The FBI gathers data from approximately 17,000 law enforcement agencies, and the Uniform Crime Reports (UCR) is the annual publication of this data (FBI 2021). The UCR has comprehensive information from police reports but fails to account for the many crimes that go unreported, often due to victims’ fear, shame, or distrust of the police. The quality of this data is also inconsistent because of differences in approaches to gathering victim data; important details are not always asked for or reported (Cantor and Lynch 2000). As of 2021, states will be required to provide data for the National Incident-Based Reporting System (NIBRS), which captures more detailed information on each crime, including time of day, location, and other contexts. NIBRS is intended to provide more data-informed discussion to better improve crime prevention and policing (FBI 2021).
The U.S. Bureau of Justice Statistics publishes a separate self-report study known as the National Crime Victimization Survey (NCVS). A self-report study is a collection of data gathered using voluntary response methods, such as questionnaires or telephone interviews. Self-report data are gathered each year, asking approximately 160,000 people in the United States about the frequency and types of crime they’ve experienced in their daily lives (BJS 2019). The NCVS reports a higher rate of crime than the UCR, likely picking up information on crimes that were experienced but never reported to the police. Age, race, gender, location, and income-level demographics are also analyzed.
The NCVS survey format allows people to more openly discuss their experiences and also provides a more-detailed examination of crimes, which may include information about consequences, relationship between victim and criminal, and substance abuse involved. One disadvantage is that the NCVS misses some groups of people, such as those who don’t have telephones and those who move frequently. The quality of information may also be reduced by inaccurate victim recall of the crime (Cantor and Lynch 2000).
