More than half of all Americans are concerned about the level of personal debt they currently owe, with 27 percent saying they're very concerned, according to a survey by a national credit reporting company.

Dr. Alan F. Westin, a professor of public law and government at Columbia University, said an analysis of the recent Louis Harris-conducted survey reveals that Americans between the ages of 18-24, people with the least formal education, and blacks were most likely to express concern.Westin did the analysis for Equifax Inc., an Atlanta credit reporting company that requested the survey.

"Although 27 percent of the general public say they are very concerned, more than half of black Americans (56 percent) say they are very concerned about their current debts," Westin said. The survey shows 51 percent of the general public are generally concerned about their current debt.
