A recent study suggests that wildfires in Los Angeles this year, which devastated neighborhoods and forced thousands to evacuate, may have resulted in a significant number of unreported deaths. The fires, specifically the Palisades and Eaton blazes, were officially linked to at least 30 fatalities. However, researchers believe they may be connected to an additional 410 deaths during the period from January 5 to February 1, leading to a total of 440 wildfire-related deaths.
The study notes that these additional fatalities likely stem from various issues, including increased exposure to poor air quality and interruptions in healthcare access. Andrew Stokes, a mortality demographer and a key author of the study, was motivated by the experiences of friends and family affected by the fires to explore the numbers further.
Stokes, an associate professor at Boston University, expressed that his personal connections led him to apply his expertise to the situation and assess the true impact of the wildfires on mortality rates.
The findings underscore the need to recognize how deadly wildfires can be beyond direct casualties. Experts emphasize that such crises can have lingering health effects extending far beyond the immediate disaster.
In the past, Stokes assessed excess deaths during the pandemic when many fatalities were unrecorded. He adapted that understanding to investigate the mortality burden resulting from events like the Los Angeles wildfires.
The study accounted for not just direct wildfire-related deaths, but also conditions worsened by the fires, such as lung or heart diseases, along with mental health issues caused by the stress of the situation.
To carry out this research, the team compared death records in Los Angeles County during January and February against figures from other years, excluding the pandemic years of 2020-2023. This comparison helped estimate how many deaths might have occurred without the wildfires.
They calculated excess deaths by examining the difference between actual and expected mortality figures. According to the study, more than 6,300 deaths were recorded in the county during this period, compared to about 5,900 expected deaths, indicating that nearly 7% of the reported deaths were excess fatalities tied to the wildfires.
Stokes expressed surprise at the severity of the underreported data, stating, “The magnitude of the underreporting in the official data is just very severe.” He hopes that shining a light on these excess deaths could lead to increased support for those still dealing with the aftermath.
The researchers caution that the data is preliminary and that the number of excess deaths could potentially rise. “That 440 value that we estimate is clearly the lower bound, because we only look at the first weeks after the wildfire started,” Stokes added, indicating concerns about long-term health effects as individuals develop wildfire-related illnesses.
Moving forward, the researchers suggest that future studies should focus on the longer-term health ramifications of the wildfires and the specific causes of these excess mortality rates.
