Hoxby says some college administers had confided to her that they had reluctantly come to the conclusion that the pool of low-income students with top academic credentials was just limited, and there wasn’t much they could do to change that.
But in an analysis published with Christopher Avery in December, Hoxby has shown that this conclusion isn’t true. There is in fact a vast pool of highly talented, low-income students; they just aren’t ending up in top schools.
"The students whom they see are the students who apply," she says, of admissions officers. "And if a student doesn’t apply to any selective college or university, it’s impossible for admissions staff to see that they are out there."
Hoxby found that the majority of academically gifted low-income students come from a handful of places in the country: About 70 percent of them come from 15 large metropolitan areas. These areas often have highly regarded public high schools, such as Stuyvesant in New York City or Thomas Jefferson in the Washington, D.C., area.
Low-income high-achieving students at these schools have close to 100 percent odds of attending an Ivy League school or other highly selective college, Hoxby says.
The reasons are straightforward: These schools boast top teachers and immense resources. They have terrific guidance counselors. Highly selective colleges send scouts to these schools to recruit top talent. And perhaps most important, students in these schools are part of a peer group where many others are also headed to highly selective colleges.
Hoxby and Avery found that top students who do not live in these major metropolitan areas were significantly less likely to end up at a highly selective school. These students were far less likely to find themselves in a pipeline that ended at an Ivy League school.
