In the FBIs Uniform Crime Reporting (UCR) Program, violent crime is composed of four offenses: murder and nonnegligent manslaughter, forcible rape, robbery and aggravated assault. Violent crimes are defined in the UCR Program as those offenses which involve force or threat of force.
The data presented in Crime in the United States reflect the Hierarchy Rule, which requires that only the most serious offense in a multiple-offense criminal incident be counted. The descending order of UCR violent crimes are murder and nonnegligent manslaughter, forcible rape, robbery and aggravated assault, followed by the property crimes of burglary, larceny-theft and motor vehicle theft. Although arson is also a property crime, the Hierarchy Rule does not apply to the offense of arson. In cases in which an arson occurs in conjunction with another violent or property crime, both crimes are reported, the arson and the additional crime.
In 2011, an estimated 1,203,564 violent crimes occurred nationwide, a decrease of 3.8 percent from the 2010 estimate.
When considering 5- and 10-year trends, the 2011 estimated violent crime total was 15.4 percent below the 2007 level and 15.5 percent below the 2002 level.
There were an estimated 386.3 violent crimes per 100,000 inhabitants in 2011.
Aggravated assaults accounted for the highest number of violent crimes reported to law enforcement at 62.4 percent. Robbery comprised 29.4 percent of violent crimes, forcible rape accounted for 6.9 percent and murder accounted for 1.2 percent of estimated violent crimes in 2011.
Information collected regarding type of weapon showed that firearms were used in 67.7 percent of the nations murders, 41.3 percent of robberies and 21.2 percent of aggravated assaults. (Weapons data are not collected for forcible rape.) (See Expanded Homicide Data Table 7, Robbery Table 3 and the Aggravated Assault Table).

(Weapons data are not collected for forcible rape.) (See Expanded Homicide Data Table 7, Robbery Table 3 and the Aggravated Assault Table).
The FBIs Uniform Crime Reporting (UCR) Program defines murder and nonnegligent manslaughter as the willful (nonnegligent) killing of one human being by another.
The classification of this offense is based solely on police investigation as opposed to the determination of a court, medical examiner, coroner, jury, or other judicial body. The UCR Program does not include the following situations in this offense classification: deaths caused by negligence, suicide, or accident; justifiable homicides; and attempts to murder or assaults to murder, which are scored as aggravated assaults.
Supplementary Homicide Data-The UCR Programs supplementary homicide data provide information regarding the age, sex and race of the murder victim and the offender; the type of weapon used; the relationship of the victim to the offender; and the circumstance surrounding the incident. Law enforcement agencies are asked-but not required-to provide complete supplementary homicide data for each murder they report to the UCR Program. Information gleaned from these supplementary homicide data can be viewed in the Expanded Homicide Data section.
Justifiable homicide-Certain willful killings must be reported as justifiable or excusable. In the UCR Program, justifiable homicide is defined as and limited to:
The killing of a felon by a peace officer in the line of duty.
The killing of a felon, during the commission of a felony, by a private citizen.
Because these killings are determined through law enforcement investigation to be justifiable, they are tabulated separately from murder and nonnegligent manslaughter.
More information about justifiable homicide is furnished in the Expanded Homicide Data section and in Expanded Homicide Data (See , Justifiable Homicide by Weapon, Law Enforcement, 2007-2011 and Expanded Homicide Data Table 15, Justifiable Homicide by Weapon, Private Citizen, 2007-2011.
In 2011, an estimated 14,612 persons were murdered in the United States. This was a 0.7 percent decrease from the 2010 estimate, a 14.7 percent decline from the 2007 figure and a 10.0 percent decrease from the 2002 estimate.
There were 4.7 murders per 100,000 inhabitants, a 1.5 percent decrease from the 2010 rate. Compared with the 2007 rate, the murder rate declined 17.4 percent and compared with the 2002 rate, the murder rate decreased 16.8 percent. (See Tables 1 and 1A.)
Nearly 44 percent (43.6) of murders were reported in the South, the most populous region, 21.0 percent were reported in the West, 20.6 percent were reported in the Midwest and 14.8 percent were reported in the Northeast. (See Table 3.)
UCR expanded offs of the various offenses that the UCR Program collects beyond the count of how many crimes law enforcement agencies report. These details may include the type of weapon used in a crime, type or value of items stolen and so forth. In addition, expanded data include trends (for example, 2-year comparisons) and rates per 100,000 inhabitants.

