Baton Rouge metro area residents cut the amount they owe on their credit cards by 14.7 percent in 2011, the 29th-largest reduction among the 100 metropolitan statistical areas hit hardest by credit-card debt, according to Equifax.

Shreveport-Bossier City residents cut their credit-card debt by 20.1 percent, the largest drop in the state and the fourth-largest among the metro areas on the Equifax list. The Lafayette area was 13th, with a reduction of 16.6 percent; and New Orleans was 52nd with a reduction of 11.2 percent.

Residents of Port St. Lucie, Fla., topped the list by cutting their credit-card debt by 23.6 percent.

The cities with the most sizable reductions are clustered in four states: Florida, Louisiana, Washington and California. Florida had five cities with the largest declines.

“It is interesting that MSAs from some of the states hardest hit by the recession showed some of the biggest reductions in credit card debt,” Trey Loughran, president of Equifax’s Personal Solutions business, said in a news release. “This suggests that consumers from these hardest hit areas have been especially cautious in their spending and diligent in paying down their credit card debt.
