The term __________ is often used to refer to differences in income levels, but it also includes variables beyond financial resources.

A) socioeconomic status
B) class
C) psychological stratification
D) sociological level

Socioeconomic status (SES) considers not only income, but also education level, occupation, and social status. These additional variables provide a more comprehensive understanding of a person's or group's economic and societal standing. Choice B (class) is also sometimes used to refer to differences in income, but it is generally less inclusive than the broader concept of SES. Choices C (psychological stratification) and D (sociological level) are not commonly used terms in discussions of socioeconomic status.
