Gisbert:
“Social stratification is the division of society into permanent groups of categories linked with each other by the relationship of superiority and subordinations”.
Williams:
Social Stratification refers to “The ranking of individuals on a scale of superiority-inferiority-equality, according to some commonly accepted basis of valuation.
Melvin M Tumin:
“Social stratification refers to “arrangement of any social group or society into hierarchy of positions that are unequal with regard to power, property, social evaluation and psychic gratification”.
The three key principles of social stratification are as follows:
(i) Social stratification is not just a function for the individual difference but is a characteristic of a society
(ii) Social stratification is continuing from generation to generation
(iii) Social stratification is supported by a prototype of belief or ideology
