A study of Baltimore residents released by the Consumer Federation of America says that auto insurance companies often set rates based on an individual?s education and occupation. The study found that individual?s with just a high school diploma and blue-collar job repeatedly pay more for insurance than white-collar professionals. Based on quotes from several insurers? websites, the annual premium for a factory worker was usually higher than that of a plant-supervisor with a college degree. Authors of the study stressed the importance of comparison shopping for consumers.
