The richest man in the world and two of the youngest billionaires are famous for not graduating from college—but, believe it or not, the overwhelming majority of the world's billionaires did indeed graduate.

Most of those listed in the Bloomberg’s Billionaire Index of the top 500 richest people in the world hold undergraduate degrees, and many have advanced degrees. Only 32 of the top 500 from the U.S. are college dropouts or did not attend college, plus there are numerous foreign billionaires who have no or limited college.

As one might guess, technology and real estate dominate the ways the uber-wealthy amassed their fortunes. Among the top 500 are 171 from the United States, while the rest live in other countries.

Which U.S. undergraduate programs can lay claim to educating the most billionaires? Ivy League schools are among the schools that rank high in producing billionaires, but the majority of billionaire are from non-Ivy League schools.

Following are the 15 U.S. undergraduate schools that have bestowed the most bachelor's degrees to billionaires from the U.S. and abroad, in ascending order. Along with the list of graduates are their ranks on the Bloomberg index, their wealth in billions, the country they are from, the industry associated with each, the year they graduated and the company they are most associated with. The list is based on the Bloomberg billionaire index as it stood on April 4.

By the way, the richest person in the world, Bill Gates, and two of the world's younger billionaires, Mark Zuckerberg and Dustin Muskovitz of Facebook fame, all dropped out of Harvard University.
