Investigator(s): United States Department of Justice. Federal Bureau of Investigation The National Incident-Based Reporting System (NIBRS) series is a component part of the Uniform Crime Reporting Program (UCR), a nationwide view of crime administered by the Federal Bureau of Investigation (FBI), based on the submission of crime information by participating law enforcement agencies. The NIBRS was implemented to meet the new guidelines formulated for the UCR to provide new ways of looking at crime for the 21st century. NIBRS is an expanded and enhanced UCR Program, designed to capture incident-level data and data focused on various aspects of a crime incident. The NIBRS was aimed at offering law enforcement and the academic community more comprehensive data than ever before available for management, training, planning, research, and other uses. NIBRS collects data on each single incident and arrest within 22 offense categories made up of 46 specific crimes called Group A offenses. In addition, there are 11 Group B offense categories for which only arrest data are reported. NIBRS data on different aspects of crime incidents such as offenses, victims, offenders, arrestees, etc., can be examined as different units of analysis. The data are archived at ICPSR as 13 separate data files, which may be merged by using linkage variables. NACJD has prepared a resource guide on NIBRS.

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). NIBRS is an annual data collection that compiles information on criminal incidents and arrests reported by participating law enforcement agencies. NIBRS data as formatted by the FBI are stored as a series of single files 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. Significant computing resources are necessary to work with the data in its single-file format. In addition, the user must be knowledgeable about working with data in complex file types. The extract files version of the NIBRS files 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. For these reasons and the desire to facilitate the use of NIBRS data, ICPSR created the extract files. The data are not a nationally representative sample of crime in the United States.

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). In the late 1970s, the law enforcement community called for a thorough evaluative study of the UCR with the objective of recommending an expanded and enhanced UCR program to meet law enforcement needs into the 21st century. The FBI fully concurred with the need for an updated program to meet contemporary needs and provided its support, formulating a comprehensive redesign effort. 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, the FBI formulated new guidelines for the Uniform Crime Reports. The National Incident-Based Reporting System (NIBRS) was implemented to meet these guidelines. NIBRS data are archived at ICPSR as 13 separate data files per year, which may be merged by using linkage variables. The data focus on a variety of aspects of a crime incident. Part 4, Administrative Segment, offers data on the incident, itself (date and time). Each crime incident is delineated by one administrative segment record. Also provided are Part 5, Offense Segment (offense type, location, weapon use, and bias motivation), Part 6, Property Segment (type of property loss, property description, property value, drug type and quantity), Part 7, Victim Segment (age, sex, race, ethnicity, and injuries), Part 8, Offender Segment (age, sex, and race), and Part 9, Arrestee Segment (arrest date, age, sex, race, and weapon use). The Batch Header Segment (Parts 1-3) separates and identifies individual police agencies by Originating Agency Identifier (ORI). Batch Header information, which is contained on three records for each ORI, includes agency name, geographic location, and population of the area. Part 10, Group B Arrest Report Segment, includes arrestee data for Group B crimes. Window Segments files (Parts 11-13) pertain to incidents for which the complete Group A Incident Report was not submitted to the FBI. In general, a Window Segment record will be generated if the incident occurred prior to January 1 of the previous year or if the incident occurred prior to when the agency started NIBRS reporting. As with the UCR, participation in NIBRS is voluntary on the part of law enforcement agencies. The data are not a representative sample of crime in the United States.

The CT Department of Emergency Services and Public Protection makes data on crime in Connecticut available at https://ct.beyond2020.com/. Crime data is continuously collected from all law enforcement agencies in the state, validated and made available for reporting. Reports on this site are updated nightly.

