National Crime StatisticS Exchange

“We need to improve the way we collect and analyze data so that we can see the full scope of what is happening in our communities. One way to do this is to increase participation in the National Incident-Based Reporting Systems (NIBRS). NIBRS includes more than mere summary statistics - the numbers of robberies or homicides across the country each year. It gives the context of each incident, giving us a more complete picture. We can use it to identify patterns and trends, and to prevent crime." FBI Director James B. Comey, December 9, 2015. Statement before the Senate Judiciary Committee, Washington, DC. Also see Director Comey's remarks on NIBRS at the 2015 IACP Annual Conference HERE.

The National Crime Statistics Exchange (NCS-X) initiative, which is being spearheaded by the Bureau of Justice Statistics (BJS), with the support of the Federal Bureau of Investigation (FBI) and other Department of Justice agencies, such as the Office for Victims of Crime (OVC), is undertaking efforts to expand the reporting of more detailed crime incident data among law enforcement agencies throughout the United States. BJS recently announced Phase II funding for state UCR/NIBRS programs, as well as Phase III funding for select large law enforcement agencies (i.e., those over 750 sworn officers). You can access both funding solicitations at the main BJS website. 

The goal of the NCS-X project is to increase the number of agencies that report data to the National Incident Based Reporting System (NIBRS) managed by the FBI so that nationally representative estimates of crime can be generated. Research indicates that if an additional 400 scientifically selected law enforcement agencies could begin reporting NIBRS data, then nationally representative estimates regarding the nature of crime, criminality, victimization, and law enforcement operations could be generated, helping policy makers evaluate the needs of their communities, assess the impact of programs and initiatives, and guide public policy development and government investments. 

A team of organizations, including IACPRTI International, the Police Executive Research Forum (PERF), the Integrated Justice Information Systems (IJIS) Institute, and SEARCH, the National Consortium for Justice Information and Statistics, is working with the BJS and the FBI to implement the NCS-X initiative. Activities include reaching out to all 50 states to learn more about their state Uniform Crime Reporting (UCR) and incident-based reporting programs, making initial contacts with the 400 sampled law enforcement agencies, and introducing the NCS-X project to stakeholders in the law enforcement community. The benefit of the approach contemplated by the NCS-X program is that it leverages existing incident reporting programs and data standards to efficiently harvest automated, incident-based data to augment the NIBRS program for nationally representative estimates of crime.

IACP/MCCA/NSA/MCSA Joint support for nibrs

The International Association of Chiefs of Police (IACP), Major Cities Chiefs Association (MCCA), National Sheriffs' Association (NSA), and the Major County Sheriffs' Association (MCSA) released a joint statement supporting modernizing crime reporting, updating data to be collected to more accurately reflect current crime and related activities, the transition of the FBI Uniform Crime Reporting (UCR) program for all law enforcement agencies to the National Incident-Based Reporting System (NIBRS), and retirement of the Summary Reporting System (SRS). This joint statement of support, issued on August 26, 2015, can be found HERE.  In addition to this joint statement of support, the IACP approved a resolution Modernizing Nationwide Crime Reporting and Updating Data to be Collected to More Accurately Reflect Current Crime and Other Data, Such as Use of Force By and Against Police. This resolution, which was sponsored by the Research Advisory Committee, Victim Services Committee, CJIS Committee, and Communications & Technology Committee, can be found HERE


Crime incident reporting plays a vital role in supporting crime analysis and local law enforcement operations and deployment. In addition, incident reporting supports the collection and analysis of crime statistics for the United States at the national level. The Uniform Crime Reporting (UCR) program operated by the FBI includes both the Summary Reporting System (SRS) and the National Incident-Based Reporting System (NIBRS). SRS and NIBRS are cooperative statistical reporting initiatives operated by the FBI that gather crime and arrest data from law enforcement agencies throughout the United States. The SRS collects monthly submissions of aggregate crime and arrest reports from local, state, and tribal law enforcement agencies, while the NIBRS program collects detailed incident-based data on an expanded range of offenses. Each year the FBI publishes several reports assessing crime in the United States.

In addition to the annual reports produced by the FBI, BJS also compiles, analyzes, and publishes research on crime, criminal offenders, victims of crime, and the operation of justice systems at all levels of government.
