Which are the three components of socioeconomic status (SES)?

• A. Income, Education, Occupation/Social Status
• B. Income, Education, Housing Type
• C. Education, Neighborhood, Occupation
• D. Income, Education, Access to Food

Answer: (A)

Socioeconomic status is understood as a combination of resources and position in society that influence health-related opportunities and risks. The three core components are income, education, and occupation (or social status).

Income reflects the material resources a person can access, which affects living conditions, healthcare, and the ability to cover essentials. Education represents knowledge and cognitive resources that influence health literacy, employment prospects, and the ability to navigate systems. Occupation or social status captures the prestige, social roles, and work-related exposures or benefits (like sick leave or health insurance) that come with certain jobs.

These three domains together provide a consistent framework used in epidemiology to quantify SES and study its impact on health. Other options include housing type, neighborhood, or access to food. While these are related to SES and can reflect underlying resources, they are not the standard triad that defines SES on its own.