The FBI NIBRS (National Incident-Based Reporting System) data is the way the FBI is currently asking police agencies across the US to report crime data in their jurisdictions. This is coming to replace the traditional Summary Reporting System (SRS) in which the data from crimes was aggregated and so many details of crimes were not recorded. NIBRS includes details on each single crime incident—as well as on separate offenses within the same incident—including information on victims, known offenders, relationships between victims and offenders, arrestees, and property involved in crimes. It is important to note that not all agencies in every state have contributed to the NIBRS, therefore as you can see in the image below, not all states have data covering all their population. https://www.googleapis.com/download/storage/v1/b/kaggle-user-content/o/inbox%2F6432833%2F589a07f0116dcb6fab8892d2fc74e966%2Fnibrs_pop_coverage_map_2021.png?generation=1672211210548630&alt=media" alt=""> All the data is available here

Effective March 7, 2024, the Los Angeles Police Department (LAPD) implemented a new Records Management System aligning with the FBI's National Incident-Based Reporting System (NIBRS) requirements. This switch, part of a nationwide mandate, enhances the granularity and specificity of crime data. You can learn more about NIBRS on the FBI's website here: https://www.fbi.gov/how-we-can-help-you/more-fbi-services-and-information/ucr/nibrs NIBRS is more comprehensive than the previous Summary Reporting System (SRS) used in the Uniform Crime Reporting (UCR) program. Unlike SRS, which grouped crimes into general categories, NIBRS collects detailed information for each incident, including multiple offenses, offenders, and victims when applicable. This detail-rich format may give the impression of increased crime levels due to its broader capture of criminal activity, but it actually provides a more accurate and nuanced view of crime in our community. This change sets a new baseline for crime reporting, reflecting incidents in the City of Los Angeles starting from March 7, 2024. With NIBRS, each criminal incident may reflect multiple offenses, resulting in more robust data than before. This may change the appearance of crime frequency, as multiple offenses per incident are reported individually.

An annual publication based on data submitted to the FBI’s Uniform Crime Reporting (UCR) Program via the National Incident-Based Reporting System (NIBRS) for one or more months of the calendar year. It presents an overview of the offense categories that show the diversity and complexity of the data collected via NIBRS. In addition, it includes detailed agency-level data by offense type.

These data are part of NACJD's Fast Track Release and are distributed as they were received from the data depositor. The files have been zipped by NACJD for release, but not checked or processed except for the removal of direct identifiers. Users should refer to the accompanying readme file for a brief description of the files available with this collection and consult the investigator(s) if further information is needed. This research examined the reliability of the Federal Bureau of Investigation's National Incident-Based Reporting System (NIBRS) arrests data. Data on crime incidents, including data on whether an arrest was made or a summons issued, are collected from hundreds of law enforcement agencies (LEAs) across the country and then combined by the FBI into a national data set that is frequently used by researchers. This study compared arrest data in a sample of cases from NIBRS data files with arrest and summons data collected on the same cases directly from LEAs. The dataset consists of information collected from the Massachusetts NIBRS database combined with data from LEAs through a survey and includes data on arrests, summons, exceptional clearances, applicable statutes and offense names, arrest dates, and arrestees' sex, race, ethnicity and age for a sample of assault incidents between 2011 and 2013 from the NIBRS. The collection contains one SPSS data file (n=480; 32 variables). Qualitative data are not available as part of this collection.

Estimated national, regional, and state figures using NIBRS data. Estimates are produced on the number and characteristics of incidents, offenses, victims, and persons arrested. For each indicator, as appropriate, three types of estimates are produced: • a total (i.e., the volume of crime) • a rate (i.e., the per capita amount of crime per the population served) • a percentage (i.e., the proportion of a crime attributable to a particular level of a characteristic). Estimates are produced in 109 estimate domains which, in addition to national estimates, include population groups, agency types, regions, and states.

This segment of NIBRS data provides information on property involved in crimes. The property is categorized items into 68 types—ranging from money and alcohol to explosives and pets—along with their estimated value. This data details the status of each item, indicating whether it was stolen, damaged, recovered, seized by police, or destroyed in an arson. For drug offenses, it records up to three seized substances, identifying specific drugs like marijuana or heroin as well as broader categories such as “other narcotics.” If more than three types are seized, the third category indicates additional substances beyond those listed. The dataset also quantifies drug seizures, specifying both the amount and the unit of measurement (e.g., grams, pills, plants).

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.

Summary Reporting System (SRS) and the National Incident-Based Reporting System (NIBRS) are part of the FBI's Uniform Crime Reporting system. SRS and NIBRS collect data on crime incidents that are reported by law enforcement agencies across the country. Because SRS and NIBRS data are collected differently, they cannot be compared.

NIBRS was created in the 1980s to collect more detailed information on crime. Washington NIBRS data begins in 2012.

