More than 400 indirect deaths linked to LA wildfires, study suggests
- Researchers published a study on August 6, 2025, estimating that wildfires in Los Angeles from January 5 to February 1 caused about 440 deaths beyond the official toll.
- The study compared observed deaths during the fires to expected deaths from previous years, excluding 2020–2023 due to COVID-19 disruptions.
- The wildfires burned 152 square kilometers, destroyed thousands of structures, forced over 100,000 evacuations, and worsened health outcomes for people with lung and heart conditions.
- Boston University demographer Andrew Stokes said the 440 figure is a lower bound, reflecting excess deaths from smoke exposure, healthcare delays, and mental health impacts.
- The findings highlight the need for improved health tracking and sustained support after wildfires to address both direct and indirect mortality caused by climate emergencies.
