Demographics and social grading

Demographics are the measurable characteristics of media consumers such as age, gender, race, education and income level.

Social class grading table:

It's important that do things that are appropriate to your target audience. For example if it was targeted at grade A you could advertise instruments they could buy where as if it was grade E you would show competitions where they could win the instruments because they wouldn't have the money to buy them.
The group I will aim to create my magazine for will be mainly D. Young adults (students) who may not have jobs so wont be earning much money. This means I will have to keep the language very simple so it can be understood and I will have to include things that will attract to my target audience.
