(AP) — It’s the latest snapshot of the growing burden of student debt and it’s another discouraging one: Two-thirds of the national college class of 2011 finished school with loan debt, and those who borrowed walked off the graduation stage owing on average $26,600 — up about 5 percent from the class before.

The latest figures are calculated in a report out Thursday by the California-based Institute for College Access and Success (TICAS) and likely underestimate the problem in some ways because they don’t include most graduates of for-profit colleges, who typically borrow more than their counterparts elsewhere.

Still, while 2011 college graduates faced an unemployment rate of 8.8 percent in 2011, even those with debt remained generally better off than those without a degree. The report emphasized research showing that the economic returns on college degrees remain, in general, strong. It noted the unemployment rate for those with only a high school credential last year was 19.1 percent.
