Which of the following factors primarily determines social class?

The primary determinant of social class is income, education, and occupation. These three factors are crucial because they reflect an individual's economic position and access to resources within society. Income provides a measure of financial stability and purchasing power, which influences the quality of life and opportunities available to a person. Education levels often correlate with better job prospects and higher income potential, making it a key indicator of social class. Occupation plays a significant role as well, as different jobs come with varying levels of prestige, authority, and economic rewards. Together, these elements help to categorize individuals into different social classes, shaping their experiences and interactions within society.

While friendship circles, media consumption, and family size can influence one's social context, they are not the foundational elements that establish social class. Friendship circles may reflect social connections or networks but do not affect an individual's economic status directly. Media consumption can indicate cultural interests or trends within a class, but it does not serve as a primary determinant of class itself. Family size may indicate personal circumstances, but it is not a direct measure of economic or social standing. Thus, income, education, and occupation serve as the core factors driving social class differentiation.
