Communication of Innovation in Policing in the United States, 1996 (ICPSR 2480)
Released/updated on: 2005-11-04
Geographic coverage: United States
These data were collected to examine the patterns of communication among police planners in the United States. The focus was on information-sharing, in which police planners and others contact other law enforcement agencies directly to gather the information they need to manage their departments. This study examined this informal network and its role in the dissemination of police research. The Police Communication Network Survey was mailed to the chief executives of 517 local departments and all 49 state police and highway patrol organizations in March 1996. The chief was asked to forward the questionnaire to the commander of the department's planning and research unit. Questions covered the agency most frequently contacted, how frequently this agency was contacted, mode of communication used most often, why this agency was contacted, and the agency most likely contacted on topics such as domestic violence, deadly force, gangs, community policing, problem-oriented policing, drug enforcement strategies, civil liability, labor relations, personnel administration, accreditation, and police traffic services. Information was also elicited on the number of times different law enforcement agencies contacted the respondent's agency in the past year, the percentage of time devoted to responding to requests for information from other agencies, and the amount of training the respondent and the staff received on the logic of social research, research design, statistics, operations research, cost-benefit analysis, evaluation research, and computing. Demographic variables include respondent's agency name, position, rank, number of years of police experience, number of years in the planning and research unit, and highest degree attained.

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.

Law Enforcement Management and Administrative Statistics (LEMAS), 2013 (ICPSR 36164)
Released/updated on: 2015-09-22
Geographic coverage: United States
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.

Released/updated on: 2020-08-20
Geographic coverage: United States
The Law Enforcement Management and Administrative Statistics (LEMAS) survey collects data from a nationally representative sample of general-purpose agencies (i.e., local and county police departments, sheriffs' offices, and primary state police agencies). The 2016 LEMAS sample design called for the survey questionnaire to be sent to 3,499 general purpose law enforcement agencies, including 2,640 local and county police departments, 810 sheriffs' offices, and the 49 primary state police departments (Hawaii does not have a primary state police agency). The design called for all agencies employing 100 or more full-time equivalent sworn personnel to be included with certainty (self-representing), and for smaller agencies to be sampled from strata based on number of full-time equivalent sworn officers and type of agency. A total of 28 local police departments were determined to be out-of-scope for the survey because they had closed, had less than one full-time equivalent sworn officer, had contracted out their services with another law enforcement agency, or only had special enforcement responsibilities. The final mail out total of 3,471 agencies included 2,612 local police departments, 810 sheriffs' offices, and the 49 state agencies.

National Assessment of Criminal Justice Needs, 1983: [United States] (ICPSR 8362)
Released/updated on: 2006-01-18
In 1983, the National Institute of Justice sponsored a program evaluation survey by Abt Associates that was designed to identify the highest priority needs for management and operational improvements in the criminal justice system. Six groups were surveyed: judges and trial court administrators, corrections officials, public defenders, police, prosecutors, and probation/parole officials. Variables in this study include background information on the respondents' agencies, such as operating budget and number of employees, financial resources available to the agency, and technical assistance, research, and initiative programs used by the agency. The codebook includes the mailed questionnaire sent to each of the six groups in the study as well as a copy of the telephone interview guide.

National Manpower Survey, 1973-1976 (ICPSR 7675)
Released/updated on: 1992-02-16
Geographic coverage: United States
Time period: 1973-01-01--1976-01-01
This data collection contains information from a series of national surveys, conducted simultaneously across the criminal justice system, to ascertain national manpower strengths and goals, agency information and characteristics, and attitudes of the agency heads during the period 1973-1976. The National Manpower Survey was undertaken to assess the adequacy of existing federal, state, and local training and education programs meeting current personnel needs in various law enforcement and criminal justice functions and operations. The study intended to project future personnel and training needs, by occupation, in relation to anticipated availability of qualified personnel in order to assess the future adequacy of training and educational resources. It also sought to establish "needs priorities" as a basis for future training and academic assistance programs to be funded by the Bureau of Justice Statistics. The study design systematically covered the personnel needs in all state and local governmental agencies that were part of the law enforcement and criminal justice system. Sectors within the system included: (1) law enforcement, consisting of police departments and sheriff's agencies, ranging in size from one-person constabularies to large city departments employing 20,000 or more individuals, (2) corrections, including both adult and juvenile correctional institutions and agencies, and (3) the judicial process, including a wide range of courts with varying jurisdictions and scope, district attorneys or prosecutors' offices, and public defenders' offices. For this study, the Bureau of Social Science Research was responsible for the acquisition and assessment of existing statistical data as well as the design and execution of systematic mail surveys of agencies, officials, and employees within the law enforcement/criminal justice system. Nine nationwide surveys were directed to executives in criminal justice agencies, including chiefs of police (in both large and small departments), sheriffs (in both large and small departments), chief prosecutors, chief defenders, court administrators, wardens of adult correctional facilities, directors of juvenile correctional facilities, and chief probation and parole officers. Two additional surveys were sent to general and appellate jurisdiction courts. In the nine surveys directed to criminal justice executives, the instruments asked respondents for (1) an overall assessment of manpower problems, including personnel categories in which critical shortages might exist, and total personnel required to fulfill all agency duties and responsibilities, (2) desired and actual entry level standards, as well as entry level and in-service training content and requirements, (3) demographic, educational, training, and occupational background information about the executive respondent, (4) opinions about major obstacles to effectiveness and attitudes toward various issues such as team policing, plea bargaining, and computer-assisted case management, and (5) a fact sheet section dealing with agency employment by occupational category, salaries, and workloads. Each of the remaining two surveys was a census of general and appellate jurisdiction courts designed to yield basic statistical information regarding the courts and court systems' current staffing, training activities, and caseloads, and did not seek any attitudinal or subjective responses. Thus the agency itself was the reporting unit, with the respondent required only to be in a position to provide accurate, reliable information.

Survey of Campus Law Enforcement Agencies, 2011-2012 (ICPSR 36217)
Released/updated on: 2015-08-13
Geographic coverage: United States
Time period: 2011-01-01--2012-01-01
These data are from the Bureau of Justice Statistics' (BJS) 2011- 12 Survey of Campus Law Enforcement Agencies. In preparation for the survey, a universe list of 4-year and 2-year campuses was compiled using the United States Department of Education's Integrated Postsecondary Education Data System (IPEDS).
The survey focused primarily on agencies serving 4-year universities and colleges with a fall headcount enrollment of 2,500 or more. In addition, 2-year institutions with 2,500 or more students and a sample of 4-year institutions with 1,000 to 2,499 students were surveyed. These campuses are covered in a separate report. Schools were classified according to the level of the highest proportion of degrees awarded. The survey excluded:
- United States military academies and schools,
- for-profit institutions,
- schools operating primarily online.
Of the 905 4-year campuses with 2,500 or more students identified as being potentially eligible for the 2011-12 survey, 861 reported that they were operating their own campus law enforcement agency. These 861 agencies were asked to provide data describing their personnel, functions, expenditures and pay, operations, equipment, computers and information systems, community policing activities, specialized units, and emergency preparedness activities. ICF International, with the assistance of BJS, served as the data collection agent. BJS also conducted surveys of campus law enforcement agencies covering the 1994-95 and 2004-05 school years. The reports produced from these surveys are available on the BJS Web site and data are available on the ICPSR Web site.
