The big reason that D.C. makes the cut is population density. The entire district is basically an urban area, which leads to higher insurance rates. According to Census information, D.C has a population density of 11,020 people per square mile. While this number is certainly smaller than New York City, which clocks in at 28,256 people, it puts it well above other large cities, such as Houston and even Los Angeles.
