The number of billionaires in the world has now reached an all-time high, according to a new report from Wealth-X, a research firm devoted to the ultrawealthy, and UBS. The billionaire tally grew by 7% from July 2013 to June 2014 to reach a total of 2,325.

The combined wealth of the world’s billionaires increased by 12% to $7.3 trillion over that period, which means that billionaires now control nearly 4% of the world’s wealth. “The members of this group of ultra wealthy individuals form one of the most exclusive clubs in the world: there is only one billionaire for every three million people on the planet,” the report says.

From where they live to where they go to college to the size of their bank accounts, these seven charts prove one thing: how different these uber-rich are from you and me.

Just how rich are billionaires?

There are billionaires and then there are uber-billionaires (ahem, Warren Buffett). The majority of the world’s billionaires fall into the first category — 56% of them have a net worth between $1 billion and $2 billion, and another third (31%) have wealth that ranges from $2 billion to $5 billion, the UBS report says. Meanwhile, fewer than 5% of the world’s billionaires are worth more than $10 billion.

Top 5 industries for billionaires

If you want to be a billionaire, you may want to rethink your career choice. Nearly one in five billionaires works in finance, banking and investment, and about one in 10 work in industrial conglomerates (this is particularly true of billionaires living in emerging markets). Furthermore, 63% of billionaires’ primary businesses are private companies, compared with just 31% that are public companies. The typical billionaire is actively engaged in two businesses (though they tend to be primarily engaged in just one) and sits on the boards of three clubs, organizations or institutions.

10 countries with the most billionaires per capita

The U.S. has the most billionaires in terms of sheer numbers, followed by China and the U.K. But the countries and territories with the most billionaires per capita might surprise you. Tiny Liechtenstein ranks number one, with 125 billionaires per million people (but only 5 billionaires total), followed by vacation hot spot Bermuda with 100 per million and Luxembourg with nearly 31 per million.

These “billionaire hot spots” exist for a variety of reasons, the report explains, including the fact that some billionaires relocate their businesses and residences to take advantage of these countries’ preferential tax regulations. Interestingly, while 100% of the billionaires in Bermuda and Luxembourg were foreign-born, none of the billionaires in Liechtenstein were.

10 most popular colleges for billionaires

Of the top 20 most popular schools for billionaires — in terms of the number of billionaires who have obtained their bachelor’s degree at these institutions — 16 were in the U.S. Not surprisingly, Ivy League schools top the list, with the University of Pennsylvania — home to the high-powered Wharton School of Business — nabbing the no. 1 spot, followed by Harvard and Yale. But several non-Ivy schools punctuate the top 10, including the University of Southern California, the University of California, Berkeley, the University of Mumbai, and the London School of Economics and Political Science.

How billionaires make their money

If you’re looking for a grain of hope that you may one day join the ranks of the billionaire club, this may be it: More than half (55%) of all billionaires were completely self-made, meaning they made their money on their own without the help of an inheritance. Fewer than 20% were billionaires solely because of an inheritance. “Entrepreneurship is still an essential precondition for most individuals to achieve billionaire status,” the report revealed. However, the total number of completely self-made billionaires has actually shrunk since 2013, while the number of people who inherited some or all of their billions grew sharply.

10 North American cities with the most billionaires

Last year, North America added more new billionaires (a net gain of 57) than any other region in the world. And most U.S. billionaires (64%) were fully self-made, with 29% of them having made their wealth in finance, banking and investment. Not surprisingly, more of these billionaires live in New York than any other city, followed by Los Angeles and San Francisco; the only non-U.S. city to make the North American top 10 was Toronto.

Billionaires’ favorite cities

Fully 34% of the world’s billionaires are based in just 20 cities; eight of these cities are in Asia while two (New York and Los Angeles) are in the U.S. New York, which has more billionaires than any city in the world, snags the top spot partially because of its role as the global financial capital of the world. Other fun facts: In no. 2 ranked Moscow, 100% of the billionaires are self-made. And in São Paulo, 25% of the billionaires are female — a higher rate than for any other top-20 city.
