社区基础设施，如人行道、医疗设施、公共交通、社区聚会场所和树冠，为安全、健康和有弹性的社区提供了必要的支持。本文研究了社区基础设施的存在和状况，并表明存在“基础设施沙漠”，这是低收入社区的基础设施明显不足。一个通用的数据驱动的框架，开发和实施在街道一级的12种类型的社区基础设施在得克萨斯州的达拉斯。结果显示，大多数类型的基础设施在收入水平上存在显著的基础设施不平等。统计推断预测（95%置信度），低收入社区基础设施严重不足（8种或更多基础设施不足类型）的可能性是高收入地区的2.0至3.5倍，而基础设施严重不足的可能性是中等收入社区的1.4至2.4倍。本文件探讨了在考虑多种基础设施类型方面所面临的方法学挑战，并为基础设施投资的优先排序提供了指导。
Neighborhood infrastructure, such as sidewalks, medical facilities, public transit, community gathering places, and tree canopy, provides essential support for safe, healthy, and resilient communities. This paper examines the presence and condition of neighborhood infrastructure and shows that “infrastructure deserts” exist, which are low-income neighborhoods with significantly more deficient infrastructure. A generalized data-driven framework is developed and implemented at the street-level for 12 types of neighborhood infrastructure in Dallas, Texas. The results show significant infrastructure inequities across income levels for most types of infrastructure. Statistical inference predicts (with 95 % confidence) that low-income neighborhoods are 2.0 to 3.5 times more likely to have highly deficient infrastructure (8 or more deficient infrastructure types) than high-income areas and 1.4 to 2.4 times more likely to have highly deficient infrastructure than middle-income neighborhoods. This paper addresses the methodological challenge of considering multiple infrastructure types and provides a guide for infrastructure investment prioritization.
