This study investigated correlates of outdoor advertising panel density in predominantly African American neighborhoods in New York City. Research shows that black neighborhoods have more outdoor advertising space than white neighborhoods, and these spaces disproportionately market alcohol and tobacco advertisements. Thus, understanding the factors associated with outdoor advertising panel density has important implications for public health. We linked 2000 census data with property data at the census block group level to investigate two neighborhood-level determinants of ad density: income level and physical decay. Results showed that block groups were exposed to an average of four ad spaces per 1,000 residents and that vacant lot square footage was a significant positive predictor of ad density. An inverse relationship between median household income and ad density did not reach significance, suggesting that relative affluence did not protect black neighborhoods from being targeted for outdoor advertisements.
本研究调查了纽约市以非裔美国人为主的社区中户外广告面板密度的相关因素。研究表明,黑人社区比白人社区拥有更多的户外广告空间,并且这些空间中酒精和烟草广告的比例过高。因此,了解与户外广告面板密度相关的因素对公共卫生具有重要意义。我们将2000年的人口普查数据与普查街区组层面的房产数据相联系,以调查广告密度的两个社区层面的决定因素:收入水平和物质衰败。结果显示,每1000名居民平均接触到4个广告空间,空地平方英尺数是广告密度的一个显著正向预测指标。家庭收入中位数与广告密度之间的负相关关系未达到显著水平,这表明相对富裕并不能保护黑人社区不被作为户外广告的目标。
