Reaserch into a potential target audience

I've been researching into a potential target audience for my music magazine so I decided to use social media as it is a great way to get information quickly from the public. Twitter has recently introduced polls so I thought I would take advantage of this and create a poll to find out what age range is most likely to listen to alternative-pop music the most, as this is genre the artists that feature in my music magazine. From the results above it is clear that 16-19 is the age the public thought would listen to this type of music and this is helpful for me as I too thought that 16-19 is the most suitable age range, however 22% thought 12-15 is the age range likely to listen to alternative-pop music which I do have to take into consideration as a younger audience may like my music magazine too. Doing this has helped with my target audience choice as knowing my demographic before hand will help me create a better magazine.
