Sociology is the scientific study of human social behavior and society. It examines how social structures, institutions, and interactions shape individuals and their experiences, while also exploring how individuals influence society. This field investigates social patterns, inequality, culture, and the interplay between individual agency and social forces. Key sociological concepts include social structure, interaction, culture, socialization, and stratification. Founding figures like Comte, Durkheim, Weber, Marx, and Du Bois developed influential theories and methods. Research approaches range from quantitative surveys to qualitative ethnographies, all aimed at understanding social phenomena.
