Police Public Contact Survey represents a second stage in the development of a recurring statistical collection on citizen contact with the police. The Police Public Contact Survey was designed to address the mandate set forth by the Violent Crime Control and Law Enforcement Act of 1994 to collect, evaluate, and publish data on the use of excessive force by law enforcement personnel. Between July 1, 1999 and December 31, 1999, BJS conducted the nationwide police public contact survey of approximately 90,000 persons aged 16 or older to learn about their contacts with the police utilizing an updated and improved version of the instrument field-tested in May 1996. Results of the first pilot test were reported in Police Use of Force: Collection of National Data, November 1997, NCJ 165040. The 1999 questionnaire captures more detailed information about the nature of the police citizen contact, respondent perceptions as to whether any force encountered was excessive, and any provocative actions which may have been initiated by the respondent during the encounter with police. In addition, the instrument includes a new section designed to gather information on police-initiated stops for routine traffic violations.

State Police Traffic Stop Data Collection Procedures collected data from the Nation's 49 State law enforcement agencies with traffic patrol responsibility about their policies for recording race and ethnicity data for persons in traffic stops. The questionnaire, mailed out in March 2001, obtained basic information on the circumstances under which demographic data were collected for traffic-related stops and whether this information was stored in an electronically accessible format. The data collection was not designed to obtain available agency databases containing traffic-stop records.

The Census of Publicly Funded Forensic Crime Laboratories collects data on staff, budgets, operating procedures, case workloads, training, and resource needs from among the Nation's more than 300 crime labs. This Bureau of Justice Statistics census represents the first national census of crime labs. Census information will be used to better understand the number of cases processed by these labs and the amount of resources required to meet the increased demand for forensic services. In developing and implementing this census, BJS worked closely with the American Society of Crime Laboratory Directors (ASCLAD).
