VA CDC SVI BlockGroup 2020

Overall Social Vulnerability at Census Block Group based on the following 4 themes: Socioeconomic, Household Composition, Minority Status and language, Housing Type and Transportation.

Percentile ranking values range from 0 to 1, with higher values indicating greater social vulnerability.

Every community must prepare for and respond to hazardous events, whether a natural disaster like a tornado or a disease outbreak, or an anthropogenic event such as a harmful chemical spill. The degree to which a community exhibits certain social conditions, including high poverty, low percentage of vehicle access, or crowded households, among others, may affect that community’s ability to prevent human suffering and financial loss in the event of a disaster. These factors describe a community’s social vulnerability.
