家庭妇女 refers to a woman whose primary role is managing the household and caring for the family — essentially a 'housewife' or 'homemaker'. The term is neutral in tone but can carry slightly old-fashioned or traditional connotations in modern urban contexts, where 全职太太 (full-time wife) is sometimes preferred. It's a noun phrase that functions as a single unit, often used in discussions about gender roles, family structure, or social status.
