Mapping Social Vulnerability to Climate Change in California

The map on this page shows the modified Social Vulnerability Index for Census Tracts in California. This index was created by researchers at the Pacific Institute to better understand Californians’ social vulnerability to climate change-related impacts, such as natural disasters or increased heat stress. Vulnerability is defined as the susceptibility of a population to harm from exposure to a hazard, and its ability to prepare for, respond to, and recover from hazards.
