There are approximately 85 or fewer people killed and injured by tigers each year. These deaths and injuries are not all deliberate; many are accidental. The incidents involving death or injuries are reported together in the statistics, as reported by the BBC.
The reason for many of the human killings and injuries are due to rare incidents at zoos, or to the man-eating tigers in India. The man-eater tiger wanders outside of its usual habitat into an area where humans are. The tiger begins to stalk, then hunt humans to kill and eat them. This behavior is believed to be a direct result of the overwhelming success of India's conservation projects for tigers. These man-eater tigers tend to only exist in India, where the tiger population has grown rapidly from the conservation projects.
