The proposed addition to the US census of a question regarding the legal status of census respondents poses a major problem for both vulnerability researchers and the vulnerable undocumented immigrant community. Vulnerability scholar and PhD student, Jason Sauer, discusses how the change to the census may interfere with efforts to identify vulnerable communities, and may stymie efforts to make these undocumented communities more resilient to extreme weather events and climate change. He also interviews Masavi Parea of Chispa, an organization advocating for resilience and environmental justice in Phoenix, about his own history as a formerly undocumented immigrant, the ways the undocumented community and Latinos are systematically made vulnerable, and what organizations like Chispa are doing to increase community resilience.
