In 2013, 46% of Harvard undergraduate students came from families in the top 3.8% of all American households (i.e., over $200,000 annual income). In 2012, the bottom 25% of the American income distribution accounted for only 3–4% of students at Brown, a figure that had remained unchanged since 1992. In 2014, 69% of incoming freshmen students at Yale College came from families with annual incomes of over $120,000, putting most Yale College students in the upper middle and/or upper class. (The median household income in the U.S. in 2013 was $52,700.)
