CDC Social Vulnerability Index (SVI)

Social vulnerability refers to the resilience of communities when confronted by external stresses on human health, stresses such as natural or human-caused disasters, or disease outbreaks. Reducing social vulnerability can decrease both human suffering and economic loss. ATSDR's Social Vulnerability Index uses U.S. census variables at tract level to help local officials identify communities that may need support in preparing for hazards, or recovering from disaster.

社会脆弱性（Social vulnerability）指社区在面临危害人类健康的外部压力时的韧性，此类压力涵盖自然灾害、人为灾害或疾病暴发事件。降低社会脆弱性，既能减少人类苦难，也可降低经济损失。美国毒物与疾病登记署（ATSDR）的社会脆弱性指数（Social Vulnerability Index）采用美国人口普查分区（tract）级统计变量，助力地方官员甄别出需要获得支持以开展灾害防范或灾后恢复的社区。
