The National Officer-Involved Homicides Database (NOIHD) is a law-enforcement-wide database combining information on homicides resulting from all police actions (prior to booking) merged with crosswalks to law-enforcement agency- , demographic- , crime- , emergency department- , and gun-data. The database is aggregated at the level of law-enforcement agencies with annual measurement (2000-2017; n=641,821) suited for analysis of extant policy and/or policy changes that may be related to police-involved homicides in the United States.

New York Police Department (NYPD) Stop, Question, and Frisk Database, 2006 (ICPSR 21660)

Released/updated on: 2008-06-09
Geographic coverage: New York City, United States, New York (state)
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.
