Stanford University has been ranked most entrepreneurial university in the US by Forbes. Half the universities in the top ten are located in Silicon Valley.

Forbes’s ranking compares the number of alumni who are listing themselves as founders and business owners on LinkedIn to the number of the university’s total student body. The magazine refers to this as the entrepreneurial ratio.

The list notes that some of Stanford’s most successful entrepreneurs to date did not actually earn a degree, including Google co-founders Larry Page and Sergey Brin, Snapchat developer Evan Spiegel and Jerry Yang and David Filo of Yahoo fame.

Massachusetts Institute of Technology takes second place, while University of California, Berkeley wins bronze. UCLA and Caltech take position five and six, respectively.

Cornell University is the top Ivy League member in fourth place, and indeed the east coast is trailing behind the west coast with Brown, Princeton and Dartmouth in seventh, eighth and tenth place, respectively. With Pepperdine University at number nine, the other two Ivy League schools can be found lower down the list: Yale University took 12th place while the University of Pennsylvania is in 42nd place. Columbia is not featured in the top 50 at all.
