Audience for preliminary task

The target audience I have chosen is 16-18 year olds because that is the majority age range of students that attend Wyke college, and also it will be easier for me to appeal to that age range seeing as I am sixteen myself; I know what interests people in that age group so I can anchor them in. Also, it wouldn't fit the concept if my magazine if I based it on college and used people who were in their mid forties.
