Editor’s Note: Today we are running the twelfth segment of the 15-part series on college-student-loan debt.  (Thank you to onlinecolleges.net for putting this together.)

The average defaulted loan is worth about $17,000.

That’s not a huge amount, but it can be hefty for those who don’t have jobs and nearly insurmountable for those with health problems or who have disabilities that keep them from working. Other factors besides health and income play into who will default as well, as students who attend for-profit colleges are twice as likely to default and those who drop out of school are four times as likely to default.
