This document defines key concepts related to social structure including status, position, and roles. It differentiates between ascribed status (received at birth with no control), achieved status (earned through personal efforts), and master status (dominates and is known by the community). Position indicates a particular place in a social system, while roles represent the expected behaviors, rights, and obligations associated with a specific position. Role conflict occurs when one has more than one status, role sets refer to the number of roles with one status, and role strain results when one status implies many roles and expectations.
