For a decade now, all the major auto insurers have used a customer’s credit rating to some degree in determining premiums. They claim that it results in lower rates for “most” customers, and that the data prove that people with lower credit scores make more claims and for higher amounts. The FTC released a report this summer that validated the practice—but also confirmed an unpleasant truth critics have been saying for years: because a higher percentage of Hispanics and African-Americans have low credit scores, there’s a good chance they’re disproportionately affected.
