New York Police Department (NYPD) Stop, Question, and Frisk Database, 2006 (ICPSR 21660)
These data were originally collected by New York Police Department officers and record information gathered as a result of stop question and frisk (SQF) encounters during 2006. These data were used in a study carried out, under contract to the New York City Police Foundation, by the Rand Corporation's Center on Quality Policing. The release of the study, "Analysis of Racial Disparities in the New York Police Department's Stop, Question, and Frisk Practices" (Rand Document TR-534-NYCPF, 2007) generated interest in making the data available for secondary analysis. This data collection contains information on the officer's reasons for initiating a stop, whether the stop led to a summons or arrest, demographic information for the person stopped, and the suspected criminal behavior.
The public-use data files in this collection are available for access by the general public. Access does not require affiliation with an ICPSR member institution.

- New York City Police Department
- United States Department of Justice. Office of Justice Programs. Bureau of Justice Statistics
Scope of Study
At the request of the NYPD, several variables were removed from the original data file. These variables reflected notes made by NYPD officers during stop-question-frisk encounters, and thus contained potentially identifying information about officers and suspects.
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.
Restrictions: This data collection may not be used for any purpose other than statistical reporting and analysis. Use of these data to learn the identity of any person or establishment is prohibited.
