Where you keep your car directly affects your chances of having an accident or becoming a victim of theft or vandalism. The likelihood of encountering these problems increases in larger, more densely populated cities, while such incidents remain relatively low in rural areas.

Additionally, the time and efficiency of police response and law enforcement, local road and traffic conditions, and the quality of local medical services can affect regional insurance rates. Some insurers even factor in the litigation rates in a given area (how many lawsuits are filed, go to trial, out of court settlements, and their amounts).
