> Also, many small towns have higher crime rates per capita than cities.
Per capita crime rates do not matter. What matters is the question "How likely am I to be the victim of a crime if I live in area X?".
Depending on the type of crime, you are around 4x as likely to be the victim of a violent crime if you live in a city[1].
Per capita rates is a statistical curiosity. Being 4x more likely to be shot is what people actually care about. When the population density is 10 - 100x different, a small difference in per capita rates is meaningless.
