Ideas and Planning. - Who is The Audience?

My magazine will be aimed at Both Female and Male students, aged 16-19. I decided to base my cover on this specific audience because I am planning to use 'general' cover lines and topics that relate to both sexes. Also, i think it is more suitable for the institution of the magazine to aim the product at all students as i decided the meaning of the college magazine is to Inform students of events and news happening in the college during the week of the issue, and therefore this would be the most practical audience for the magazine.
