Target audience

The target audience that my group and I plan on aiming at is the younger generation, ages between about 15 upwards. Because we are focussing on the indie rock genre, we aim for our audience to be a part of the indie culture, and also a fan of indie/indie rock music.
Our target audience through the media:
Readers of Q, Rocksound and NME
Listeners of MTV, Q and 4Music.
Fans of Florence and the Machine, Arctic Monkeys, Lostprophets, etc.

On the other hand I understand that we are also aiming for anyone that is interested in indie music, or this particular genre and culture, of any age.

I collected some demographic data on the internet at www.itfacts.com about music buyers/listeners in the UK.
