Which demographic parameter includes income and social class?

The correct answer is socioeconomic status, as this parameter specifically encompasses both income level and social class within its definition. Socioeconomic status (SES) is used to describe individuals or groups based on their economic and social position relative to others, which generally includes income, education level, and occupational prestige. It is a critical factor in understanding various health outcomes and social determinants of health.

In contrast, race refers to categories based on physical characteristics, such as skin color and facial features, which do not inherently include socioeconomic factors. Ethnicity pertains to cultural factors, including nationality, ancestry, and language, which also do not directly define social class or income. Relocation status is concerned with an individual's movement from one location to another and does not provide information regarding their economic or social background. Therefore, socioeconomic status is the most fitting term that integrates both income and social class as its core components.
