随着城市规模、人口多样性和复杂性的不断增加，它们对未来灾害的脆弱性也将增加。本文探讨了132个城市地区之间的自然灾害脆弱性的变化，使用三个脆弱性指数：社会，建筑环境，灾害的影响。然后，本文研究了相对水平的脆弱性相比，联邦UASI资金。该文件表明，脆弱性表现为一个地方为基础的区域现象，与最脆弱的城市位于美国东部的相对重要性的基础相关的变化，从城市到城市在美国与社会脆弱性承担更大的重要性在南部和西南部，和建成环境脆弱性显示区域首要性的驱动指标之间的东北部和中西部城市。根据这一实证分析，新奥尔良是美国最脆弱的城市地区，但只得到了联邦政府提供的1%的准备资源。
As cities continue to increase in size, population diversity, and complexity their vulnerability to future disasters will increase as well. This paper explores the variability in vulnerability to natural hazards among the 132 urban areas using three indices of vulnerability: social, built environment, and hazard impact. The paper then examines the relative levels of vulnerability compared to federal UASI funding. The paper demonstrates that vulnerability manifests itself as a place-based regional phenomenon, with the most vulnerable cities located in the eastern half of the U.S. The relative importance of the underlying correlates changes from city to city across the United States with social vulnerability assuming greater importance in the South and Southwest, and built environment vulnerability showing regional primacy as the driving indicator among Northeastern and Midwestern cities. Based on this empirical analysis, New Orleans was the most vulnerable urban area in the U.S. yet received only one percent of the preparedness resources awarded by the federal government.
