Social Vulnerability

Social vulnerability is the susceptibility of social groups to the adverse impacts of natural hazards, including disproportionate death, injury, loss, or disruption of livelihood.

As a consequence enhancing risk component of the National Risk Index, a Social Vulnerability score and rating represent the relative level of a community’s social vulnerability compared to all other communities at the same level. A community’s Social Vulnerability score is proportional to a community’s risk. A higher Social Vulnerability score results in a higher Risk Index score.
