Society seems to be obsessed with rich people. We seek their advice, study theirhabits, and replicate their wealth-building strategies.

But the richest of the rich have more in common than a risk-taking attitude and an early morning routine.

Wealth-X, a firm that does research and valuations on ultra-high net worth (UHNW) individuals, recently revealed where the world’s wealthiest people — those with assets exceeding $30 million — went to college.

Counting alumni with both undergraduate and graduate degrees and leaving out those with diplomas, certificates, honorary degrees, and drop outs, Wealth-X determined which alma maters the world’s richest people share.

Harvard University is the former stomping ground to 1,906 millionaires and billionaires, which together command a net worth of $811 billion, more than twice that of the No. 2 school, University of Pennsylvania.

All together, five colleges with the richest alumni are public universities, six are Ivy League, and only one is located outside of the US. Though a degree from one of these schools won’t guarantee wealth, the odds may be in your favor if history is any indication.
