owner of Sunbeam Television and operator of TV stations in Miami and Boston, is worth $1.25 billion.

And the man who helped change the face of Miami-Dade government, auto dealer Norman Braman, is one of South Floridas billionaires, with a Forbes-estimated worth of $1.6 billion.

Only one billionaire is listed as living in The Keys, where you think anyone with a billion would want to live, but he should be easy to find. Just look for Rich; Robert Rich, who made his $2.1 billion fortune in frozen foods.

There are two final facts about Floridas 29 billionaires you can use to increase your wealth of knowledge. More than half of them are 70 or older, and they truly form an old boys club; there is only a single billionaire of the feminine gender in the Sunshine state. Ocalas Charlotte Colket Webers $1.2 billion fortune comes from Campbell Soup.

Thats truly mmm, mmm good!

Heres a list of the Florida billionaires, the wealthiest first:
