Data Collected by FBI

  • Voluntary
  • Collected from Police Departments
  • SRS – “The FBI’s reporting system for summarizing crime trends and arrests known to law enforcement. Data is collected at the aggregate level and lacks incident-based details for crimes other than homicide. Local, state, and federal law enforcement agencies tally the number of Part I offenses along with arrest data for Part I and Part II offenses, and submit the totals in a monthly summary report to the FBI or state Uniform Crime Reporting Program. The Hierarchy Rule governs multiple offenses within this system.” In Glossary - https://crime-data-explorer.app.cloud.gov/#

Data Collected by FBI

  • NIBRS – “The National Incident-Based Reporting System, or NIBRS, was implemented to improve the overall quantity and quality of crime data collected by law enforcement by capturing more detailed information on each single crime occurrence. It is the FBI’s incident-based reporting system for crimes known to law enforcement. Local, state, and federal law enforcement agencies collect a variety of details about each incident, including the time and location of the crime; the circumstance of the incident; the characteristics of the victim and offender (age, sex, race, and ethnicity); the victim’s relationship to the offender; the involvement of weapons or drugs; property loss; and whether the crime was motivated by bias. Law enforcement agencies are still in the process of adopting NIBRS. During this period of transition, the FBI converts incident-based data to the traditional Summary Reporting System (SRS) format for the purpose of publishing national and state-level crime trends.” In Glossary - https://crime-data-explorer.app.cloud.gov/#
