Nearly 5 Million Americans in Default on Student Loans. Number surges in recent years despite strengthening economy .

The Wall Street Journal reports:

The number of Americans severely behind on payments on federal student loans reached roughly 4.6 million in the third quarter, a doubling from four years ago, despite a historically long stretch of U.S. job creation and steady economic growth.

In the third quarter alone, the count of such defaulted borrowers—defined by the government as those who haven’t made a payment in at least a year—grew by nearly 274,000, according to Education Department data released Tuesday.

The total number of defaulted borrowers represents about 22% of the Americans who were required to be paying down their federal student loans as of Sept. 30. That figure has increased from 17% four years earlier.

The money they owe is becoming a bigger share of total outstanding student debt in repayment. Defaulted student loans totaled $84 billion at the end of the quarter, or 13% of the roughly $631 billion that borrowers were required to be paying down.

A pretty amazing story.
