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.
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. See (link) for a more detailed explanation of each data set. 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.
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.
UCR stands for the Uniform Crime Reporting Program, a project of the FBI. You can learn more about the UCR program on the FBI website.
The NCVS and UCR both offer important information on criminal victimization; however, the two programs were created to serve different purposes. The primary objective of the UCR is to provide a reliable set of criminal justice statistics for law enforcement administration, operation, and management. The NCVS was established to provide previously unavailable information about crime (including crime not reported to police), victims, and offenders. More information on the similarities and differences between the NCVS and UCR can be found in Nation's Two Crime Measures
We develop national estimates from sample cases of interviews with victims. We take the data we get from these interviews and weight it to represent the nation as a whole. All of the published data from the survey represent weighted estimates. When the national estimate is based on 10 or fewer actual sample cases, we make note of this and encourage caution in interpreting results.
