(CNN) — Puerto Rico’s governor says he’s revising the official death toll from Hurricane Maria in the wake of a report from George Washington University that estimated the storm caused 2,975 deaths. “Even though it is an estimate, we are officially changing, or we are putting an official number to the death toll,” Gov. Ricardo Rossello told reporters Tuesday. “We will take the 2,975 number as the official estimate for the excess deaths as a product of Maria.”
Rossello acknowledged that the 2,975 statistic is only an estimate, and not a concrete list of names. Moving forward, he said, officials will continue to investigate deaths from the storm and refine the official tally.
“This is an approximation, a scientific study where the deaths are estimated. We don’t have the names,” Rossello said. “That is something that will take place throughout this process. And this number can change. It could be less, it could be more, as time passes,” he said.
It could take months or years, he said, to come up with a complete list of storm-related deaths.
“We are using the best science available … to be able to give a sense of closure to all of this,” he said. “The truth is there is a lot of work to do.”

Hurricane Maria caused an estimated 2,975 deaths in Puerto Rico, according to a new report from George Washington University — 46 times more than the official toll given by the Puerto Rican government.
Researchers calculated excess deaths that occurred in the US commonwealth between September 2017 and February.
The study was commissioned by the Puerto Rican government after the September 2017 storm.
The latest estimated death toll is far higher than the current official toll of 64.
A key unanswered question: Will the Puerto Rican government now revise its official tally as a result?
Another uncertainty: Will this new study, conducted at the request of Puerto Rican officials, provide any closure to families who’ve long argued their loved ones died because of the storm, but haven’t received any official acknowledgment?
The official Hurricane Maria toll matters in part because families of those who died in the aftermath of the storm are eligible to have some funeral expenses covered by the US government. Experts say higher death tolls drive more disaster aid. And knowing precisely how and why people died can help authorities prevent future hurricane-related deaths.
The George Washington University report, released to the public Tuesday, follows a number of others like it.
The Puerto Rican government also quietly admitted the official toll was higher recently. In a report to Congress earlier this month, the US commonwealth said documents show that 1,427 more deaths occurred in the four months after the storm than “normal,” compared with deaths that occurred the previous four years. That figure also appeared in a draft of the report published and opened for public comment in July.
Researchers behind George Washington University’s study said they felt they were able to provide a more accurate estimate because they took into account additional factors such as migration.
“I do think this study helps to validate that sense that many people had that there were just too many deaths,” said Lynn Goldman, dean of the university’s Milken Institute School of Public Health.
But she also stressed that Tuesday’s report marks only the first phase of the study.
“In the next phase, we would like to dig down deeper into that number to understand among all the deaths that occurred, which of them were related to Hurricane Maria, which of them would not have occurred if it hadn’t been for the storm? We’re not able to say that now,” Goldman said.
She acknowledged that a complete list may never be possible.
“At the end of the day,” she said, “we may never be able to fully identify all those 2,975 people.”
‘We are not going to revive them’
With many different estimates emerging, it’s hard to know who to believe, said Lourdes Rodriguez, whose father, Natalio, died in January.
“This is up and down numbers. No one knows how or from what (source) is the real number,” Rodriguez said. “Due to the island being shut down there was no way of knowing anything for a week or week and a half after the event.”
Natalio Rodriguez’s death hasn’t been officially classified as related to the storm, but his family believes Maria was to blame. He died after the generator that was running his breathing machine ran out of gas.
And no study, Lourdes Rodriguez said, can make up for what she and so many other lost.
“We are not going to revive them, unfortunately. We just have to be prepared or get prepared for the next event,” Rodriguez said. “September is one of the hottest months of the year, and you see people going to the beach and living in ‘la la land’ as if nothing is going to come.”
CNN and other news organizations have been raising questions about the official Hurricane Maria death toll for months. In November, CNN reporters surveyed 112 funeral homes across the island, about half the total. Reporters found that funeral home directors identified 499 deaths they considered to be hurricane-related. In December, The New York Times estimated 1,052 “excess deaths” occurred after Maria. Others produced similar estimates.
A research letter published this month in the medical journal JAMA estimated that between 1,006 and 1,272 people died in connection to the storm.
In May, a team that included researchers from Harvard University published a study in the New England Journal of Medicine estimating that 793 to 8,498 people died in Maria’s wake, a range that some academics have criticized as overly broad. The study’s midpoint estimate — 4,645 deaths — became a rallying cry for activists upset by what they see as a lack of accountability for the scale of the catastrophe by officials in Puerto Rico and the United States.
This year, CNN and the Centro de Periodismo Investigativo (CPI) in Puerto Rico sued the island’s Demographic Registry to make public a database with information about everyone who died in the months after the storm.
Using the same database, CNN reported on deaths labeled in government records as hurricane-related that were not counted by officials; and, in partnership with CPI, reported on an apparent leptospirosis “outbreak” that was not identified as an outbreak by authorities.
The network also created an online database the public can use to search for the names of all the people who died in the months after the storm — and tell reporters about deaths that may have been related to Maria.
