An insurance score is a numerical ranking based on a person's credit history. Actuarial studies show that how a person manages his or her financial affairs, which is what an insurance score indicates, is a good predictor of insurance claims. Insurance scores are used to help insurers differentiate between lower and higher insurance risks and thus charge a premium equal to the risk they are assuming. Statistically, people who have a poor insurance score are more likely to file a claim. Insurance scores do not include data on race or income because insurers do not collect this information from applicants for insurance.
