Forbes has maintained a list of the worlds richest people for over 30 years. The richest comprise a little over 2 000 billionaires and in March this year, a then 21-year-old Kylie Jenner was added to the list becoming one of just eight that were under 30 and the youngest ever to amass a worth of over $1 billion.

The calculation is based on publically available data but is not always easy to determine. Billionaires typically have ways to limit who knows how much money they actually have.

The sale of 51% of Jenner’s cosmetics company to Cosmetic group Coty for $600 million is money in the bank and the sale price and revenue sales for 2018 value the company at $1,2 billion so her 49% ownership adds $588 million to her balance sheet making it official, she is the youngest billionaire ever to have created the fortune herself.
