Compstat and Organizational Change in the United States, 1999-2001 (ICPSR 25481)
Released/updated on: 2009-10-30
Geographic coverage: Minneapolis, United States, Lowell, Massachusetts, Minnesota, Newark, New Jersey
Time period: 1999-01-01--2001-01-01
The purpose of the study was to determine how Compstat programs were being implemented across the United States by examining the diffusion of Compstat and factors associated with its implementation. Another goal of the study was to assess the impact of Compstat on line or patrol officers at the bottom of the police organization. The researchers administered a national survey on Compstat and problem solving in police agencies (Part 1) by mail to all 515 American police agencies with over 100 sworn police officers, and to a random sample of 100 agencies with between 50 and 100 sworn officers. The researchers received a total of 530 completed surveys (Part 1) between June 1999 and April 2000. The researchers distributed an anonymous, voluntary, and self-administered survey (Part 2) between December 2000 and May 2001 to a total of 450 patrol officers at three police departments -- Lowell, Massachusetts (LPD), Minneapolis, Minnesota (MPD), and Newark, New Jersey (NPD). The Compstat Survey (Part 1) contains a total of 321 variables pertaining to executive views and departmental policy, organizational features and technology, and comments about problem solving in police agencies. The Line Officer Survey (Part 2) contains a total of 85 variables pertaining to the patrol officers' involvement in Compstat-generated activities, their motivation to participate in them, and their views on these activities.

Data in this collection examine the processing of federal offenders. The Cases Terminated files (Parts 1-3 and 25-28) contain information about defendants in criminal cases filed in the United States Federal District Court and terminated in the calendar years indicated. Defendants in criminal cases may either be individuals or corporations, and there is one record for each defendant in each case terminated. Information on court proceedings, date the case was filed, date the case was terminated, most serious charge, and reason for termination is included. The Docket and Reporting System files (Parts 4-7, 31-34, and 42) include information on suspects in investigative matters that took an hour or more of a United States Attorney's time with one of the following outcomes: (1) the United States Attorney declined to prosecute, (2) the case was filed in Federal District Court, or (3) the matter was disposed by a United States magistrate. Codes for each disposition and change of status are also provided. The Pretrial Services data (Parts 8, 22, 43, and 47) present variables on the circuit, district, and office where the defendant was charged, type of action, year of birth and sex of the defendant, major offense charge, and results of initial and detention hearings. The Parole Decisions data (Part 9) contain information from various parole hearings such as court date, appeal action, reopening decision, sentence, severity of sentence, offense, and race and ethnicity of the defendant. The Offenders Under Supervision files (Parts 15-16 and 37-40) focus on convicted offenders sentenced to probation supervision and federal prisoners released to parole supervision. The Federal Prisoner files (Parts 18 and 20) supply data on when an offender entered and was released from confinement, as well as the amount of time served for any given offense. The Administrative Office of the United States Courts data files (Parts 44, 52, and 53) contain records of defendants in criminal cases filed in Federal District Court and terminated in the calendar years indicated. There is one record for each defendant in each case. Variables include the date the case was filed, offense level, AO (Administrative Office) codes, and disposition date. The Bureau of Prisons data (both the Master and Detail files, Parts 45, 46, and 54-57 -- formerly known as the Federal Prisoner files) contain records of sentenced prisoners admitted to or released from federal prison during 1992-1994. These files consist of separate records for each prisoner's commitment to federal prison, and for each sentence imposed on a prisoner for a given commitment to federal prison. The Central System (CS) and Central Charge (CC) files of the Executive Office for United States Attorneys (EOUSA) include information about suspects in criminal matters and defendants in criminal cases in 1993-1994. Each defendant in a criminal matter has a master Central System record (Parts 50 and 51) and may have one or more Central Charge records (Parts 48 and 49). The Federal Probation/Supervision Data files (Parts 58 and 59) provide information on supervision procedures and the sequence of events and proceedings in 1992-1994 from the time a case was opened for supervision until the case was terminated. These include reports of parole violations, transfers of supervision to other districts, and case removals due to, for example, rearrest or hospitalization. The Sentencing Commission data (Parts 60 and 61) contain information on federal criminal cases sentenced in 1992-1994 under the Sentencing Guidelines and Policy Statements of the Sentencing Reform Act of 1984.

Juvenile Defendants in Criminal Courts (JDCC): Survey of 40 Counties in the United States, 1998 (ICPSR 3750)
Released/updated on: 2003-09-25
Geographic coverage: United States
This is an independent sample of juvenile defendants drawn from the State Court Processing Statistics (SCPS) for 1998 (see ICPSR 2038). SCPS 1998 tracked felony cases filed in May 1998 until final disposition or until one year had elapsed from the date of filing. SCPS 1998 presents data on felony cases filed in approximately 40 of the nation's 75 most populous counties in 1998. These 75 counties account for more than a third of the United States population and approximately half of all reported crimes. The cases from these 40 jurisdictions were weighted to represent all felony filings during the month of May in the 75 most populous counties. Data were collected on arrest charges, demographic characteristics, criminal history, pretrial release and detention, adjudication, and sentencing. Within each sampled site, data were gathered on each juvenile felony case. Cases were tracked through adjudication or for up to one year. The source used to identify the upper age for juveniles and the filing mechanism appropriate to each state was the OJJDP publication, Trying Juveniles as Adults in Criminal Court: An Analysis of State Transfer Provisions (December 1998).

