"To be honest, I was seeing these maps about a year ago," [Boscoe] tells Shots. One he points to is a state-by-state map of distinctive musical artists based on the online listening habits of people across the country. In other words, which artist was listened to far more often in one state than the others.
"I wondered what it would look like if you applied this to something more serious, like mortality data," he says. He took advantage of a standardized list of causes of death — 113 in all — that are used across the country and a national database of the underlying causes of death collected between 2001 to 2010.
Boscoe calculated the mortality rates for all 113 causes of death in each state and compared them with the rates for the same causes nationwide. On the map, each state and Washington, D.C., then got labeled with the local cause that was, essentially, the largest multiple of the corresponding national rate.
