India is the second most culturally, linguistically and genetically diverse geographical entity after the African continent.[50] India is home to two major linguistic families: Indo-Aryan (spoken by about 74% of the population) and Dravidian (spoken by about 24%). Other languages spoken in India come from the Austro-Asiatic and Tibeto-Burman linguistic families. Hindi, with the largest number of speakers,[97] is the official language of India.[98] English, which is extensively used in business and administration, has the status of a 'subsidiary official language.'[6] The constitution also recognises in particular 21 other languages that are either abundantly spoken or have classical status. The number of dialects in India is as high as 1,652.