Forcible rape, as defined in the FBIs Uniform Crime Reporting (UCR) Program, is the carnal knowledge of a female forcibly and against her will. Attempts or assaults to commit rape by force or threat of force are also included; however, statutory rape (without force) and other sex offenses are excluded.
The UCR Program counts one offense for each female victim of a forcible rape, attempted forcible rape, or assault with intent to rape, regardless of the victims age. A rape by force involving a female victim and a familial offender is counted as a forcible rape and not an act of incest. All other crimes of a sexual nature are considered to be Part II offenses; as such, the UCR Program collects only arrest data for those crimes. The offense of statutory rape, in which no force is used but the female victim is under the age of consent, is included in the arrest total for the sex offenses category. Sexual attacks on males are counted as aggravated assaults or sex offenses, depending on the circumstances and the extent of any injuries.
For this overview only, the FBI deviated from standard procedure and manually calculated the 2010 and 2011 rates of females raped based on the national female population provided by the U.S. Census Bureau.
There were an estimated 83,425 forcible rapes reported to law enforcement in 2011. This estimate was 2.5 percent lower than the 2010 estimate and 9.5 percent and 12.4 percent lower than the 2007 and 2002 estimates, respectively. (See Tables 1 and 1A.)
The rate of forcible rapes in 2011 was estimated at 52.7 per 100,000 female inhabitants.
Rapes by force comprised 93.0 percent of reported rape offenses in 2011 and attempts or assaults to commit rape accounted for 7.0 percent of reported rapes. (Based on Table 19)
The rate of forcible rapes in 2011 was estimated at 52.7 per 100,000 female inhabitants.

The FBIs Uniform Crime Reporting (UCR) Program defines robbery as the taking or attempting to take anything of value from the care, custody, or control of a person or persons by force or threat of force or violence and/or by putting the victim in fear.
In 2011, there were an estimated 354,396 robberies nationwide.
The 2011 estimated number of robberies decreased 4.0 percent from the 2010 estimate and 20.8 percent from the 2007 estimate.
When compared with the 2010 rate, the 2011 estimated robbery rate of 113.7 per 100,000 inhabitants showed a decrease of 4.7 percent. (See Tables 1 and 1A.)
Robberies accounted for an estimated $409 million in losses in 2011. (Based on Table 1 and Table 23.)
The average dollar value of property stolen per reported robbery was $1,153. (Based on Table 1 and Table 23.)Banks experienced the highest average dollar loss at $4,704 per offense. (See Table 23.)
Among the robberies for which the UCR Program received weapon information in 2011, strong-arm tactics were used in 42.3 percent, firearms were used in 41.3 percent and knives and cutting instruments were used in 7.8 percent of robberies. Other dangerous weapons were used in 8.7 percent of robberies in 2011. (Based on Table 19.)

The FBIs Uniform Crime Reporting (UCR) Program defines aggravated assault as an unlawful attack by one person upon another for the purpose of inflicting severe or aggravated bodily injury. The UCR Program further specifies that this type of assault is usually accompanied by the use of a weapon or by other means likely to produce death or great bodily harm. Attempted aggravated assault that involves the display of-or threat to use-a gun, knife, or other weapon is included in this crime category because serious personal injury would likely result if the assault were completed. When aggravated assault and larceny-theft occur together, the offense falls under the category of robbery.
In 2011, there were an estimated 751,131 aggravated assaults in the nation.
The estimated number of aggravated assaults in 2011 declined 3.9 percent when compared with data from 2010 and 15.7 percent when compared with the estimate for 2002.
In 2011, the estimated rate of aggravated assaults was 241.1 offenses per 100,000 inhabitants.
A 10-year comparison of data from 2002 and 2011 showed that the rate of aggravated assaults in 2011 dropped 22.1 percent. (See Tables 1 and 1A.)
Of the aggravated assault offenses in 2011 for which law enforcement agencies provided expanded data, 26.9 percent were committed with personal weapons such as hands, fists, or feet. Slightly more than 21 percent (21.2) of aggravated assaults were committed with firearms and 19.1 percent were committed with knives or cutting instruments. The remaining 32.8 percent of aggravated assaults were committed with other weapons. (Based on Table 19.)
