Social stratification shapes societies by creating hierarchies based on wealth, status, and power. This unit explores how these systems form, persist, and impact individuals' lives. It covers key concepts, historical context, and theoretical frameworks for understanding social inequality. The unit also examines different types of stratification, from caste systems to modern class structures. It delves into social policies aimed at addressing inequality, methods for measuring stratification, and real-world case studies that illustrate these concepts in action.
