My target audience

By using Demographics and Psychographics i have decided on the age, gender and SEG for my magazine, as the genre im aiming for is rock/metal i need to target an audience who's primary genre is also that, as most people that like rock/metal are usually young from ages 15-20 thats the age im targeting. Although people would argue that this genre is more for the male audience i am going to terget both genres, as from my experience i know a lot of girls that read rock magazines and also enjoy the music. Being stereotypical it is common that people that wear dark clothes, have a lot of piercings and tattoo's are most likely to read this magazine. In statistics it is very unlikely that high class people from A-B would not read this magazine and so im aiming for a SEG of C2-E, as the magazine is going to cheap these people can afford it.
