Self MadeCelebs

The study by PlayOJO looked at the backgrounds of the world’s highest-earning celebrities - all aged under 30 - to see how likely they were to make it big, based on their gender, age, ethnicity, nationality, place of birth and place of residence, education and birth month.

Each celebrity was assigned a percentage similarity score, which reveals how closely their backgrounds matched up to that of Forbes’ ideal entrepreneur. This ideal entrepreneur profile was based on demographic data pulled from the last five years' 30 Under 30 lists, looking specifically at those who work in entertainment, sports, music and social media.
