CDC Social Vulnerability Index 2014

This is the Social Vulnerability Index (SVI) developed by the U.S. Centers for Disease Control (CDC) Agency for Toxic Substances and Disease Registry (ATSDR) [1]. This is often used by the emergency response community to anticipate areas where social support systems are weaker, and residents may be more likely to need help. A map viewer for the national database can be found here [2].

November 2023 updates: at the time of Hurricane Harvey, the latest SVI was based on 2014 census data. The CDC SVI website and feature services have since changed. See the current (updated) links for more details.

Subsets of CDC's 2014 SVI for the Hurricane Harvey and Hurricane Irma hydrologic study areas can be downloaded from the contents list below.

本数据集为美国疾病控制与预防中心（Centers for Disease Control and Prevention, CDC）下属的有毒物质与疾病登记署（Agency for Toxic Substances and Disease Registry, ATSDR）开发的社交脆弱性指数（Social Vulnerability Index, SVI）。该指数常被应急响应领域用于预测社会支持系统较为薄弱的区域，居民在这些区域可能更需要援助。国家数据库的地图查看器可在此处找到[2]。

截至2023年11月更新：在哈维飓风发生时，最新的SVI基于2014年的普查数据。CDC的SVI网站和功能服务已有所变更。请参阅当前（更新后）的链接以获取更多详细信息。
