Elon Musk tops Forbes' 2022 Ranking Of The World's Richest People for the first time with an estimated net worth of $219bn, in a year which marked the largest number of billionaire dropoff's since the 2009 financial crisis.

Regionally, Asia-Pacific boasts the most billionaires, with 1,088, followed by the United States, with 735, and Europe, with 592.

The list, revealed on 5 April, identified 2,668 billionaires in total, including 236 newcomers—far fewer than last year's 493. 

Altogether the total net worth of the world's billionaires is $12.7trn, down from last year's $13.1trn.

Following last year's record-breaking number of billionaires, the past 12 months have proven to be more volatile. The number of billionaires fell to 2,668, down from 2,755 last year.

A total of 329 people dropped off the list this year—the most in a single year since the 2009 financial crisis.

"The tumultuous stock market contributed to sharp declines in the fortunes of many of the world's richest," said Kerry A. Dolan, assistant managing editor of wealth, Forbes. "Still, more than 1,000 billionaires got wealthier over the past year. The top 20 richest alone are worth a combined $2 trillion, up from $1.8 trillion in 2021."
