Target Audience For My Magazine

I feel that the target audience for my new music magazine will be a niche audience. Also the magazine will interpolate the audience so that it will be specific to individuals and how the interpret the ideology of the magazine.
The demographics for the audience magazine will be both male and females around the 15-24 age range, I feel that the socio-economic group which my magazine will appeal to will be from around the C1-E category.
The psychographics for the audience which I have chosen for the magazine will also be people who are the majority of the time both inner and outer directed in life, I feel that this is a good audience because they will be both belongers and slightly society conscious.
Also I feel that on Maslow's hierarchy of needs they will be at the social stage because the people who read the magazine will want to belong to a part of a group.
