Billionaires: 10 Intriguing New Facts About Who’s Getting Rich Now

A new Chinese billionaire was created almost every week in the first quarter of 2015, according to a just-released report by UBS and PwC.

"Asia's billionaires make up 36 percent of self-made billionaire wealth, overtaking Europe for the first time and second only to the U.S.," said Antoinette Hoon, private banking advisory services partner for PwC in Hong Kong. “Looking forward, we expect the region to be the center of new billionaire wealth creation.”

The report, which looked at data for 1,300 billionaires over 19 years, found – unsurprisingly -- that entrepreneurship is a powerful force for wealth creation. “Billionaires: Master architects of great wealth and lasting legacies" also noted that many billionaires are embracing philanthropy to build a legacy.

Here are 10 other findings of the report:

• 917 self-made billionaires generated more than $3.6 trillion of global wealth between 1995 and 2014.

• Of them, 23 percent launched their first business before age 30; 68 percent before turning 40.

• The second-highest number of self-made American billionaires (27.3 percent) in the last two decades came out of the tech sector.

• Finance produced 30 percent of U.S. billionaires, but they aren’t as rich as their counterparts in tech; their average net worth is $4.5 billion, compared with $7.8 billion for tech moneybags.

• In Europe and Asia, self-made billionaires mostly made their money in the consumer industry. Their wealth averages $5.7 billion. Tech entrepreneurs in Europe and Asia were the second-richest group with an average worth of $3.8 billion.

• More than two-thirds of global billionaires are over 60 years old and have more than one child.

• The average age of Asia billionaires is 57, 10 years younger than in the U.S. and Europe.

• About one fourth of Asian billionaires had impoverished childhoods, compared with 8 percent in the U.S. and 6 percent in Europe.

• 60 percent of self-made billionaires in the U.S. and Europe retain their businesses, 30 percent dispose of part of their business via an IPO or trade sale, with 10 percent selling outright.

• In Europe and Asia, billionaires are most likely to create a business dynasty, with 57 percent of European and 56 percent of Asian billionaire families, respectively, taking over the family business when the founder retires. In the U.S., just 36 percent of businesses remain family-run once the founder retires.
