In 2013, the wealth of the world’s billionaires reached a record high — helped by 200 newcomers like Facebook founder Mark Zuckerberg. The 2013 Forbes Billionaires List names 1,426 billionaires with an aggregate net worth of $5.4 trillion, up a whopping 17% from $4.6 trillion last year. And that doesn’t include royalty or, um, dictators. Of those, some 442 make their home in the U.S. (there are 386 in the Asia-Pacific region, 366 in Europe, 129 in the rest of the Americas and 103 in the Middle East and Africa combined, according to Forbes). The average net worth of each U.S. billionaire: $10.8 billion, up from $9.1 billion last year, according to a separate survey released this month by private wealth consultancy Wealth-X and UBS.
