Sociology is the study of human social relationships and institutions. Sociology's subject matter is diverse, ranging from education to religion, from the family to the state, from the divisions of gender and social class to the shared beliefs of a common culture, and from social stability to radical societal change. What unifies these diverse topics of study, however, is sociology's core purpose of understanding how human action and consciousness both shape and are shaped by surrounding cultural and social structures.Sociology is an exciting and enlightening field of study that analyzes and explains important issues in our personal lives, our communities, and the world. At the individual level, sociology investigates the social causes and consequences of things such as emotions and ideologies, racial identity, sexuality, health and wellness, and crime. At the societal level, sociology addresses issues such as poverty and wealth, prejudice and discrimination, schools and education, law and the criminal justice system, and social movements. And at the global level, sociology studies such phenomena as political power, migration, war, terrorism, human rights and economic development. Students of sociology are challenged to look beyond the normal, taken-for-granted views to develop deeper and revealing understandings of the world around us.
