There are two national crime series which have data on crime rates and trends. The National Crime Victimization Survey (NCVS) is based upon a sample of households and includes both crimes that are reported to police and those that are not reported. The Uniform Crime Reports (UCR) is based upon local police reports which are compiled by the FBI. The two data series complement each other and both are “right” in terms of measuring what they are designed to measure. Please see the report, The Nation’s Two Crime Measures (NCJ 246832, BJS web), for more information.
The Bureau of Justice Statistics' (BJS) National Crime Victimization Survey (NCVS) is the nation's primary source of information on criminal victimization. Each year, data are obtained from a nationally representative sample of about 240,000 persons in about 150,000 households on the frequency, characteristics, and consequences of criminal victimization in the United States. The NCVS collects information on nonfatal personal crimes (rape or sexual assault, robbery, aggravated and simple assault, and personal larceny) and household property crimes (burglary, motor vehicle theft, and other theft) both reported and not reported to police. Survey respondents provide information about themselves (e.g., age, sex, race and Hispanic origin, marital status, education level, and income) and whether they experienced a victimization. For each victimization incident, the NCVS collects information about the offender (e.g., age, race and Hispanic origin, sex, and victim-offender relationship), characteristics of the crime (including time and place of occurrence, use of weapons, nature of injury, and economic consequences), whether the crime was reported to police, reasons the crime was or was not reported, and victim experiences with the criminal justice system.
Yes. The information is available in the Crime Against People with Disabilities series.
A victimization is a single victim or household that experiences a criminal incident. Criminal incidents or crimes are distinguished from victimizations in that one criminal incident may have multiple victims or victimizations. For violent crimes (rape/sexual assault, robbery, aggravated assault, and simple assault) and for personal theft/larceny, the count of victimizations is the number of individuals who experienced a violent crime. For crimes against households (burglary, trespassing, other theft, and motor-vehicle theft), each household affected by a crime is counted as a single victimization.
The most recent information we have available on identity theft can be found within the Victims of Identity Theft series.
Reports on violence in the workplace offer the latest information on nonfatal and fatal forms of violence against private-sector and government employees that occur where they are working or on duty.
NIBRS stands for National Incident-Based Reporting System. Unlike the FBI's Uniform Crime Reporting (UCR) Program, which only collects data on the most serious offense that occurs during a criminal incident, NIBRS collects data on each reported offense occurring during criminal incident. You can learn more about NIBRS in the NIBRS Edition of the FBI's CJIS newsletter.
Number of victimizations per 1,000 persons or households in a given population that occurred during the year.
Many surveys have a specific margin of error because all of the questions are asked of every person. For example if you ask an opinion question all of the respondents in the sample, everyone can give an opinion. The margin of error is different for different crimes and different findings in NCVS because questions are asked only of people who are victims of those crimes. There is a large margin of error around statistically rare crimes, such as rape/sexual assault. The margin of error is smaller around crimes which occur more frequently, such as property theft. Within a crime category such as violent crime, the margin of error around specific characteristics such as hospitalization may be larger than that for overall violent crime, since the estimates are based only on violent crime victims who experienced that characteristic.
Though the NCVS was originally designed to provide national level estimates of criminal victimization, BJS has recognized an increasing need for victimization data at the state and local level. BJS has developed multiple approaches for obtaining subnational NCVS estimates, see NCVS Redesign: Subnational for additional information about these approaches.
