Inventory of Data Elements in State and Federal Corrections Information Systems, 1998 (ICPSR 2575)
Released/updated on: 2005-11-04
Geographic coverage: United States
This survey summarizes the data elements maintained by state and federal corrections information systems that track adult, sentenced offenders, and assesses the severity of obstacles in reporting statistical information. Two instruments, an Inventory Questionnaire and an Obstacles Survey, were mailed to Departments of Correction in all 50 states and the District of Columbia, and to the Federal Bureau of Prisons. The Inventory Questionnaire asked 207 questions about data elements describing offenders, 15 questions about elements describing facility management, and 20 questions about the capabilities of the information system to process data electronically. For some elements, questions were asked to determine if more detailed information (subvalues) about the element existed. The Obstacles Survey asked departments to rate the severity of problems they may encounter when processing requests for statistical information. The items were grouped into five categories: legislative and institutional factors, hardware factors, software factors, staffing factors, and data factors.

Use of Computerized Crime Mapping by Law Enforcement in the United States, 1997-1998 (ICPSR 2878)
Released/updated on: 2008-04-18
Geographic coverage: United States
Time period: 1997-01-01--1998-01-01
As a first step in understanding law enforcement agencies' use and knowledge of crime mapping, the Crime Mapping Research Center (CMRC) of the National Institute of Justice conducted a nationwide survey to determine which agencies were using geographic information systems (GIS), how they were using them, and, among agencies that were not using GIS, the reasons for that choice. Data were gathered using a survey instrument developed by National Institute of Justice staff, reviewed by practitioners and researchers with crime mapping knowledge, and approved by the Office of Management and Budget. The survey was mailed in March 1997 to a sample of law enforcement agencies in the United States. Surveys were accepted until May 1, 1998. Questions asked of all respondents included type of agency, population of community, number of personnel, types of crimes for which the agency kept incident-based records, types of crime analyses conducted, and whether the agency performed computerized crime mapping. Those agencies that reported using computerized crime mapping were asked which staff conducted the mapping, types of training their staff received in mapping, types of software and computers used, whether the agency used a global positioning system, types of data geocoded and mapped, types of spatial analyses performed and how often, use of hot spot analyses, how mapping results were used, how maps were maintained, whether the department kept an archive of geocoded data, what external data sources were used, whether the agency collaborated with other departments, what types of Department of Justice training would benefit the agency, what problems the agency had encountered in implementing mapping, and which external sources had funded crime mapping at the agency. Departments that reported no use of computerized crime mapping were asked why that was the case, whether they used electronic crime data, what types of software they used, and what types of Department of Justice training would benefit their agencies.
