The reason for the U.K.’s higher violent crime rate is their far broader definition of a “violent” crime....
According to the FBI, there are four crimes classified as “violent” in crime statistics: murder/non-negligent manslaughter, forcible rape, robbery and aggravated assault.
The list does not include burglaries, which is considered a property crime in the U.S. but a violent crime in the U.K.
The robbery rates were similar between the two countries:
U.S. 2009 robbery rate: 133 per 100,000.
U.K. 2009 robbery rate: 164 per 100,000.
The burglary rates were far higher in the U.S.:
U.S. 2009 burglary rate: 716.3 per 100,000
U.K. 2009 burglary rate: 523 per 100,000.
And in the U.S., you were nearly four times as likely to be murdered:
U.S. 2009 murder rate: 5 per 100,000.
U.K. 2009 murder rate: 1.49 per 100,000.
In addition to murder, forcible rape, robbery, aggravated assault and burglary, England and Wales classify domestic violence and all sexual offenses –- not just forcible rape –- as violent....
Sexual offenses include rape, sexual assault, sexual activity with children, soliciting prostitutes (but not prostitution itself), sexual threats, sexual touching and indecent exposure.
Domestic abuse, described as a form of “intimate personal violence,” includes the following: non-sexual emotional or financial abuse, threats, physical force, sexual assault and stalking carried out by a current or former partner or other family member.
Several other crimes that are classified as violent in the U.K. include vehicle theft, purse-snatching and bicycle theft.
In all, the definition of “violent crime” takes approximately six pages to thoroughly explain....
The U.S. also has a higher rate of murder, and most happen by way of gun: the FBI said 67.8 percent of murders in 2011 were by firearm.
