Scheduled Castes and Scheduled Tribes
The Scheduled Castes (SCs) and Scheduled Tribes (STs) are official designations given to various groups of historically disadvantaged people in India. The terms are recognised in the Constitution of India and the various groups are designated in one or other of the categories. During the period of British rule in the Indian subcontinent, they were known as the Depressed Classes.
In modern literature, the Scheduled Castes are sometimes referred to as Dalits.Scheduled Tribes is used as an official term for Adivasis.
The Scheduled Castes and Scheduled Tribes comprise about 16.6 percent and 8.6 percent, respectively, of India's population (according to the 2011 census). The Constitution (Scheduled Castes) Order, 1950 lists 1,108 castes across 29 states in its First Schedule, and the Constitution (Scheduled Tribes) Order, 1950 lists 744 tribes across 22 states in its First Schedule.
Since independence, the Scheduled Castes and Scheduled Tribes were given Reservation status, guaranteeing political representation. The Constitution lays down the general principles of affirmative action for SCs and STs.
