This study examined whether the introduction of a large number of off-premise alcohol outlets into a city over a brief period of time could affect rates of violent crime.
The study analysed annual counts of violent crime across 172 US Census block groups in Lubbock, Texas from 2006 through 2011. Spatial Poisson models related annual violent crime counts within each block group to off-premise and on-premise alcohol outlets active during this time period as well as neighbourhood socio-demographic characteristics. The effects of alcohol outlets were assessed both within block groups and across adjacent block groups.
On-premise outlets had a small, significant positive association with violence within a given block group. A similar well-supported local effect for off-premise outlets was not found. However, the spatially lagged effect for off-sale premises was well-supported, indicating that greater densities of these outlets were related to greater rates of violent crime in adjacent areas.
While these analyses confirmed a previous time-series analysis in finding no city-wide effect of the increase in off-premise outlets, they do suggest that such outlets in a local area may be related to violence in nearby geographic areas. They indicate the importance of examining neighbourhood-specific effects of alcohol outlets on violence in addition to the city-wide effects. They also present further evidence supporting the need to examine the differential effects of on-sale and off-sale premises.
本研究旨在探讨在短时间内大量引入非现场酒精销售点是否会影响暴力犯罪率。
本研究分析了 2006 年至 2011 年期间,德克萨斯州拉伯克市 172 个美国人口普查街区组的暴力犯罪年度计数。空间泊松模型将每个街区组内的年度暴力犯罪计数与同期活跃的非现场和现场酒精销售点以及邻里社会人口统计学特征联系起来。评估了酒精销售点在街区组内和相邻街区组之间的影响。
现场销售点与特定街区组内的暴力行为呈小而显著的正相关。没有发现非现场销售点存在类似的、有充分支持的局部效应。然而,非现场销售点的空间滞后效应得到了很好的支持,表明这些销售点的密度越大,相邻地区的暴力犯罪率就越高。
尽管这些分析证实了之前的时间序列分析发现非现场销售点增加对全市暴力犯罪没有影响,但它们确实表明,当地的这些销售点可能与附近地理区域的暴力行为有关。它们表明,除了全市范围的影响外,还需要检查酒精销售点对暴力行为的特定于邻里的影响。它们还提供了进一步的证据,支持需要检查现场和非现场销售点的差异影响。
