A current preprint by Alexis R. Santos-Lozada and Jeffrey T. Howard concludes that
The mortality burden might [be] larger than official counts, and will exceed the present official demise toll by an element of 10.
The authors used month-to-month demise data from the Puerto Rico Important Statistics system from 2010 to 2016. Though information for 2017 was apparently not obtainable, they extracted information from an announcement made by Héctor Pesquera, the Secretary of Public Security:
The variety of deaths for September 2017 is 2,838, with 95% of the deaths processed by the Puerto Rico Division of Well being.”
Their remaining conclusions depend on assumptions and methodology wanted to foretell October figures. However simply by trying on the information, we will see that the official determine of 55 deaths seems to be approach off.
To create this plot, I downloaded the Microsoft Phrase model of the preprint, transformed it to PDF, then scraped the information from Desk 1. As a result of there’s month-to-month variability in complete deaths in Puerto Rico, I computed the distinction between every information level and the typical for his or her respective month. The September 2017 information level is a transparent outlier, 455 deaths above common, and is nicely past 55 deaths above the most important deviation from the month-to-month common. Understand that Hurricane María hit Puerto Rico on September 20th, so solely 10 days account for the noticed distinction. The official determine contains September and October so it covers at the least 40 days.
Under is a plot of the overall deaths, which the preprint exhibits in Determine 2.
Notice that 55 was the official determine on the time the preprint was written.
