Forbes’ youngest billionaire of 2017 is just 21 years old.
A total of 2,208 billionaires make Forbes´ 32nd annual ranking of the world´s billionaires. Altogether they are worth $9.1 trillion, the highest total in the history of the ranking; up 18% from just one year ago.


As Jeff Bezos, Amazon CEO, is the richest person in the world, and Bill Gates and Warren Buffet follow, the Andresen sisters, Alexandra and Katharina, are the youngest billionaires of the annual list.
The daughters of Norwegian industrialist Johan H. Andresen, owner of Ferd AS, transferred ownership stakes of 42.2% to each Katharina and Alexandra, turning her net worth into an estimated $1.5 billion dollars.
Although Alexandra finds herself at ranking #1688, sharing position with her sister, she is barely 21 – turning 22 on July 23 –, one year younger than Katharina, which makes her the youngest World Billionaire of 2017 according to Forbes.
