National Incident-Based Reporting System, 1996: Extract Files (ICPSR 22881)
Alternate Title: NIBRS, 1996
Principal Investigator(s): National Archive of Criminal Justice Data
The National Incident-Based Reporting System (NIBRS) is a part of the Uniform Crime Reporting Program (UCR), administered by the Federal Bureau of Investigation (FBI). The extract files version of NIBRS was created to simplify working with NIBRS data. Data management issues with NIBRS are significant, especially when two or more segment levels are being merged. These issues require skills separate from data analysis. NIBRS data as formatted by the FBI are stored in a single file. These data are organized by various segment levels (record types). There are six main segment levels: administrative, offense, property, victim, offender, and arrestee. Each segment level has a different length and layout. There are other segment levels that occur with less frequency than the six main levels. Significant computing resources are necessary to work with the data in its single-file format. In addition, the user must be sophisticated in working with data in complex file types. For these reasons and the desire to facilitate the use of NIBRS data, ICPSR created the extract files. The data are not a representative sample of crime in the United States.
These data are freely available.

This study was funded by:
- United States Department of Justice. Federal Bureau of Investigation
- United States Department of Justice. Office of Justice Programs. Bureau of Justice Statistics
Scope of Study
Subject Terms: arrests, crime, crime rates, crime reporting, law enforcement agencies, national crime statistics (USA), offenders, offenses, property crime, Uniform Crime Reports, victims, violent crime
Geographic Coverage: United States
Date of Collection:
Universe: Law enforcement agencies in the United States participating in the National Incident-Based Reporting System.
Data Types: event/transaction data, survey data
Mode of Data Collection: self-enumerated questionnaire
Extent of Processing: ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:
- Checked for undocumented or out-of-range codes.
Original ICPSR Release: 2008-10-30
