Community Policing in Baltimore, 1986-1987

This data collection was designed to investigate the effects of foot patrol and ombudsman policing on perceptions of the incidence of crime and community policing practices in Baltimore, Maryland. Data collected at Wave 1 measured perceptions of crime and community policing practices before the two new policing programs were introduced. Follow-up data for Wave 2 were collected approximately one year later and were designed to measure the effects of the new policing practices. Included in the data collection instrument were questions on the perceived incidence of various crimes, police effectiveness and presence, disorder, property and personal crime and the likelihood of crime in general, feelings of safety, crime avoidance behaviors and the use of crime prevention devices, cohesion and satisfaction with neighborhoods, and awareness of victimization and victimization history. The instrument also included demographic questions on employment, education, race, and income.本数据集旨在探究美国马里兰州巴尔的摩市中，徒步巡逻（foot patrol）与警务申诉专员制度（ombudsman policing）两种新型警务模式对民众犯罪发生率认知与社区警务实践观感的影响。第一波（Wave 1）数据采集于两项新型警务计划正式推行前，用于测量民众对犯罪状况与社区警务实践的初始认知；约一年后采集的第二波（Wave 2）跟踪数据，则用于评估新型警务实践的实施效果。本次调研问卷涵盖多类问题，涉及各类犯罪的感知发生率、警方执法效能与出勤存在感、社区乱象、财产与人身犯罪情况、整体犯罪发生概率、民众安全感、避罪行为与防罪设备使用情况、社区凝聚力与邻里满意度，以及受害经历知晓度与既往受害史。此外，问卷还包含就业、学历、种族与收入等人口统计学相关问题。
