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.
