A study published Tuesday in The New England Journal of Medicine estimates that nearly 6,000 people died in Puerto Rico after Hurricane María, with a survey indicating the mortality rate is likely more than 70 times the highly contested official death toll of 64.
Researchers with the Harvard T.H. Chan School of Public Health and Beth Israel Deaconess Medical Center surveyed thousands of survivors and initially estimated that at least 4,645 people died between when the storm struck the U.S. territory on September 20, 2017 and the end of the year.
However, considering that they could not survey people who lived alone and died due to the hurricane, researchers adjusted the estimate to 5,740. Citing the Centers for Disease Control and Prevention (CDC), the study says deaths can be attributed to the storm “if they are caused by forces related to the event, such as flying debris, or if they are caused by unsafe or unhealthy conditions resulting in injury, illness, or loss of necessary medical services.”
The findings bolster a series of damning independent reports that have disputed the official death toll. Pressure from those reports pushed Puerto Rico Gov. Ricardo Rosselló to recruit researchers from George Washington University to review the government’s process of accessing deaths tied to the hurricane and produce an analysis that is expected to be released in the coming weeks.
Pointing to that government-funded analysis, the Harvard study notes that its findings “will serve as an important independent comparison to official statistics from death-registry data, which are currently being reevaluated, and underscore the inattention of the U.S. government to the frail infrastructure of Puerto Rico.”
The hurricane decimated the island’s infrastructure, particularly its debt-riddenelectrical system. According to the National Hurricane Center (pdf), Maria caused an estimated $90 billion in damage, making it the third-costliest tropical storm since 1900, behind Katrina in 2005 and Harvey, which struck the Southern United States last year.
