Scope of Study
Smallest Geographic Unit: United States
Geographic Coverage: United States
Date of Collection:
Universe: The universe for the 1999 SSLEA survey consists of agencies listed in the 1996 Directory Survey of Law Enforcement Agencies. The directory includes all state and local law enforcement agencies that are publicly funded and employ at least one full-time or part-time sworn officer with general arrest powers.
Data Types: survey data
Sample: For sampling purposes, the law enforcement agencies were separated into two groups: self-representing (SR) and non-self-representing (NSR) agencies. All state police or agencies with 100 or more sworn full-time equivalent (FTE) employees are SR. All remaining agencies in sheriff's department, local police, and special police categories are NSR.;
Mode of Data Collection: computer-assisted self interview (CASI), self-enumerated questionnaire
Extent of Processing: ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:
- Performed consistency checks.
- Checked for undocumented or out-of-range codes.
