A new study on a metros’ propensity for credit card usage has found that some Southern cities have the highest level of impulse buyers. The research also found that two Northern cities had the highest average monthly expenditures using credit cards. According to survey, Stamford-Norwalk, CT, topped the list as the metro with the greatest likelihood of residents with a general-purpose credit card, and the area with the highest average monthly expenditures using credit cards in the entire country. Middlesex-Somerset-Hunterdon, NJ, ranked third with residents carrying any sort of credit card and sixth in overall credit card expenditures. Meanwhile, Jacksonville, NC, Punta Gorda, FL and Ocala, FL, were found to have the highest indexes of impulse buyers using payment cards. The research found that Honolulu tops the list with highest likelihood of its residents using gasoline credit cards. Anchorage ranks in the top five for metros with the highest likelihood of residents to have auto retail credit cards, and in the top ten for people with gas cards. NY-based MapInfo Corporation used its “PSYTE U.S. Advantage Neighborhood” cluster solution with data from Mediamark Research to conduct the study.
