This study was designed to permit a "meta-evaluation" of the impact of alternative policing programs on social disorder. Examples of social disorder include bands of teenagers deserting school and congregating on street corners, solicitation by prostitutes and panhandlers, public drinking, vandalism, verbal harassment of women on the street, street violence, and open gambling and drug use. The data used in this study were taken from studies conducted between 1983 and 1990 in seven cities. For this collection, a common set of questions was identified and recoded into a consistent format across studies. The studies were conducted using similar sampling and interviewing procedures, and in almost every case used a quasi-experimental research design. For each target area studied, a different, matched area was designated as a comparison area where no new policing programs were begun. Surveys of residents were conducted in the target and comparison areas before the programs began (Wave I) and again after they had been in operation for a period ranging from ten months to two-and-a-half years (Wave II). The data contain information regarding police visibility and contact, encounters with police, victimization, fear and worry about crime, household protection and personal precautions, neighborhood conditions and problems, and demographic characteristics of respondents including race, marital status, employment status, education, sex, age, and income. The policing methods researched included community-oriented policing and traditional intensive enforcement programs.
