Which of the following is considered a characteristic used for defining demographics?

Family size is a characteristic commonly used for defining demographics because it directly relates to the composition and structure of a household. Demographics typically include measurable statistics that describe a population’s characteristics, such as age, gender, income, marital status, and family size. This information is crucial for organizations and researchers when analyzing populations or planning services and products to meet the needs of specific groups.

In terms of relevance to demographic studies, family size can indicate market potential, social dynamics, and economic needs within a community. For example, larger families may require different housing options, educational resources, or products tailored for children, while smaller families may have different priorities.

The other options, such as favorite sports teams, artistic preferences, and travel habits, tend to reflect personal interests or behaviors and are less standardized or quantifiable than demographic characteristics. While these factors can be relevant to market research or sociocultural studies, they do not specifically categorize populations in the same way that demographic data like family size does.
