About the National Incident-Based Reporting System (NIBRS)
The FBI UCR Program prepared this manual to assist LEAs in reporting crime statistics via the NIBRS. It addresses NIBRS policies, the types of offenses reported via the NIBRS, and guidelines for an agency to become certified to submit NIBRS data to the FBI. NIBRS Manuals Nebraska Incident-Based Reporting System (NIBRS) The Nebraska Incident-Based Reporting System (NIBRS) is used by law enforcement agencies for the purpose of collecting and reporting data on crime in their respective jurisdictions.
The National Incident Based Reporting System (NIBRS) is an incident-based reporting system for crimes known to the police. For each crime incident coming to the attention of law enforcement, a variety of data are collected about the incident. These data include the nature and types of specific offenses in the incident, characteristics of the victim(s) and offender(s), types and value of property stolen and recovered, and characteristics of persons arrested in connection with a crime incident.
Incident-based data provide an extremely large amount of information about crime. The information is also organized in complex ways, reflecting the many different aspects of a crime incident. Therefore this website provides a Resource Guide for learning about, accessing and using NIBRS data.

Using the Resource Guide
NACJD, a part of the Inter-University Consortium for Political and Social Research (ICPSR) at the University of Michigan,designed this Resource Guide for World Wide Web users to learn about the NIBRS dataset, to connect to other NIBRS information sources, and to easily create custom NIBRS datasets which include user specified variables and cases from multiple segment levels.
Much of the text in this Resource Guide comes from Federal Bureau of Investigation (FBI) publications. It has been edited to correspond to the topics of this website. The National Archive of Criminal Justice Data wishes to acknowledge and thank the FBI and the Bureau of Justice Statistics for their assistance and support in furthering the distribution and analysis of NIBRS data.

NIBRS and UCR
The Uniform Crime Reporting (UCR) Program, of which NIBRS is a part, is a city, county, state, and Federal law enforcement program. This program provides a nationwide view of crime based on the submission of crime information by law enforcement agencies throughout the country. The crime data are submitted either through a state UCR Program or directly to the national UCR Program, which is administered by the FBI. Since the 1930s, the data have been used in law enforcement administration, operation, and management, as well as to indicate the levels and nature of crime in the United States.
Throughout its first 60 years of operation, the UCR Program remained virtually unchanged in terms of the data collected and disseminated. As time progressed, a broad utility evolved for UCR data, and law enforcement expanded its capabilities to supply crime information. In the late 1970s, the law enforcement community called for a thorough evaluative study of UCR with the objective of recommending an expanded and enhanced UCR Program to meet law enforcement needs into the 21st century. Following a multiyear study, a 'Blueprint for the Future of the Uniform Crime Reporting Program' was developed. Using the 'Blueprint' and in consultation with local and state law enforcement executives, new guidelines for Uniform Crime Reports were formulated. The National Incident-Based Reporting System (NIBRS) is being implemented to meet these guidelines.
NIBRS offers law enforcement and the academic community more comprehensive data than ever before available for management, training, planning, and research. The implementation of NIBRS will be at a pace commensurate with the resources, abilities, and limitations of the contributing law enforcement agencies.
It is important to stress that while NIBRS is being implemented, the traditional UCR reporting format is still being used extensively.
Online Analysis of NIBRS Data
The Online Survey Documentation and Analysis is a set of programs for the documentation and web-based analysis of survey data and procedures for creating customized subsets of datasets. Online Data Analysis is available for NIBRS only for a selection of segments.
Online data analysis is recommended for users who would like to search for variables of interest in a dataset, review frequencies or summary statistics of key variables to determine what further analyses are appropriate, review frequencies or summary statistics for missing data, produce simple summary statistics for reports, create statistical tables from raw data, and those who would like to create custom subsets of cases or variables from a particularly large collection to save time in downloading and space on a personal computer.
