Question 13

Age is a demographic variable.

Demographic variables are characteristics of a population and are often used in statistical analysis. Age is a fundamental demographic variable as it categorizes individuals based on their years, influencing various aspects such as behavior, preferences, and needs.

A) Lifestyle

Lifestyle refers to the way in which a person lives, encompassing habits, activities, and interests. While it can influence consumer behavior, it is not considered a demographic variable as it does not represent a static characteristic of a population.

B) Personality

Personality pertains to the individual traits and characteristics that define how a person thinks, feels, and behaves. Like lifestyle, personality is a psychological construct rather than a demographic variable, which focuses on quantifiable traits.

C) Age

Age is a classic example of a demographic variable. It can be measured and categorized, providing essential data for understanding population dynamics, market segmentation, and social trends.

D) Usage rate

Usage rate measures how frequently a product or service is used by individuals or groups. Although it provides valuable insights into consumer behavior, it is not a demographic variable because it relates to behavior rather than a characteristic of a population.

Conclusion

Age is the only option that qualifies as a demographic variable, as it provides essential quantifiable data about a population. The other options, while relevant in various contexts, do not reflect the static characteristics typically associated with demographic analysis. Understanding demographic variables like age is crucial for effective marketing, social research, and policy-making.
