"Death is certain, the time is not": mortality and survival in Game of Thrones.

The mortality risk is high among characters in Game of Thrones. The probability of dying within the first hour after first appearing on screen was about 14%. By the end of the seventh season, more than half of the important characters had died, with violent deaths being the most common by far. The probability of survival was worse for characters who were male or lowborn, who had not switched allegiance during the show, and who featured more prominently. There is great potential for preventing violent deaths in the world of Game of Thrones.
