Companies also track demographics like education, household size and occupation. Most demographics are defined or delineated by specific ranges. For example, the age demographic may divided into ranges such as 18 to 24; 25 to 34; 35 to 54; and 55 years and over. People within these age groups have different values. Their preferences for certain products or services may vary as well.
A demographic is a subset of a population that shares a common factor such as age, income or education level. The Millennial generation, for example, is the demographic cohort that immediately follows Generation X. Although there is a great deal of variation from one individual to another within any generational cohort, the particular environment for any generation affects those individuals in ways that are observable as broad tendencies.
