South Asian ethnic groups

The ethno-linguistic composition of the population of South Asia, that is the nations of India, Pakistan, Bangladesh, Nepal, Bhutan, Maldives and Sri Lanka is highly diverse. The majority of the population fall within two large linguistic groups, Indo-Aryan and Dravidian. Indian society is traditionally divided into castes or clans, not ethnicities, and these categories have had no official status since independence in 1947, except for the scheduled castes and tribes which remain registered for the purpose of affirmative action. In today's India, the population is categorized in terms of the 1,652 mother tongues spoken.
