Sociology is the study of society and social relationships. It examines how humans interact with each other and how their behaviors and ways of thinking can change over time due to different social factors. Sociology also analyzes communities, personal lives, and seeks to understand the reasons behind changes in how people live. It covers all aspects of human life and uses empirical methods to investigate relationships and institutions at both the social and personal levels. The scope of sociology is very broad, as it can be applied to understand and address problems within any society. It has no defined starting or ending points since it examines all factors influencing human life.
