Demographics mean population description
Demography comes from the Greek words demos (people) and Graphoo (describe). Demography is thus describing the population. With demography you are talking about the study of the population, or a population group: not only the statistical data as the number of births and gender, but also the composition of interests and characteristics. For the creation of (AD) campaigns, one also often assumes a certain demographics: for example, only women between the age of 20 and 40 want to speak with Tattoes.
