Which of the following best describes demographic data?

Demographic data represents quantitative information about a population's characteristics, such as age, gender, income level, education, and marital status. This type of data is essential for businesses and organizations as it allows them to understand the characteristics and structure of their target market. By analyzing demographic data, companies can tailor their marketing strategies, product offerings, and services to meet the specific needs and preferences of different segments of the population.

In contrast, the other options focus on different types of information. Qualitative information about customer preferences, like that mentioned in the first option, relates to subjective data that captures opinions or feelings rather than measurable characteristics. The third option highlights behavioral information regarding purchasing habits, which would include data on how often and why customers make purchases, rather than the demographic profiles of those customers. Lastly, psychographic details focus on consumers' lifestyles and values, which provide insights into attitudes and motivations rather than numeric population metrics. Thus, the selection of quantitative data emphasizes the statistical aspect of demographic information, making it the most accurate description.
