My recent article on student debt prompted many questions from readers who were hungry for more detail. I had provided statistics on all undergraduates, but many readers wanted to see debt for those who graduated with a bachelor’s degree.

When you break out the borrowing data by educational attainment, students who get bachelor’s degrees are more likely to borrow than the typical college student. This makes sense: When you stay in school longer, you have more years of tuition to pay and more opportunities to borrow. Fifteen percent of those with a B.A. borrowed more than $30,000, about double the rate of the typical college student. Five percent borrowed more than $50,000, compared with 2 percent of all college students.

These data are from the Beginning Postsecondary Students Longitudinal Study, the most comprehensive survey of student borrowing. It measured Class of 2003 students’ debt six years after entering college.

The longitudinal study is infrequent; we do not have comparable data for a more recent year. But for B.A. recipients there is more up-to-date information from the College Board comparing debt for the graduating classes of 2004, 2008 and 2012. The share of B.A. recipients who borrowed for college rose to 70 percent in 2012 from 65 percent in 2004. Further, the share borrowing relatively large amounts rose sharply. Just 2 percent of the class of 2004 borrowed more than $40,000, but that rose to 8 percent for the class of 2008 and 18 percent for the class of 2012.
