Community Policing in Baltimore, 1986-1987 (ICPSR 9401)

Principal Investigator(s): Pate, Antony M.; Annan, Sampson O.


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.
