Bill Gates took second place with a net worth of $67 billion and Spain’s Amancio Ortega is third with $57 billion.

While many people’s net worth grew in 2013, Mark Zuckerberg’s ranking dropped 31 spots.

According to The Associated Press, 1,426 people made Forbes magazine’s list of billionaires, a record-breaking number.

The United States has the most billionaires at 442.

The list included 138 women, with L’Oreal’s 90-year-old heiress Liliane Bettencort as the world’s richest woman.
