Demographics

Demographics basically tell a marketer who might be interested in buying a product. 

The success of any business relies on understanding the demographics of the target customers you wish to sell the product to. The information known will affect pricing, packaging, promotion and place. Any provider needs to understand demographics in order to decide exactly what product will include. The first step in reaching a customer is understanding who they are and about them. Having information about a person's age, gender, income and education, tells a marketer how likely a person is to make a purchase or require a service. In the day and age we are currently in it is much more cost effective and efficient to be able to target one's message to the people with the greatest propensity to make a purchase, rather than just attempting to advertise to the entire world. Having a full insight into the target audience gives the business selling the product a high advantage to be able to sell the product better. This is why understanding demographics is so important.
