NEW YORK — What could a Chinese dumpling maker and Mexican telecom mogul possibly have in common? They're among a record number of wealthy people who held the title of billionaire over the past year.

The tally of billionaires around the globe reached a high of 946, their combined wealth growing 35 percent to $3.5 trillion, according to Forbes magazine's 2007 ranking of the world's richest people.

The rich cashed in on strong equity markets, real estate and commodity prices worldwide, according to Forbes' billionaires co-editor Luisa Kroll.

"It's just been kind of an extraordinary year for markets worldwide," she said.

Leading the list are two men who manage to keep getting richer as they give more and more money away. Microsoft founder Bill Gates ranked No. 1 for the 13th straight year, beating out friend and fellow philanthropist Warren Buffett, chairman of Berkshire Hathaway Inc.

Gates' fortune rose $6 billion to $56 billion last year, while Buffett garnered an additional $10 billion to boost his net worth to $52 billion.

Only five Americans ranked in the top 20, though Americans account for 44 percent of the overall list.

Breathing down Buffett's neck was Mexican telecom giant Carlos Slim Helu, who added $19 billion to his existing fortune, the largest one-year gain over the past decade. With $49 billion to his name, Helu was just $3 billion shy of the No. 2 spot.

Starbucks Corp. chairman Howard Schultz and former Disney CEO Michael Eisner joined the ranks of the world's richest for the first time, behind new faces Mike Lazaridis and Jim Balsillie, Canadian co-chiefs of Blackberry maker Research In Motion Ltd.

The only Hawai'i resident on the list, Barbara Cox Anthony with a net worth of $12.6 billion, dropped to 47th place from 29th place last year.

Hawai'i-born Steve Case came in at No. 891 with a fortune of $1 billion — in a tie with part-time Big Island resident Marc Benioff, founder of San Francisco-based Salesforce.com.

Not making the ranking was Hawai'i real estate investor Gensiro Kawamoto, a Japanese citizen frequently referred to as being a billionaire.

Self-made mogul Li Wei, founder of Synear Food Holding, made the list for the first time along with a dozen other Chinese newcomers. Her company, one of the country's largest producers of frozen food, including sweet and meat dumplings, is an official supplier to the 2008 Beijing Summer Olympics.

All bets were off for online gambling moguls Ruth Parasol, Russell DeLeon and Calvin Ayre, who dropped from the list after recent crackdowns limiting offshore gambling Web sites.

Bumped from the top 20 were the Wal-Mart Stores Inc. heirs, who saw their company's stock languish, and Michael Dell, founder of computer maker Dell Inc. Losing billionaire status entirely was Yoshiaki Tsutsumi, the once-powerful Japanese industrialist who first topped the tally in 1987.

Japan surrendered its title as Asia's leading billionaire locale to India, which boasts 36 megarich on the list. Russia contributed 53 billionaires and now challenges Germany as home to the most billionaires outside the United States.

Among three Indians in the wealthiest top 20 are Mukesh and Anil Ambani, feuding brothers who got even richer after dividing their fortunes in 2005.
