A better comparison would be the same left column (causes of death, by %) and a similar right column: media coverage of these causes of death, by %, BUT only in media coverage which explicitly covers the cause of death as a cause of death, and not in another context.

Just because an article mentions terrorism doesn't mean that terrorism is being covered as a cause of death. Terrorism could be covered wrto. its economic impact.

Same with the flu. The article could be on vaccines.

All these causes of death have so many other newsworthy impacts, so a better comparison would exclude coverage of these causes in the context of their other impacts.

I don't think the general sentiment would necessarily be much different, though. You may very well find that "mass silent killers" get less airtime than other types of news.
