In this study, we set out to develop a new social vulnerability index (SVI). In doing so, we suggest some conceptual improvements that can be made to existing methodical approaches to assessing social vulnerability. To make the entanglement of socio-spatial inequalities visible, we are conducting a small-scale study on heterogeneous urban development in the city of Hamburg, Germany. This kind of high-resolution analysis was not previously available, but is increasingly requested by political decision makers. We can thus show hot spots of social vulnerability (SV) in Hamburg, considering the effects of social welfare, education, and age. In doing so, we defined SV as a contextual concept that follows the recent shift in discourse in line with the Intergovernmental Panel on Climate Change’s (IPCC) concepts of risk and vulnerability. Our SVI consists of two subcomponents: sensitivity and coping capacity. Populated areas of Hamburg were identified using satellite information and merged with the social data units of the city. Areas with high SVI are distributed over the entire city, notably in the district of Harburg and the Reiherstieg quarter in Wilhelmsburg near the Elbe, as well as in the densely populated inner city areas of Eimsbüttel and St. Pauli. As a map at a detailed scale, our SVI can be a useful tool to identify areas where the population is most vulnerable to climate-related hazards. We conclude that an enhanced understanding of urban social vulnerability is a prerequisite for urban risk management and urban resilience planning.

在这项研究中，我们着手开发一种新的社会脆弱性指数（SVI）。在此过程中，我们建议对现有的评估社会脆弱性的方法进行一些概念上的改进。为了让社会空间不平等的纠缠变得可见，我们正在德国汉堡市进行一项关于异质城市发展的小规模研究。这种高分辨率的分析以前是无法实现的，但政治决策者越来越需要这种分析。因此，考虑到社会福利、教育和年龄的影响，我们可以显示汉堡社会脆弱性（SV）的热点。在此过程中，我们将 SV 定义为一个背景概念，它遵循最近的话语转变，与政府间气候变化专门委员会 (IPCC) 的风险和脆弱性概念相一致。我们的 SVI 由两个子部分组成：敏感性和应对能力。使用卫星信息识别汉堡的人口稠密地区，并将其与该城市的社会数据单位合并。SVI高的区域分布在整个城市，特别是哈尔堡区和易北河附近威廉斯堡的Reiherstieg区，以及人口稠密的内城区艾姆斯比特尔和圣保利。作为详细比例的地图，我们的 SVI 可以成为确定人口最容易受到气候相关灾害影响的区域的有用工具。我们的结论是，加强对城市社会脆弱性的了解是城市风险管理和城市韧性规划的先决条件。
