For the first time in seven years, the number of billionaires in the world has dropped. In 2015, there were 1,826. In 2016, there are 1,810. The combined wealth of the world's billionaires dropped by $570 billion to $6.48 trillion. Individually, the net worth of billionaires decreased by $300 million to an average of $3.6 billion – the first time that has happened since 2010.
That said, 198 of the 1,810 billionaires in the world made the Billionaire's List for the first time in 2016. The class of 2016 is slightly smaller than 2015, which crowned 290 new billionaires. The newcomers to the Billionaire's List this year have a combined net worth of $344,100,000,000.
This year's new billionaires are a diverse bunch. They made their money in everything from drones to musical theatre, to French fries, to amusement parks, to after school tutoring, to, of course, tech startups.
Twenty-five members of the new billionaire's class of 2016 made their fortunes at startup companies valued at $1 billion or more. Of those 25, 18 of them are under age 40. The average age of these tech billionaires is 36 years old, which is half the average age of the whole list of 1,810 billionaires.
China had the most billionaire newcomers with 70. The U.S. came in second, with 33 and Germany in third with 28.
