Demographics are primarily concerned with which of the following factors?

Demographics specifically focus on the statistical characteristics of a population and are primarily concerned with measurable factors such as gender, income, age, race, and education level. These characteristics are essential in public relations as they help practitioners understand their target audience and tailor their communications effectively.

For example, knowing the income level of a target group can influence the pricing strategy for products or services, while understanding age demographics can impact the messaging and platforms used for outreach. This quantitative data plays a crucial role in developing strategies and campaigns that resonate with specific segments of the population, making it easier to align public relations efforts with audience needs and preferences.

In contrast, the other options relate to different fields of study or characteristics that are not primarily demographic. Psychological characteristics, political affiliations, and behavioral changes pertain more to psychographics and sociocultural factors, which involve qualitative aspects of consumer behavior rather than the statistical data that demographics describe.
