The word "demographic" refers to statistical data relating to the population and particular groups within it. It often encompasses factors such as age, race, gender, income level, and other characteristics that help define and analyze different segments of a population.
The term "demographic" originates from the Greek word "demos," meaning "people" or "population," combined with "graphy," which means "to write" or "to describe." Thus, it literally means "to write about people."