Law Enforcement Agency Roster (LEAR), 2016 (ICPSR 36697)
Released/updated on: 2017-04-05
Geographic coverage: United States
Time period: 2015-01-01--2016-01-01
In the past several years, BJS has made efforts to develop a national roster of publicly funded law enforcement agencies. The Census of State and Local Law Enforcement Agencies (CSLLEA) represents the core of the BJS's law enforcement statistics program, and is currently used as the primary universe for all BJS law enforcement collections. The CSLLEA was last conducted in 2014 but encountered data collection issues. Since the last law enforcement universe list was the 2008 CSLLEA, BJS decided further work was needed to have a reliable and complete roster of law enforcement agencies. Using the 2008 and 2014 CSLLEA universe as the base, the LEAR integrated multiple datasets in an effort to compile a complete list of active general purpose law enforcement agencies. The goal of the LEAR was to serve as the universe list for which the Law Enforcement Management and Administrative Statistics (LEMAS) core and supplement samples could be pulled. The 2016 LEAR contains a census of 15,810 general purpose law enforcement agencies, including 12,695 local and county police departments, 3,066 sheriffs' offices and 49 primary state police departments. Staffing size from multiple datasets has also been merged into the LEAR file.

Law Enforcement Management and Administrative Statistics Body-Worn Camera Supplement (LEMAS-BWCS), 2016 (ICPSR 37302)
Released/updated on: 2019-06-20
Geographic coverage: United States
Time period: 2015-01-01--2016-01-01
Beginning in 2016, the Law Enforcement Management and Administrative Statistics (LEMAS) survey adopted a core and supplement structure. The LEMAS core has been conducted every 3 to 4 years since 1987 with approximately 3,200 local, county and state law enforcement agencies across the United States. Due to the breadth of the survey, detailed analysis of any specific law enforcement topic cannot be done with the LEMAS core. The LEMAS supplements are designed to fill this void by allowing for a more comprehensive examination on a key topic in law enforcement and are administered in between core years. The 2016 LEMAS Body-Worn Camera Supplement (LEMAS-BWCS) is the first supplement administered under the new structure.

The Law Enforcement Management and Administrative Statistics (LEMAS) survey collects data from a nationally representative sample of state and local law enforcement agencies in the United States. Although the data collection instrument (see page 150 of the codebook) uses the year 2012 for the title, most questions have a reference date of January 1, 2013. For this reason, the study title uses the year 2013. The 2013 LEMAS sample design called for the survey questionnaire to be sent to 3,336 general purpose state and local law enforcement agencies including 2,353 local police departments, 933 sheriffs' offices, and the 50 primary state law enforcement agencies. The design called for all agencies employing 100 or sworn personnel to be included with certainty (self-representing) and for smaller agencies to be sampled from strata base on number of officers employed. A total of 26 local police departments were determined to be out-of-scope for the survey because they were closed, outsourced, or operating on a part-time basis. A total of 38 sheriffs' offices were excluded from the survey because they had no primary law enforcement jurisdiction. The final mailout total of 3,272 agencies included 2,327 local police departments, 895 sheriffs' offices, and the 50 state agencies.

The collection itself dates back to the 1920s when it was under the Children's Bureau, however in 1974 the Office of Juvenile Justice and Delinquency Prevention (OJJDP), within the U.S. Department of Justice assumed responsibility for the work of promoting access to automated juvenile court data sets for juvenile justice research and policymaking efforts.
The Archive contains the most detailed information available on juveniles involved in the juvenile justice system and on the activities of U.S. juvenile courts. The Archive houses a sizable collection of automated juvenile court data files that not only support the national estimates but also support the study of a wide range of national and subnational juvenile justice issues. Designed to facilitate research on the juvenile justice system, the Archive's data files are available to policy-makers, researchers, students, and the public. The data have been used to explore a broad range of topics, from investigating the effectiveness of juvenile court programs and examining policy developments in individual jurisdictions, to monitoring the impact of legislative changes, and guiding juvenile justice system reform.

Originally known as the National Pretrial Reporting Program, the State Court Processing Statistics (SCPS) program tracks felony cases filed in May of a given year until final disposition or until one year has elapsed from the date of filing. This collection presents data on felony cases filed in approximately 40 of the nation's 75 most populous counties in even numbered years from 1990-2006 and 2009. These 75 counties account for more than a third of the United States population and approximately half of all reported crimes. The cases from these 40 jurisdictions are weighted to represent all felony filings during the month of May in the 75 most populous counties. Data were collected on arrest charges, demographic characteristics, criminal history, pretrial release and detention, adjudication, and sentencing.
