I'm not really qualified to answer that question. Though, I think a fair amount of it depends on definitions. If you include news adjacent talking heads and news-themed youtubers there'd be quite a few. After all, most nations have national and regional government mouthpieces. Then you have major cities and their newspapers, radio stations, and TV news. Even third world places have at least newspapers and radio stations.

But, yeah, journalist isn't nearly as common as construction workers or miners.

I do think that government and organized crime murders of journalists are substantially worse on a pound by pound comparison. It was just happening less often than I had previously assumed.
