Corrections

Justice Expenditure and Employment Tool (JEET) 
The Bureau of Justice Statistics (BJS) has developed the Justice Expenditure and Employment Tool (JEET). The JEET is a new, modern interactive data visualization tool. Data for the JEET are extracted from two U.S. Census Bureau collections: the Annual Survey of State and Local Government Finances and the Annual Survey of Public Employment and Payroll. The JEET allows users to— 

•  explore expenditure, employment, and payroll statistics for three distinct categories—police protection, judicial and legal, and corrections—as well as for the total justice system 
• compare and rank states’ expenditures, employment, and payrolls across criminal justice functions 
• generate calculated metrics of expenditures per capita, number of employees per 10,000 residents, and average payrolls 
• view justice expenditure and employment statistics for the largest county and city governments in the U.S. 
• examine how state and local governments allocate resources for different criminal justice functions
• view changes in justice expenditures and employment over time. 

 The JEET currently includes data from 2016 to 2019. In the coming year, BJS plans to add historical data from 1982 onward. BJS will continue to enhance and expand the JEET based on the availability of resources.

Survey of Prison Inmates Data Analysis Tool (SPI DAT)

The Survey of Prison Inmates Data Analysis Tool (SPI DAT) is a new dynamic analysis tool that modernizes public access to the most recent SPI data (2016) with interactive visualizations. The SPI DAT allows users of all technical skill levels to readily analyze data, view selected charts, and create custom charts for a range of characteristics of the U.S. prison population. Filters can be selected to provide detailed results by specific characteristics. Users can choose to create data visualizations for persons in federal prisons, persons in state prisons, or all persons in U.S. prisons in 2016. Other modern features enable users to view additional statistics through the chart tooltip, display or hide chart footnotes, and download results.

Federal Justice System

Federal Criminal Case Processing Statistics (FCCPS) Tool

The Federal Criminal Case Processing Statistics (FCCPS) Tool is an interactive webtool that allows practitioners, policy makers, academics, and the general public to investigate and research various aspects about the federal criminal justice system. The FCCPS Tool enables the querying of data on the persons processed in the federal criminal justice system in nine cohorts across three case processing stages: (1) law enforcement, (2) prosecution/courts, and (3) incarceration. Additionally, see the Federal Criminal Case Processing Statistics (FCCPS) Tool Supplementary Information page for assistance with the tool.

Law Enforcement

Law Enforcement Agency Reported Crime Analysis Tool (LEARCAT)Update
The Bureau of Justice Statistics (BJS) established 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 the state, county, and agency levels
• produce custom views of the NIBRS data that provide information on various attributes of crime
• produce custom data sets for analysis
• generate univariate statistics and perform basic cross-tabulation analyses, among other functions.

LEARCAT contains NIBRS data from 2016 to 2023. BJS will enhance or expand data within the tool, based on the availability of data and resources.
