Just over 21-hundred billionaires made this year's list, slightly lower than the year before.
Their total combined net worth is 8.7 trillion dollars, down from 9.1 trillion in 2018.
This year marks the first decrease in billionaires and their combined wealth since 2016.
One notable new addition is Kylie Jenner, who has become the world's youngest "self-made" billionaire, according to Forbes.
The magazine has received a heap of criticism for dubbing the youngest member of the wealthy Kardashian family a "self-made" billionaire.
Amazon CEO Jeff Bezos retains the top spot.
A total of 40 Koreans made the list, including Samsung Electronics Chairman Lee Kun-hee, who sits in 65th place, and Celltrion boss Seo Jeong-jin who stands 181st.
