Empirical studies have shown that minorities pay more for goods and services, and that they pay more to finance their purchases of those goods and services -- for instance, through subprime home and auto loans. Machine Bias, a new study from ProPublica and Consumer Reports, adds car insurance premiums to the list of what minorities can expect to pay more for. The study uses zip codes to analyze auto insurance premiums and payouts in four states, California, Illinois, Texas, and Missouri. It finds that major insurers charge up to 30% more in minority neighborhoods as compared to white neighborhoods with the same risk profile. The results mean that where someone lives matters even more, and could have devastating consequences on upward mobility. When faced with budget-busting car insurance bills, do people give up the cars they need to get to work? Or do they go out without necessities, such as food and medicine, so they can pay their car insurance premiums?
