This study was designed to analyze the impact of four televised public service announcements (PSAs) aired for three months in Lima, Ohio. The researchers sought to answer three specific research questions: (1) Were the PSAs effective in transferring knowledge to citizens about the police? (2) Did the PSAs have an impact on resident satisfaction with the police? and (3) Did the PSAs have an impact on the behavior of citizens interacting with the police? To assess public attitudes about the Lima police and to determine whether the substance of the PSAs was being communicated to the residents of Lima, three waves of telephone interviews were conducted (Part 1). The first telephone interviews were conducted in April 1996 with approximately 500 randomly selected Lima residents. These were baseline interviews that took place before the PSAs aired. The survey instrument used in the first interview assessed resident satisfaction with the police and the services they provided. After completion of the Wave 1 interviews, the PSAs were aired on television for three months (June 5-August 28, 1996). After August 28, the PSAs were removed from general circulation. A second wave of telephone interviews was conducted in September 1996 with a different group of randomly selected Lima residents. The same survey instrument used during the first interviews was administered during the second wave, with additional questions added relating to whether the respondent saw any of the PSAs. A third group of randomly selected Lima residents was contacted via the telephone in January 1997 for the final wave of interviews. The final interviews utilized the identical survey instrument used during Wave 2. The focus of this follow-up survey was on citizen retention, over time, of the information communicated in the PSAs. Official data collected from computerized records maintained by the Lima Police Department were also collected to monitor changes in citizen behavior (Part 2). The records data span 127 weeks, from January 1, 1995, to June 7, 1997, which includes 74 weeks of pre-PSA data and 53 weeks of data for the period during the initial airing of the first PSA and thereafter. Variables in Part 1 include whether respondents were interested in learning about what to do if stopped by the police, what actions they had displayed when stopped by the police, if they would defend another person being treated unfairly by the police, how responsible they felt (as a citizen) in preventing crimes, the likelihood of calling the police if they were aware of a crime, perception of crime and fear of crime, and whether there had been an increase or decrease in the level of crime in their neighborhoods. Respondents were also asked about the amount of television they watched, whether they saw any of the public service announcements and if so to rate them, whether the PSAs provided information not already known, whether any of the PSA topics had come up in conversations with family or friends, and whether the respondent would like to see more PSAs in the future. Finally, respondents were asked whether the police were doing as much as they could to make the neighborhood safe, how responsive the police were to nonemergency matters, and to rate their overall satisfaction with the Lima Police Department and its various services. Demographic variables for Part 1 include the race, gender, age, marital status, level of education, employment status, and income level of each respondent. Variables in Part 2 cover police use-of-force or resisting arrest incidents that took place during the study period, whether the PSA aired during the week in which a use-of-force or resisting arrest incident took place, the number of supplemental police use-of-force reports that were made, and the number of resisting arrest charges made.

This study surveyed police chiefs and data analysts in order to determine the use of data in police departments. The surveys were sent to 1,379 police agencies serving populations of at least 25,000. The survey sample for this study was selected from the 2000 Law Enforcement Management and Administrative Statistics (LEMAS) survey. All police agencies serving populations of at least 25,000 were selected from the LEMAS database for inclusion. Separate surveys were sent for completion by police chiefs and data analysts. Surveys were used to gather information on data sharing and integration efforts to identify the needs and capacities for data usage in local law enforcement agencies. The police chief surveys focused on five main areas of interest: use of data, personnel response to data collection, the collection and reporting of incident-based data, sharing data, and the providing of statistics to the community and media. Like the police chief surveys, the data analyst surveys focused on five main areas of interest: use of data, agency structures and resources, data for strategies, data sharing and outside assistance, and incident-based data. The final total of police chief surveys included in the study is 790, while 752 data analyst responses are included.

The primary objective of this study was to formulate evidence-based lessons on recruitment, retention, and managing workforce profiles in large, United States police departments. The research team conducted a national survey of all United States municipal police agencies that had at least 300 sworn officers and were listed in the 2007 National Directory of Law Enforcement Administrators. The survey instrument was developed based on the research team's experience in working with large personnel systems, instruments used in previous police staffing surveys, and discussions with police practitioners. The research team distributed the initial surveys on February 27, 2008. To ensure an acceptable response rate, the principal investigators developed a comprehensive nonresponse protocol, provided ample field time for departments to compile information and respond, and provided significant one-on-one technical assistance to agencies as they completed the survey. In all, the surveys were in the field for 38 weeks. Respondents were asked to consult their agency's records in order to provide information about their agency's experience with recruiting, hiring, and retaining officers for 2006 and 2007. Of the 146 departments contacted, 107 completed the survey. The police recruitment and retention survey data were supplemented with data on each jurisdiction from the American Community Survey conducted by the United States Census Bureau, the Bureau of Labor Statistics, and the Federal Bureau of Investigation Uniform Crime Reports. The dataset contains a total of 535 variables pertaining to recruitment, hiring, union activity, compensation rates, promotion, retirement, and attrition. Many of these variables are available by rank, sex and race.

In 1996, the Bureau of Justice Statistics sponsored a pretest of a survey instrument designed to compile data on citizen contacts with police, including contacts in which police use force. The survey, which involved interviews (both face-to-face and by phone) carried out by the United States Census Bureau, was conducted as a special supplement to the National Crime Victimization Survey (NCVS), an ongoing household survey of the American public that elicits information concerning recent crime victimization experiences. Questions asked in the supplement covered reasons for contact with police officer(s), characteristics of the officer, weapons used by the officer, whether there were any injuries involved in the confrontation between the household member and the officer, whether drugs were involved in the incident, type of offense the respondent was charged with, and whether any citizen action was taken. Demographic variables include race, sex, and age.

For this study, two different projects with an overlap of purpose made use of the same data, which were based on a national sample of 695 police departments. One project conducted background research for a guidebook on call management for community policing. The other focused on the use of computer-aided dispatch (CAD) systems in community policing. Survey questions focused on the types of CAD systems, call management strategies, and community policing activities employed by each of the departments. Variables include types of CAD data used, use of different call management strategies, problem solving measures used, resource allocation measures used, community involvement/satisfaction measures used, support for special units, methods used for management accountability, and involvement in community policing activities.
