There has been increasing recognition that there is a fundamental spatial component to most social phenomena, including health-related behaviors and outcomes. Health geographics has begun to develop as a significant sub-discipline within geography, and is strongly influenced by both spatial statistics and medical science. The goal of this field is to increase understanding of the spatial processes underlying health patterns, and thereby contribute to policies for encouraging healthy behavior, and mitigating both individual and public health risks. Unfortunately, the potential contributions to alcohol policy have yet to be comprehensively integrated into health geographics. This article presents a review of potential methodological contributions to alcohol policy by demonstrating the use of geographic information systems techniques and spatial statistics on a dataset comprised of alcohol-related arrest information. A wide range of outcomes are illustrated, from descriptive spatial statistics of alcohol-related behavior, to correlative analyses between sources of alcohol and alcohol arrests, and including inferential analyses regarding factors influencing alcohol-related outcomes. All of these are accompanied by suggestions regarding how policymakers can use the results in developing new policy responses or refining existing ones. Suggestions for the future directions of spatially informed alcohol policy are provided.KEY WORDS: geographic information systems, health geography, alcohol policy, spatial statistics
IntroductionThere has been increasing recognition that there is a fundamental spatial component to most social phenomena, including health-related behaviors and outcomes. Health geographics has begun to develop as a significant sub-discipline within geography, and is strongly influenced by both spatial statistics and medical science. The goal of this field is to increase understanding of the spatial processes underlying health patterns, and thereby contribute to policies for encouraging healthy behavior, and mitigating both individual and public health risks. Unfortunately, the potential contributions to alcohol policy have yet to be comprehensively integrated into health geographics. This article presents a review World Medical & Health Policy, Vol. 6, No. 3, 2014 242 1948-4682 # 2014 of potential methodological contributions to alcohol policy by demonstrating the use of geographic information systems techniques and spatial statistics on a dataset comprised of alcohol-related arrest information.In the following section, the extant literature regarding the use of spatial statistics in health and alcohol-related behavior is reviewed. This is followed by a detailed description of a dataset of alcohol-related arrests provided by the Metropolitan Police Department of Washington, DC, and a range of supporting spatial datasets that are used in the analyses of the arrest data. A wide range of outcomes are illustrated, from descriptive spatial statistics of alcohol-related behavior, to correlative analyses betw...
