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). 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) is being implemented to meet these guidelines. NIBRS data are archived at ICPSR as 13 separate data files, 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 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. For 2000, 18 states, fully or partially participating in NIBRS, were included in the dataset.

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 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. Additional data from DESPP is available here: https://portal.ct.gov/DESPP/Division-of-State-Police/Crimes-Analysis-Unit/Crimes-Analysis-Unit

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

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.

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.

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.

In 2021, the San Diego Police Department began reporting to the FBI’s National Incident-Based Reporting System (NIBRS) for statistics. NIBRS collects data on all crimes reported to law enforcement agencies, not just the highest charges within those crimes. Crime categories in NIBRS include crimes against Persons (i.e., assault, homicide, etc.), Property (i.e., burglary, theft, robbery, etc.), and Society (i.e., alcohol and drug offenses, weapon offenses, gambling, etc.). These new categories are a shift from the older FBI reporting style (UCR Summary) of simply reporting violent and property crime counts. For the most part, SDPD’s crime reporting will follow the NIBRS categories now. Historical data will still be posted to the Annual Crime Reports website. This dataset comprises of Crime Offense Data extracted from the San Diego Police Department’s Records Management System and includes information such as the date/time of the reported offense, offense category, underlying code sections, and the hundred block address where the incident occurred. This data is dynamic as records are updated daily and may change or be deleted as police investigations proceed. Records range from January 2020 – Present. The SDPD Neighborhood Crime Summary Dashboard visualizes this dataset. For more information on NIBRS reporting guidelines please refer to the FBI’s 2021.1 National Incident-Based Reporting System User Manual. For national NIBRS data, you can visit the FBI’s Crime Data Explorer.

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.

2025 NIBRS crime data for St. Louis County Police Department and additional St. Louis County Municipalities. Data is subject to change.

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.

Investigator(s): Federal Bureau of Investigation Since 1930, the Federal Bureau of Investigation (FBI) has compiled the Uniform Crime Reports (UCR) to serve as periodic nationwide assessments of reported crimes not available elsewhere in the criminal justice system. With the 1977 data, the title was expanded to Uniform Crime Reporting Program Data. Each year, participating law enforcement agencies contribute reports to the FBI either directly or through their state reporting programs. ICPSR archives the UCR data as five separate components: (1) summary data, (2) county-level data, (3) incident-level data (National Incident-Based Reporting System [NIBRS]), (4) hate crime data, and (5) various, mostly nonrecurring, data collections. Summary data are reported in four types of files: (a) Offenses Known and Clearances by Arrest, (b) Property Stolen and Recovered, (c) Supplementary Homicide Reports (SHR), and (d) Police Employee (LEOKA) Data (Law Enforcement Officers Killed or Assaulted). The county-level data provide counts of arrests and offenses aggregated to the county level. County populations are also reported. In the late 1970s, new ways to look at crime were studied. The UCR program was subsequently expanded to capture incident-level data with the implementation of the National Incident-Based Reporting System. The NIBRS data focus on various aspects of a crime incident. The gathering of hate crime data by the UCR program was begun in 1990. Hate crimes are defined as crimes that manifest evidence of prejudice based on race, religion, sexual orientation, or ethnicity. In September 1994, disabilities, both physical and mental, were added to the list. The fifth component of ICPSR's UCR holdings is comprised of various collections, many of which are nonrecurring and prepared by individual researchers. These collections go beyond the scope of the standard UCR collections provided by the FBI, either by including data for a range of years or by focusing on other aspects of analysis. NACJD has produced resource guides on UCR and on NIBRS data.

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.

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.

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.

In response to law enforcement’s need for more flexible, in-depth data, the Uniform Crime Reports (UCR) Program formulated the National Incident-Based Reporting System (NIBRS). NIBRS presents comprehensive, detailed information about crime incidents to law enforcement, researchers, governmental planners, students of crime, and the general public. A NIBRS fact sheet, written by the FBI can be found at http://www.fbi.gov/about-us/cjis/ucr/frequently-asked-questions/nibrs_faqs.

This data set contains Group A Offenses for the entire City. Please visit http://www.fbi.gov/about-us/cjis/ucr/nibrs to learn more about NIBRS. The "Data Collection Guidelines" outlines how this data is structured and provides the exact definitions and methodology behind this data set.

Reported crimes against persons and crimes against property based on National Incident Based Reporting System (NIBRS). Data reflects crime statistics reported to the Nevada Department of Public Safety on a monthly basis. Data is preliminary and subject to change without notice based on case updates.

The City of Henderson Police Department became NIBRS certified in 2020 before the January 1, 2021 deadline mandated by the FBI who compiles and publishes the Uniform Crime Report. The FBI requires all law enforcement agencies reporting crime statistics to utilize NIBRS standards and methodology instead of the previous Summary Reporting System (SRS) which was used by the City of Henderson from 1953 to 2020.

The Washington SAC provides access to crime statistics through several methods; CrimeStats Online, the Uniform Crime Report (UCR), and the National Incident Based Reporting System (NIBRS). Queries are web-based interfaces that allow users to query Washington crime data online. For more detailed analyses, the UCR and NIBRS data are available in Excel spreadsheets and SAS datasets. County-level summaries from the Criminal Justice Data Book are available in Excel as well.
