Credit card delinquency at the end of second quarter of 2014 had dropped nearly 9% to 1.16%, according to the national credit data firm TransUnion.

This was a sharp decrease from the 1.27% delinquency in credit cards in the second quarter of 2013 and the lowest rate of credit card delinquency since 2007, the data showed.

“Consumers continue to have a good handle on their credit cards, with delinquencies at all-time lows across the spectrum,” said Ezra Becker, vice president of research and consulting in TransUnion's financial services business unit. “We observed that delinquency rates are dropping for all age groups, and at relatively similar rates.”

The firm reported credit borrowers between the ages of 30 and 39 lowered their rate of delinquency by 10.31%, from 1.74% as of Q2 2013 to 1.56% in Q2 2014. Other age brackets also showed delinquency declines.

Transunion's data revealed consumers, on average, added very little to their credit card debt. Average credit card debt moved from $5,226 per account in 2013 to $5,234 per account in 2014. However, consumers in the 50 to 59 age bracket increased their credit card balances by 0.60% and cardholders over the age of 60 increased their balances by 1.86%.

Part of the reason for the increases was the 40 to 60-year old age range remains the peak years for both earning and purchasing with cards and other means as well, according to TransUnion.

“Traditionally, consumers carry heavier debt loads between the ages of 40 and 60 as they are in their peak purchasing years,” Becker said. “They also tend to spend more on items such as new cars, home furnishings (and) college tuition for their children.”

He added, “As we've noted in recent quarters, younger consumers continue to have lower debt levels, which can be attributed in part to limited access to card credit and a greater reliance on debit cards, among other factors.”