NIBRS data are incident-level data that have highly detailed information for each crime that is reported to the police agency. This data has 10 segments. Each segment has different data about the crime. AdministrativeBasic information about the crime incident - this is basically metadata about the other segments for this crime. This includes the date of the crime, the number of offense segments, the number of victim segments, the number of offender segments, the number of arrestee segments, if the crime was cleared exceptionally and (if it was) what date it was cleared. ArresteeArrestee-level information for those who are arrested. This includes demographics (age, sex, race, ethnicity), the date of the arrest (can be different than the date of the crime), what weapon (if any) was used, and the outcome of the case if the arrestee was a juvenile. Group B Arrest ReportsArrestee-level information for those who are arrested for Group B crimes. This includes the same variables as the arrestee segment. OffenderOffender-level information for each offender. Includes offender demographics (age, sex, race, ethnicity).OffenseDetailed information about each crime. Includes the weapon used (if any), the location of the crime, if the offender was intoxicated (including drugs and alcohol), and what their bias motivation (if any) was (if there is one, this would be considered a hate crime). PropertyInformation about property involved in the crime (i.e. drugs or stolen property). This includes the value of the property, what type of the property it was, when it was recovered. For drugs, this includes the drug and its quantity. VictimVictim-level information for each victim of a crime. Includes victim demographics (age, sex, race, ethnicity), injury, and relationship to the offender(s).Window ArresteeWindows segments have the same columns as their non-window counterparts and are incidents that occurred prior to the year of data or prior to when the agency started reporting to NIBRS.Window Exceptional ClearanceWindows segments have the same columns as their non-window counterparts and are incidents that occurred prior to the year of data or prior to when the agency started reporting to NIBRS.Window PropertyWindows segments have the same columns as their non-window counterparts and are incidents that occurred prior to the year of data or prior to when the agency started reporting to NIBRS.Due to the large file size, each year is its own file. All segment headers are available except for the batch headers. What I did here was read the data into R and save it as R and Stata files. No other changes to the data were made. The data was downloaded as NIBRS Master Files for each year from the FBI's Crime Data Explorer website - https://crime-data-explorer.fr.cloud.gov/downloads-and-docs.

This segment of NIBRS data provides details on individuals arrested in connection with a crime incident, including age, sex, race, ethnicity, residency status, and the offense charged. This data also documents whether the arrestee carried a weapon at the time of arrest and, if applicable, whether a firearm was automatic. Unique variables in this segment include the arrest date, type, and juvenile processing status which indicates whether a juvenile arrestee was released without formal sanctions or referred to external authorities such as juvenile court, welfare agencies, or probation and parole departments.

This data represents incident reports written to capture incidents of crime that are reported to law enforcement, based on the FBI’s UCR Program Data Collections for the National Incident-Based Reporting System (NIBRS). Historical data is available back to 10/1/2018, before which the agency was using the Summary Reporting System (SRS). While the data collected is similar, it is not comparable across reporting systems. Available fields include:Case Number – Unique numerical identifier of the incident, which can be joined to the calls for service and arrests datasets.Report Date – The date when the crime occurred, or when it was reported to police, if the date of occurrence is not known.Report Time – The time when the crime occurred, or when it was reported to police, if the time of occurrence is not known.Status – The status of the case at the time the dataset was last updated.Sequence – All offenses per incident are reported in NIBRS. This is the sequence by order of severity.ATT/COM – Designation of whether the crime was attempted or committed.UCR Code – The FBI’s alphanumeric identifier for the type of crime being reported.Address – The block number and street or intersection of the incident.X – Mapping coordinate of the incident, projected as NC State Plane (feet).Y – Mapping coordinate of the incident, projected as NC State Plane (feet).District – The patrol district where the incident occurred.Beat – The patrol beat where the incident occurred, which is a sub-division of the district.Premise – The type of location where the incident took place.Weapon – The primary weapon used in violent crimes.Tract – The census tract where the incident occurred, based on 2010 census data.This dataset is updated annually. However, other resources for incident data are available and updated nightly, including the DPD Crime dataset on the City and County of Durham Open Data Portal and Community Crime Map web site by LexisNexis.
