Sociology can be defined as the science that deals with human relationship. It is the study of how human beings relate with each other, how each individual relationship has been influenced by other people and the patterns which are formed out of their interactive relationships. Sociology emphasizes group relationships and total social environment. Sociology studies human behaviour in a different way from other academic approaches. Sociology looks at a wide range of behavior than economist or political scientist.
Political science studies the organization and functioning of system government. Sociology also study political life but less as an isolated phenomenon and more in terms of general sociological principles. The focus of the economist is on the production, distribution and consumption of goods and services. Sociology also study economic behavior but it relates closely to social and cultural factors such as age sex, social class and ethic groups. Where psychology study individual behaviour, sociologist study social behaviour.
Sociology deals with social behaviour that goes beyond the psychology on a single individual and necessarily focuses on the observation of categories or groups. With regards to social work it studies human behaviour on a micro scale, whereas sociology studies human behaviour on a macro scale. The focus of a social worker is behavioural change. Anthropology is another social science that is related to sociology. They both share an interest in the past, with history and are concern with contemporary events. As anthropology and sociology develops the distinction between them has become blurred.
However it has been argued that the difference between two disciplines is that anthropology emphasizes the study of a particular culture in its entirety and its uniqueness. Sociology on the other hand seeks to establish analytical principles of social organizations and social relationships and develop generalizations that are applicable to a wide variety of cultural context. Demography is the study of the population. All aspects of sociology are studied by demographers. Demography goes hand in hand with sociology, providing empirical data on which sociologist build theories.
