Center for Disease Control: ATSDR Social Vulnerability Index

Every community must prepare for and respond to hazardous events, whether a natural disaster like a tornado or disease outbreak, or a human-made event such as a harmful chemical spill. A number of factors, including poverty, lack of access to transportation, and crowded housing may weaken a community’s ability to prevent human suffering and financial loss in a disaster. These factors are known as social vulnerability.

ATSDR created these databases, known as the Social Vulnerability Index (SVI),  to help emergency response planners and public health officials identify and map communities that will most likely need support before, during, and after a hazardous event. While this data is intended to be used to help public health officials prepare for a disaster, nonprofit organizations can use the data to identify potential regions that may be in need of particular services that nonprofit may be offering.

In addition to the downloadable databases, the CDC also provides an interactive CDC SVI Map to easily look at data by county.
