Idaho might be number 16 on this list, but we would like to point out that its murder rate is very low. At 1.9 per 100,000 people per year, it's the seventh lowest in the entire country. So, well done to Idaho! And unlike some other states, it also has an extremely low rate of other violent crimes such as robbery, rape and sexual assault, and grievous bodily harm - at 215.6 per 100,000 people, it's the fifth lowest in the country.
