Which of the following factors is NOT included in demographics?

Demographics refer to statistical characteristics of a population, which typically include factors such as age, income, race, gender, and education level. These elements provide insights into the social and economic aspects of a group and are critical in market research and analysis.

Interest in travel, however, falls under psychographics rather than demographics. Psychographics encompass attitudes, interests, and lifestyle choices, which may influence travel behavior but do not define the demographic profile of individuals. Therefore, selecting interest in travel indicates an understanding that it pertains to personal preferences and behavioral attributes rather than the statistical identity represented by demographics.
