Recent Crime Statistics

About the Data Sources:
The Uniform Crime Report (UCR) is an annual compilation of complaints and arrests from over 18,000 law enforcement agencies across the country that voluntarily submit data to the FBI. It is used to compute crime rates, track and analyze trends in crime, and often mistakenly used as the measure of crime in the country, and in cities, counties, and states. The program has been used since 1930. UCR data tracks rates of eight key "index" crimes: 4 violent crime categories (murder and nonnegligent manslaughter, forcible rape, robbery, and aggravated assault), and 4 property crime categories (burglary, larceny-theft, motor vehicle theft, and arson). In computing an overall crime rate, all the index crimes have equal weight. Thus changes in the largest classes of offenses, such as aggravated assault or larceny-theft, have the greatest impact on the crime rate in a jurisdiction. If a person does not report a crime to the police for any reason, it does not get counted in the UCR. If the police do not record a complaint for some reason, it does not get counted.

The National Crime Victimization Survey (NCVS) is the largest survey of crime victims in America. Each year, a randomly selected nationally representative sample of over 135,300 participants are questioned about crimes committed against them over a year. The survey collects data on victimization by rape, sexual assault, robbery, assault, theft, household burglary, and motor vehicle theft. Because many crimes are not reported to the police, and some departments do not report to the UCR, the NCVS is considered by many to be a more accurate report on crime in the U.S.

Here are some differences between the UCR and NCVS:

 

UCR

NCVS

Geographic coverage

National, State, city, county and metropolitan area crime reports based on cumulating local agency reports

National estimates

Collection method

Reports by law enforcement to the FBI on a monthly basis

Annual survey of as many as 77,200 households and 134,000 individuals age 12 or older.

Measures

Index crimes and non-index crimes reported by law enforcement; additional detail on Index crimes such as murder weapons

Reported and unreported crime are not distinguished; additional details about the crimes, victims, and offenders

The UCR and NCVS are the primary sources of crime data in America. Below, we have compiled information about crime in America in 2010 using these sources. 

We've included from the UCR clearance rates for each crime type. Typically, a crime is "cleared" when a suspect is identified, even if no arrest is made. Clearance rates represent the percentage of reported crimes that have been cleared, typically due to the arrest of a person who is suspected of committing the crime or some exceptional circumstances. Clearance rates give us a sense of how many reported crimes remain unsolved. More information about clearance criteria according to the UCR can be found here


Murder in 2010
UCR (estimated number of offenses): 14,748
Cleared (murder & non-negligent manslaughter): 64.8% 

Forcible Rape in 2010
NCVS # of victimizations (rape/sexual assault): 188,380
UCR: 84,767 reported
Cleared: 40.3%
NCVS: Forced sexual intercourse including both psychological coercion as well as physical force. Forced sexual intercourse means vaginal, anal or oral penetration by the offender (s). This category also includes incidents where the penetration is from a foreign object such as a bottle. Includes attempted rapes, male as well as female victims, and both heterosexual and homosexual rape. Attempted rape includes verbal threats of rape.
UCR: Forcible rape, as defined in the FBI’s 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. In December 2011, this definition was revised to include rape of men and to eliminate the resistance requirement to better conform to modern state statutes. It will take effect in the Spring of 2012.

Robbery in 2010
NCVS # of victimizations: 480,750
UCR: 367,832
Cleared: 28.2% 

Aggravated Assault in 2010
NCVS # of victimizations: 725,180
UCR: 778,901
Cleared: 56.4% 

Burglary in 2010
NCVS # of victimizations: 2,923,430
UCR: 2,159,878
Cleared: 12.4%

Larceny & Theft in 2010
NCVS # of victimizations for personal theft: 138,340
NCVS # of victimizations for property theft:  14,769,990

UCR: Larceny-theft (except motor vehicle theft)- The unlawful taking, carrying, leading, or riding away of property from the possession or constructive possession of another. Examples are thefts of bicycles, motor vehicle parts and accessories, shoplifting, pocket-picking, or the stealing of any property or article that is not taken by force and violence or by fraud. Attempted larcenies are included. Embezzlement, confidence games, forgery, check fraud, etc., are excluded.
NCVS: Theft- Completed or attempted theft of property or cash without personal contact. Incidents involving theft of property from within the sample household would classify as theft if the offender has a legal right to be in the house (such as a maid, delivery person, or guest). If the offender has no legal right to be in the house, the incident would classify as a burglary.

Motor Vehicle Theft in 2010
NCVS # of victimizations: 606,990
