Relative coverage of causes of death in The Guardian newspaper, 1999 to 2016

Relative coverage of articles mentioning the top 10 causes of death in the USA (in addition to terrorism, homicide and drug overdoses) in The Guardian newspaper.
This is based on the number of articles which mention any of the terms or synonym/related terms (e.g. 'murder' for homicide) in the headline or body text. This is
normalized to the relative share by dividing by the total number of articles which feature any of these causes of death.
