Advanced degree borrowers now account for roughly 40 percent of the nation's $1.6 trillion in total student loan debt, and a new study finds that some students are more likely to bear that burden than others.

The study, coauthored by Stanford University researcher Jaymes Pyne, examines the growth of graduate student debt in the U.S., and its disproportionate impacts on African Americans and economically disadvantaged students.

Pyne joins CPRE Knowledge Hub managing editor Keith Heumiller to discuss his findings, their implications, and some important takeaways for stakeholders across the country.
