MoneyGeek State Car Insurance Study: What’s In Our Data?

In this study, Quadrant Information Services provided data on annual car insurance premiums across 50 states and the District of Columbia, which the MoneyGeek team used to run a series of analyses across different driver profiles, vehicle types, coverage limits and other policy variations. Quadrant’s data covers the 4-6 largest providers in each state.

In the Teens section, we compared specific policies for a 50-year-old married couple against the same policy choices for a 50-year-old married couple with a 16-year-old driver on their policy. We also looked at specific policy choices that might increase or lower the annual premium for the couple with the 16 year old, such as speeding tickets, age and gender of the drivers, and driving discounts.

In the College Student section, we compared two different sets of policies – one for a 50-year-old married couple with a 16-year-old driver and another for a 50-year-old married couple with a 19-year-old driver. We also analyzed annual premium increases and decreases across policy variations for the 50-year-old married couple with a 19-year-old driver, such as distance from home, deductibles, and vehicle model year.

In the Military Drivers section, we compared policies for a single driver with standard civilian employment against policies for a single driver employed by the military. We also evaluated annual premium increases and decreases for both male and female military drivers across different age groups, and looked at how vehicle model and model year affected premiums as well.

We analyzed premium differences of these policy variations for the largest insurance providers (as measured by premiums written in each state) across the largest 25 cities and towns.
