Many consumers have been reluctant to build up credit card debt, which typically carries steeper interest rates than other loans.
Credit card usage has fallen sharply since the 2008 credit crisis. Four years ago, Americans had $1.03 trillion in credit card debt, an all-time high. In October, that figure was 17 percent lower.
During the same period, student loan debt has increased dramatically. The category that includes auto and student loans is 22 percent higher than in July 2008. That reflects in part the fact that many Americans who have lost jobs decided to go back to school to get training for new careers.
