Violent crimes include murder, rape, robbery, and aggravated assault. Utah's violent crime rate in 2005 was 227, a 3.7% decrease compared with 2004. Since its peak in 1997, Utah's violent crime rate has generally continued to decrease. Utah's 2001 rate was the lowest the rate had been since 1987, and the 2005 rate was not much different than the 2001 rate. Although Utah's violent crime rate is about half the national rate, Utah's rate has been leveling while the national rate had been trending downward. The national rate increased in 2005.

Utah's adult arrest rate for violent crimes was 81 per 100,000 of those over 18 years of age.  This represents a 20.7% increase compared with 2004.

During 2005, there were 106 juvenile arrests for violent crimes per 100,000 of those aged 10 to 17.  This represents a 6.9% increase over 2004.

*Juvenile arrest rates should not be compared to adult arrest rates as they are based upon a much narrower population group.
