The Atlantic surveyed alumni from American Universities to find the ten that produced the wealthiest people.

There are various factors that affect these numbers. For example, a quarter of Brown and Cornell's ultra high net-worth alumni had their money only from inheritance.

Women who became the wealthiest came from Northwestern and Brown as these universities had the highest percent of the ultra high net-worth alumni being women. Fifteen percent were women compared to 2 to 4 percent of University of Chicago, MIT and Yale.
