But in a draft of a report to Congress requesting $139 billion in recovery funds, scheduled for official release on Thursday, the Puerto Rican government admits that 1,427 more people died in the last four months of 2017 compared with the same time frame in the previous year. The figures came from death registry statistics that were released in June, but which were never publicly acknowledged by officials on the island.

“Although the official death count from the Puerto Rico Department of Public Safety was initially 64, the toll appears to be much higher,” said the report, titled “Transformation and Innovation in the Wake of Devastation.”

In another section, it said: “According to initial reports, 64 lives were lost. That estimate was later revised to 1,427.”
