Sociology is the study of group life: its characteristic changes, causes and consequences. It combines scientific and humanistic perspectives in the study of urban and rural life, family patterns and relationships, social change, inter-group relations, social class, environment, communications, health-seeking behavior, as well as social movements and community responses to disasters, natural and created.
