Customer survey questionnaires heavily depend on demographic questions. If your questionnaire results tell you that 65% of your respondents are Males in the 25 to 39 age group, your advertising would focus on that age and gender group as they would make up a large portion of your customer base. Your categories need to be broken up into divisions that make sense for your research.
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.
