Rolling Stone magazine - Target audience

Rolling Stone
Audience of 11,899 in which 60% are male and 40% are female
They target an age of 18+, and 27% of the readers are between 18-24. Another 27% are aged from 25-34, 20% from 35-44, 14% from 45-54 and a small 13% from the age of 55 and above.

This is similar to my magazine, however I plan to make mine 50% male and 50% female. I chose this as alot of the indie genre magazines are more male than female. My age range is also slightly differrent, as I want to start mine from 16 rather than 18.
