According to Merriam-Webster, demographics are "the statistical characteristics of human populations (such as age or income) used especially to identify markets."
Demographics are used by political parties, businesses, marketing agencies, and companies in order to analyze trends and connections between population groups. The largest demographic survey in the United States is the Census, which occurs every ten years and collects demographic information about every citizen. Demographics can tell you what a person is like, in easy, digestible variables.
Examples of demographic information: age group, ethnicity, household income, number of children, and whether they are single/married/divorced.
