Media theories on target audiences.

When looking at media theory's such as "GRASS" this will help me look deeper into my target audience:
"G" stands for gender and when looking at my magazine I feel it will appeal to both male and female, as everyone can listen to certain music and its not effected my gender.
"R" stands for race, i think any race can read my magazine as race cant possibly stop someone from liking a rock music magazine. I think if it came to religion atheists will me most interested as some rock music is not very religious and certain religious people may not approve of the music genre.
"A" stands for age and my magazine is aimed at people between the age of around thirteen to early twenty's but i think my magazine might still appeal to people that are slightly older such as adults in their thirty's.
The "SS" stands for "S"ocio-economic "S"tatus which is effected my wealth and jobs as if you are in the A group  you are known as the upper class who are business professionals, group B is the middle class who work in middle management, group C1 is lower middle class who work in trades and supervisory jobs, group C2 who are skilled middle class who are known as blue collar workers, group D which is the lower working class who are manual workers and finally group E which is subsidence who are pensioners and the unemployed. My magazine is looking at costing around one pound twenty and its going to be a weekly magazine, because of this i think my magazine can be aimed at all groups except the unemployed, as they wont get an income so they wont be able to afford it and it also wont sell to the pensioners unless they are still into rock music.
Another media theory is Psychographic profiling which consists of Mainstreamer's, Aspirer's, Succeeder's and Reformers, when looking at my magazine i think it will fit into the reformers group the most as they arn't interested in wealth and expensive things they just like to be normal and listen to music.
