Low-Income Students Succeed—When Given the Opportunity

Given the chance, students from low-income families do just fine in selective colleges. That’s one of the most critical conclusions of a groundbreaking new study from economists Raj Chetty, John Friedman, and their colleagues. The study involved looking at federal tax records to highlight schools that provide opportunities for socioeconomic mobility and shine a spotlight on those that don’t.

Among the paper’s many findings, the authors demonstrate that students from low- and high-income families had similar post-college earnings. In other words, when the authors ranked all students’ within a particular college based on post-college earnings, low-income students fell within a few thousand dollars of their high-income peers. They were just as likely to succeed after college as rich students who went to the same school.

Take Ivy League and other extremely selective institutions, for example. These schools typically enroll only very high-achieving students--and the data prove that those with low-income backgrounds fared just as well as the rich kids. When ranked by their post-college earnings, students with low-income parents fell barely below students with high-income parents. At Harvard, for instance, low-income students were in the 71st percentile for post-college earnings; meanwhile, high-income students were in the 78th--a difference of less than $4,000 a year in total wages, using the most recently available data. At MIT, the range was from the 76th percentile among low-income students to the 82nd; at Princeton, low-income students ranked in the 74th percentile, while high-income students ranked in the 80th. Duke holds the dubious distinction of the greatest difference in earnings within the Ivy-Plus category, with low-income students averaging in the 67th percentile and high-income students in the 80th, while Brown’s low-and high-income students were virtually indistinguishable in earnings.

This finding is particularly important for high-caliber institutions that generally have lower percentages of low-income students, like all of the institutions in the chart above. As the authors say, there’s no evidence institutions outcomes have been or will be negatively affected as a result of accepting more qualified low-income students. That lends credence to affirmative action policies designed to promote access for low-income students--particularly among those institutions with endowment to support significant need-based aid. For instance, as my colleague Steve Burd wrote in Undermining Pell: Volume II, Vassar College in Poughkeepsie, New York, has made great progress in increasing its enrollment of low-income students. After moving to need-blind admissions, the share of freshman students receiving Pell Grants doubled in just five years, from 12 percent to 24 percent. Yet the Chetty study shows that over a decade’s worth of students, Vassar’s low-income and high-income students’ earnings are comparable--within about $3,000 when looking at annual earnings measures.

And that’s true not just at Ivy League institutions; low- and high-income students within a college earned similar amounts after college across all types of schools. For instance, at highly selective public institutions like UT-Austin, SUNY-Stony Brook, and University of Florida, students from high-income backgrounds rank in about the 72nd percentile of post-college earnings; those from low-income backgrounds rank in the 67th. At selective private colleges like Brigham Young, Catholic University, and Xavier University, the typical earnings of high-income students are in the 64th percentile, compared with earnings of low-income students in the 57th percentile. And at open access schools like community colleges, high-income students earned in the 54th percentile, compared with the 46th for low-income students. Across the board, the difference within colleges between the percentile earnings ranks of high- and low-income students was in the single digits.

Yet across all colleges, the average low-income student’s earnings were much lower--by a full 29 percentiles, on average. So how can it be true that low-income students do just as well as their peers in the same school, but fare so much worse on the national average?

For the most part, it’s a dilemma of access, not ability. Low-income students were much less likely to enroll at the most selective institutions, where earnings trend higher. At selective institutions, students fall well above the 50th percentile in earnings. But at non-selective, less-than-four-year, and for-profit institutions--where the bulk of low-income students enroll--earnings for all students who attend typically top out at a point much lower on the scale.

Selective colleges take the students with the strongest academic background, disadvantaging low-income students who attended underfunded high schools with fewer advanced course offerings and who didn’t have the benefit of SAT/ACT prep courses and college application coaches. And they provide opportunities for networking and name-brand schooling that nonselective institutions can’t afford their students.

And even among high-achieving low-income students, those selective colleges too often feel out of reach. Research from the Jack Kent Cooke Foundation found that among college applicants with high academic ability in high school, nearly half of high-income students applied to the most competitive schools, while fewer than a quarter of low-income students did. In many cases, that’s because they believe the school is financially out of reach, or lack the guidance many wealthy students have to submit top-notch applications.

This study proves that those with opportunity can succeed. The problem is, that opportunity can be too hard to come by. These data prove that top colleges can afford to admit many more low-income students--without risking their graduates’ odds of success.

In our next post, we’ll dive deeper into the issue of socioeconomic diversity at selective public and private nonprofit colleges, so check back soon.
