How is social change to be distinguished from other kinds of change?
Social change, unlike other forms of change, refers to significant changes that take place in the foundations of social structure and systems of a society. Other forms of change may impact certain aspects of social life without encompassing it as a whole. Such restrictions are not applied to social changes.
It does not include the small changes but only the big changes that alter the society fundamentally. The influence of such changes has to be both intensive and extensive.
Therefore, the changes that impact a large section of the society are called social changes. For example, a change in the government may not necessarily qualify as a social change. However a change in the social ideals from capitalism to socialism or abolition of practices like untouchability, that impact a large number of people, does represent social change.
