Languages with official status in India
The Constitution of India designates the official language of the Government of India as Hindi written in the Devanagari script, as well as English. There is no national language as declared by the Constitution of India. Hindi is used for official purposes such as parliamentary proceedings, judiciary, communications between the Central Government and a State Government. States within India have the liberty and powers to specify their own official language(s) through legislation and therefore there are 22 officially recognized languages in India of which Hindi is the most used. The number of native Hindi speakers is about 25% of the total Indian population; however, including dialects of Hindi termed as Hindi languages, the total is around 44% of Indians, mostly accounted from the states falling under the Hindi belt. Other Indian languages are each spoken by around 10% or less of the population.
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.
