A review of the impacts of Business Improvement Districts on crime and disorder

Abstract

Business Improvement Districts (BIDs) are an initiative adopted by some local governments, businesses, and residents to address concerns around crime and disorder in commercial areas, especially open street town centres. BIDs have become popular in the USA since the 1970s; however, no comprehensive review of evaluations has occurred to date. This paper systematically reviewed the academic literature to find 13 BID evaluations. These studies were examined in terms of their impacts on crime and disorder, displacement, and cost-effectiveness. Of the nine studies that quantitatively examined BID impacts on crime rates, eight (88%) found a reduction in one or more crime types. Six studies explored BID impacts on property crime, with all finding BIDs had a significant negative association with at least one type of property crime, with BIDs particularly effective at targeting vehicle-related offences. BIDs were also found to have a positive impact on reducing disorder and public nuisance type offences, however, had mixed evidence on violent crime, with three out of seven studies on violent crime finding BIDs can help to prevent robbery. Displacement of crime to surrounding areas was found to be rare, and the three studies that examined costs of operating BIDs all concluded they are cost-effective. The challenges of implementing BIDs are discussed, along with the implications for ongoing policy and practice development in the reduction of crime and disorder in commercial areas.
