This report describes BJS?s activities during 2021 and 2022 to collect data and report on human trafficking as required by the Combat Human Trafficking Act of 2015 (34 U.S.C. ? 20709(e)). It details ongoing and completed efforts to measure and analyze the nationwide incidence of human trafficking, to describe characteristics of human trafficking victims and offenders, and to describe criminal justice responses to human trafficking offenses. Additionally, it provides information on human trafficking suspects referred to and prosecuted by U.S. attorneys, human trafficking defendants convicted in U.S. district court, and admissions to state prison for human trafficking.
This report presents data on law enforcement agencies that employ at least one full-time equivalent sworn officer with general arrest powers and that are operated by state and local governments. The report provides the number of law enforcement officers and the size of the populations they serve. It also describes tribal police departments, sheriffs? offices, and law enforcement agencies with special jurisdictions.
The National Crime Victimization Survey and National Incident-Based Reporting System: A complementary picture of crime in 2021 describes the similarities and differences between crime estimates derived from the National Crime Victimization Survey (NCVS), sponsored by BJS, and the FBI?s National Incident-Based Reporting System (NIBRS). The NCVS and NIBRS measure a set of crime offenses that overlap but are not identical, which leads to differences in estimates between the two data sources. The NCVS interviews victims on crimes both reported and not reported to police, while NIBRS collects data on crimes recorded by law enforcement agencies. Taken together, these two measures of crime provide a more comprehensive picture of crime in the United States.
The publication includes statistical estimates from both data sources; both show that the rate of violent crime in 2021 was not statistically different from the rate in 2020.
This Just the Stats report presents findings on nonfatal carjacking victimization from 1995 to 2021, based on data from BJS?s National Crime Victimization Survey. It shows trend estimates of nonfatal carjacking victimizations and provides data on characteristics of carjackings and demographics of carjacking victims.
Carjacking Victimization, 1995?2021 is the first report in BJS?s new Just the Stats web-published series.
The Bureau of Justice Statistics has released the 2017?2020 National Incident-Based Reporting System (NIBRS) Extract Files through the National Archive of Criminal Justice Data. NIBRS is a part of the FBI?s Uniform Crime Reporting Program and is the nation's principal source of information on crimes and arrests recorded by participating law enforcement agencies. BJS developed the extract files to provide users access to NIBRS data that have been transformed into a format compatible for use with widely available analytic software. In these extract files, data elements from multiple NIBRS segment levels are?merged into a single concatenated file that can be analyzed at the level of the incident, the victim, or persons arrested.?
NIBRS collects annual data on 24 offense categories and includes information on?
- fatal and nonfatal violent crimes committed against victims of all ages
- property crimes committed against persons and businesses
- crimes against society, including animal cruelty, drug offenses, and weapon law violations
- demographic characteristics of victims, alleged offenders, and persons arrested
- whether offenders used a firearm or other weapon type
- hate crime incidents
- whether crimes resulted in arrest
- assaults and killings of law enforcement officers.
The Bureau of Justice Statistics has released three datasets for the 2018 National Survey of Youth in Custody dataset through the National Archive of Criminal Justice Data. This survey is part of the BJS National Prison Rape Statistics Program, which gathers mandated data on the incidence and prevalence of sexual assault in juvenile facilities under the Prison Rape Elimination Act of 2003 (PREA; P.L. 108-79). The two publicly available datasets include?
- youth characteristics
- youth opinions of the facility and staff
- interactions with staff members and the nature of those engagements.
The third dataset also includes information on sexual victimization and is available for approved research projects.
BJS developed the Law Enforcement Agency Reported Crime Analysis Tool (LEARCAT) to provide access to incident-based data on crimes recorded by law enforcement. LEARCAT uses data from the FBI?s National Incident-Based Reporting System (NIBRS), as well as contextual information from other federal data sources, such as the U.S. Census Bureau.
LEARCAT enables users to?
- examine NIBRS data at multiple levels of geography, including state, county, and agency levels
- produce custom views of the NIBRS data that provide information on various attributes of crime
- produce custom datasets for analysis
- generate univariate statistics and perform basic cross-tabulation analyses, among other functions.
LEARCAT includes NIBRS data from 2016 to 2021. BJS will enhance or expand data within the tool, based on the availability of data and resources.
