The research led by Harvard University was published online in the New England Journal of Medicine. Hurricane season begins Friday.
The official death toll is 64.
Understanding the true number of deaths due to Hurricane Maria is important for a number of reasons.
Earlier this year, researchers surveyed 3,299 randomly selected households (of more than 1.1 million) across the United States territory about displacement, infrastructure loss, and causes of death. Respondents were also asked about deaths within a 5-minute walking distance of their homes.
Katrina's final death toll stood at 18 hundred 33.
The researchers noted there was a high mortality rate after Hurricane Maria devastated the island in September 2017.
But the estimate isn't as precise as the figure implies.The researchers calculate a statistical term called a 95 percent confidence interval, which encompasses a broad range - from 800 to 8,500 deaths.
Puerto Rico's government released a statement on Tuesday welcoming the study and saying it would analyze it further.

A real change needs to take place in this industry, and such incidents should not happen, the woman wrote on her Twitter account. She also said that following his orgasms he handed the flight attendant his used napkins to dispose of.
And as many did not realize how many died from hurricane Maria, Gonzalez says many don't realize how many on the island still need help. The team was eager to suggest that Puerto Rico's government could use their methodology at an even larger scale, and minimize the uncertainties and reduce the wide range of potential deaths to a more stable one. Researchers wrote that they hope US officials will use the data to better determine the scale and severity of disasters and prepare for recovery.
By definition, this could be either forces related to the event such as flying debris, or unsafe or unhealthy conditions in the three months afterward, including loss of necessary medical services. It also notes that Puerto Rican officials have refused to make public basic mortality statistics.
The experts said that an accurate count was complicated by the widespread devastation wreaked by the storm.
The Federal Emergency Management Agency, or FEMA, has approved billion in individual assistance grants for residents of Puerto Rico. A CNN survey of funeral directors found 499 additional deaths.
During the storm itself, residents might be hit by flying debris or swept away in flash floods. There is no evidence of such, but that many more lives potentially could have been lost locally in the record-setting storm seems obvious. And hurricane-related deaths appear to have continued for months after the September hurricane.
The report was published as Puerto Rico Gov. Ricardo Rossello hosted a conference on disaster prevention and management.
The new study adds to "the growing consensus that the deaths have been undercounted", Santos said.
While valuable in exposing the absurd official government count, these previous studies were extremely limited in the type of data they were able to collect. "It's infuriating, that's the bottom line". In fact, the Harvard team says its results are "likely to be an underestimate" because of this bias. Still, "The way this is done, by interviews with people in different barrios in Puerto Rico, it seems to me that someone could report a death as associated with the hurricane when it was not"..
