The national Census of India does not recognise racial or
ethnic groups within India,[120] but recognises many of the
tribal groups as Scheduled Castes and Tribes (see list of
Scheduled Tribes in India).
According to a 2009 study published by Reich et al., the
modern Indian population is composed of two genetically
divergent and heterogeneous populations which mixed in
ancient times (about 1,200–3,500 BP), known as Ancestral
North Indians (ANI) and Ancestral South Indians (ASI). ASI
corresponds to the Dravidian-speaking population of
southern India, whereas ANI corresponds to the Indo-Aryanspeaking population of northern India

Caste and community statistics as recorded from "Socially and
Educationally Backward Classes Commission" (SEBC) or Mandal
Commission of 1979. This was completed in 1983.
there has not yet been a proper consensus on contemporary
figures
The caste system divides Hindus into four main categories Brahmins, Kshatriyas, Vaishyas and the Shudras.
Many believe that the groups originated from Brahma, the Hindu
God of creation.
For centuries, caste has dictated almost every aspect of Hindu
religious and social life, with each group occupying a specific
place in this complex hierarchy.
