Which is a common characteristic of demographics?

Demographics primarily involve statistical data that describe specific characteristics of a population. Commonly, these include measurable and observable attributes such as age, education levels, gender, income, marital status, and ethnic background. Choice C highlights two fundamental demographic characteristics: age and education levels.

Understanding a target audience's age can influence marketing strategies, as different age groups often have varying preferences and consumption habits. Similarly, education levels can affect purchasing power and consumer behavior, making it crucial for advertisers to tailor their messages effectively.

When marketers analyze demographics, they utilize this data to better predict consumer behaviors and create targeted advertising strategies that resonate with specific segments of the population. Thus, the accurate identification of age and education levels as demographics underscores their importance in understanding and responding to market needs.
