India
India is home to two major language families: Indo-Aryan (spoken by about 74% of the population) and Dravidian (spoken by 24% of the population). Other languages spoken in India come from the Austroasiatic and Sino-Tibetan language families. India has no national language. Hindi, with the largest number of speakers, is the official language of the government. English is used extensively in business and administration and has the status of a "subsidiary official language"; it is important in education, especially as a medium of higher education. Each state and union territory has one or more official languages, and the constitution recognises in particular 22 "scheduled languages".
Eighth Schedule to the Constitution of India
The Eighth Schedule to the Constitution of India lists the official languages of the Republic of India. At the time when the Constitution was enacted, inclusion in this list meant that the language was entitled to representation on the Official Languages Commission, and that the language would be one of the bases that would be drawn upon to enrich Hindi, the official language of the Union. The list has since, however, acquired further significance. The Government of India is now under an obligation to take measures for the development of these languages, such that "they grow rapidly in richness and become effective means of communicating modern knowledge". In addition, a candidate appearing in an examination conducted for public service is entitled to use any of these languages as the medium in which he or she answers the paper.
