The Richest People in the World

Updated: Jul 27, 2017 10:54 AM ET | Originally published: May 25, 2017

The richest people in the world have a staggering amount of wealth — comparable to the GDP of small countries for some. Many of the world's richest, like Microsoft founder Bill Gates or Facebook co-founder Mark Zuckerberg are self-made and took an idea that they turned into a billion-dollar fortune. For others, like the Koch brothers of Koch Industries, their businesses were inherited, but their control of the company led to overwhelming amounts of wealth.

Many billionaires donate a large percentage of their money to charity. In fact, several of the world's richest have made "The Giving Pledge," which means they have vowed to give away at least half of their wealth to charity.

There are more than 2,000 billionaires in the world, Forbes reported, and that number is only expected to grow. Based on recent estimates from Forbes, the world's richest people range from tech CEOs to heiresses to expert investors. Read on to find out how and why these people got so rich.

Who is the richest man in 2017?

Amazon founder Jeff Bezos surpassed Bill Gates in July to become not only the world's richest man, but the richest person in the world with an estimated net worth of $90.6 billion.

This has been a big year for Amazon, and in turn Bezos, which bought Whole Foods on June 16 and also had a record-breaking Amazon Prime Day.

Bezos, who bought The Washington Post in 2013 for $250 million, owns about 17% of Amazon.com, which is part of what buoyed him to the world's richest man. Amazon's stocks surged ahead of the online retail giant's quarterly earnings report, adding at least $1 billion to Bezo's overall net worth.

Who is the richest woman in 2017?

French heiress Liliane Bettencourt is the richest woman in the world and ranks among the world's top 20 richest overall, with a $39.5 billion net worth, Forbes reported. Her father, Eugene Schueller, founded the iconic cosmetics company L’Oréal in 1907, and Bettencourt owns a third of the makeup brand with her children. The 94-year-old is her father’s only child and inherited his fortune when he died in 1957. She also is one of the principal shareholders at L’Oréal.

In 1987, Bettencourt, with her husband and daughter, founded the Bettencourt Schueller Foundation, which supports scientific research, the arts and social change in France. The foundation awards grants and prizes each year for projects addressing these categories.

Bettencourt’s children have managed her money since 2012 .

List of the 10 Richest People in the World
