The most recent tally of the world’s wealthiest people by Forbes magazine put the Facebook founder’s net worth at $13.5 billion in 2011, ranking him 52nd in the world. But Zuckerberg’s 28.4% stake in Facebook could see his fortune rise to as much as $28.4 billion, assuming that Facebook’s valuation is $100 billion.

The telling chart below profiles the world’s richest people in age-adjusted terms (per age capita). At 27, Zuckerberg is number one on this list, with over $1B of wealth per each year of his life. In the top 100 richest people in the world, only the co-founders of Google, Larry Page and Sergey Brin, are also under 40.
