The document summarizes different sociological perspectives on family roles and the division of domestic labor within households. It discusses Parsons' view of instrumental and expressive roles separated by gender. While early studies found more segregated roles, more recent research shows trends toward more symmetrical families with shared domestic duties between men and women. However, other studies have found limited progress toward equality. Decision-making and control of finances within families is also discussed, with men often retaining more power even when wives contribute financially. Explanations for the persistence of traditional gender roles include cultural norms of patriarchy as well as economic factors.
