Languages of India
Until the Twenty-first Amendment of the Constitution of India in 1967, the country recognised 14 official regional languages. The Eighth Schedule and the Seventy-First Amendment provided for the inclusion of Sindhi, Konkani, Meitei and Nepali, thereby increasing the number of official regional languages of India to 18. The Eighth Schedule of the Constitution of India, as of 1 December 2007, lists 22 languages, which are given in the table below together with the speaking population and the regions where they are used. 
The individual states, the borders of most of which are or were drawn on socio-linguistic lines, can legislate their own official languages, depending on their linguistic demographics. The official languages chosen reflect the predominant as well as politically significant languages spoken in that state. Certain states having a linguistically defined territory may have only the predominant language in that state as its official language, examples being Karnataka and Gujarat, which have Kannada and Gujarati as their sole official language respectively. Telangana, with a sizeable Urdu-speaking Muslim population, has two languages, Telugu and Urdu, as its official languages.
Languages of India
Article 343 of the Indian constitution stated that the official language of the Union should become Hindi in Devanagari script instead of the extant English. But this was thought to be a violation of the constitution's guarantee of federalism. Later, a constitutional amendment, , allowed for the continuation of English in the Indian government indefinitely until legislation decides to change it. The form of numerals to be used for the official purposes of the Union were supposed to be the international form of Indian numerals, distinct from the numerals used in most English-speaking countries. Despite the misconceptions, Hindi is not the national language of India. The Constitution of India does not give any language the status of national language.
