Magazine Audience

My magazine will mainly be aimed towards males but this doesn't mean it is not open for females.
It will be aimed mainly towards 15-30 year olds as for magazines such as Kerrang! which will have a similar audience to me, the mean age is 22 and has a very young audience. The target audience goes up to 30 as my magazine focuses on a more strange genre of music and therefore the audience may have to be more experienced music listeners, and the minimum target age is about 15 as music magazines popularly have a young audience and often you grow out of loving music and buying magazines after you have grown up.
