Although urbanization and population density predict levels of crime and disorder quite well, the amount of crime and disorder is not evenly distributed in urban environments. Rather, crime and disorder are concentrated to certain areas, places, and neighborhoods within these urban settings. Crime preventive efforts in these high-crime areas are thus of utter importance to reduce the overall amount of crime as well as fear of crime among the residents. The study at hand aims to evaluate the effects of such a crime preventive effort in high-crime, vulnerable urban neighborhoods in the city of Malmö, Sweden, through a community crime prevention program – Business Improvement District (BID, in Swedish Boende, Integration och Delaktighet). In this study, the BID-concept represents a collaboration among local property owners in conjunction with local agencies (e.g. city offices, the police, the fire and rescue service, etc.) acting under the motto“clean and safe” neighborhoods. Internationally, BID has been implemented world-wide with positive effects on crime and feelings of insecurity Sweden, showed positive effects on fear of crime among residents during a pre-post evaluation design, although the reported level of crime remained more or less unchanged. In this study, an extensive evaluation design is implemented where several sources of information (e.g. reported crimes, calls for emergency service, and neighborhood surveys) are applied to evaluate the effect of BID in treated areas, compared to matched control areas, using a pre-post equivalent area comparison design. The results of the study will provide local, as well as national, policy makers and practitioners with knowledge and evidence about community crime prevention efforts in urban vulnerable residential areas
