Demographics

Demographics are pieces of statistical data relating to the population and particular groups within it. The data can be to do with their gender, age, race, level of education, income level, and level of employment. Within media demographics are useful when researching who the audience for a film will be. 

NRS social grades define populations and therefore media companies would look at these to see the audience they were aiming for.
