We collected quotes from a variety of insurance companies across 2,700 towns and cities in the U.S. for 128 insurance companies. Our sample driver was a 30 year old male who drove a 2011 Toyota Camry. To obtain quotes, we kept parameters for getting coverage the same, such as that he was single, and had a clean driving record. The only parameter that changed was the zip code where he lived in the U.S. The amount of coverage we opted for gave our driver bit more than what is required of state minimums.
