Using media theory to discuss target audience

The target audience for my music magazine are teenagers from the age 16-19. In my magazine their will be music, fashion and gossip about the artist because this will appeal to my target audince and my targeted gender, females. Even though my magazine is targeted to females i don't think this would affect the sales figure because their is alot of magazine targeted to males alone. I also thought about the socio-economic, and the target audience would either working or going to college and would be able to have thier own money or they be dependent on pocket money from their [parents this would not matter much because my magazine will be produced monthly. I don't think the race of the reader would affect my magazine because is race-free.
