There seems often to be an implicit assumption in the minds of many people that most trolls are children or teenagers or generally in the younger demographics.
Such as this unsourced claim on this article:
Close to 90 percent of the trolls on the Internet are between the ages of 14 to 21
Also in one of the quotation for this article
These trolls are predominantly young white men
Also in one of the responses to this YA question:
Many are pre-teens and adolescents.
and from the same post, the (most likely made up) statistics claimed by user ILLUMINUTTY:
13 - 14 : 12% 15 - 19 : 43% 20 - 26 : 22% 26 - 33 : 14% 34 and older : 9%
Also the title of this article:
What is turning so many young men into internet trolls?
Is there any sort of truth to this? Is there any evidence that shows the demographic of trolls to be any different than the demographic of normal internet users (esp. age; race, gender, and economic status are also interesting topics to discuss but please focus this question on age)? Is young internet users more predisposed to trolling than older people?
