National Crime StatisticS Exchange

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, is undertaking efforts to extend the ability to report more detailed information about crime in the United States. The goal of the NCS-X is to increase the number of agencies that report data to the FBI's National Incident Based Reporting System (NIBRS) so that nationally representative estimates of crime, based on detailed incident data, 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 from NIBRS—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, andSEARCH, 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 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.

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 and the National Incident-Based Reporting System (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 UCR 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, the 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.
