Forbes 2017 Billionaires List: Meet The Richest People On The Planet
By Luisa Kroll and Kerry A. Dolan
It was a record year for the richest people on earth, as the number of billionaires jumped 13% to 2,043 from 1,810 last year, the first time ever that Forbes has pinned down more than 2,000 ten-figure-fortunes. Their total net worth rose by 18% to $7.67 trillion, also a record. The change in the number of billionaires -- up 233 since the 2016 list -- was the biggest in the 31 years that Forbes has been tracking billionaires globally. Gainers since last year’s list outnumbered losers by more than three to one.

Bill Gates is the number one richest for the fourth year in a row, and the richest person in the world for 18 out of the past 23 years. He has a fortune of $86 billion, up from $75 billion last year. Amazon’s Jeff Bezos had the best year of any person on the planet, adding $27.6 billion to his fortune; now worth $72.8 billion, he moved into the top three in the world for the first time, up from number five a year ago.
Warren Buffett had the second-best year, and the biggest gain since Donald Trump was elected president in November 2016. His $14.8 billion jump in 12 months was enough for him to grab back the number two spot from Amancio Ortega, founder of Spanish clothing chain Zara. Ortega’s fortune was up $4.3 billion since last year, but he still fell to fourth in the world, unable to keep up with the outsize gains of others.
