Definition of Caste. A caste is a social category to which a person belongs involuntarily (one's social status is ascribed); a caste contrasts with a social class. A caste system, then, is a social structure in which people belong to such social categories; historically, an example is the caste system of India.In sociology, a caste system describes one form of social stratification.astes also explain why some societies offer little social mobility: if a person occupies a low social status in that person's caste, then it is difficult or impossible for that person to achieve a higher status, as typically one cannot change one's caste.
A 1995 study notes that the caste system in India is a system of exploitation of poor low-ranking groups by more prosperous high-ranking groups. In India, 36.3% of people own no land at all, 60.6% own about 15% of the land, with a very wealthy 3.1% owning 15% of the land.he social stratification (in Tamilnadu) was established 4,000 to 6,000 years ago and there was little admixture during the last 3,000 years, implying a minimal genetic impact of the Varna (caste) system from the historically-documented Brahmin migrations into the area.
