Research and Planning: My Target Audience

It is important to take into consideration the target audience when creating my music magazine, as I want the right people to buy it.
For my magazine the target audience will be:
Age: 15 - 21
Gender: Male and Female
Occupation: Student
Class: Working/Middle class
Wealth: Students stereotypically don't have much money, although the lower end of the age bracket may get money from their parents, and the higher end of the age bracket may have a part time job.
Interests: My target audience would have a large interest in Indie music, to the extent they would buy a magazine about it. They may also enjoy going to gigs at underground venues, such as student union academies.
Outlook for future: The people reading my magazine are likely to carry on into education as far as possible and get degrees. Large amounts of them may also play musical instruments such as guitars and drums, and may be in a band that they wish to continue with, getting gigs and a fan base.

The socio-economic grouping for my target audience is E.
