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".
Languages with official status in India
The Indian constitution draws a distinction between the language to be used in Parliamentary proceedings, and the language in which laws are to be made. Parliamentary business, according to the Constitution, may be conducted in either Hindi or English. The use of English in parliamentary proceedings was to be phased out at the end of fifteen years unless Parliament chose to extend its use, which Parliament did through the Official Languages Act, 1963. In addition, the constitution permits a person who is unable to express themselves in either Hindi or English to, with the permission of the Speaker of the relevant House, address the House in their mother tongue.
