The CPI https://hurricanemariasdead.com/index.html really took on a huge task on revealing the true count of deaths in the aftermath of Hurricane Maria, as authorities released low official numbers and as people continued to die throughout the months after the disaster.
They gathered data through surveys among the families with hurricane victims, compiled death certificates, funerary home notices and obtained official data from Puerto Rico authorities by suing the state to release the information. In this case the data served to find the characters in the story, to add context - by linking the hurricane to the causes of deaths - as well as to hold the government accountable - for its incorrect official statements, lack of inaction with regard to disaster response.
