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.

India is a multilingual country with 1,635 languages (including dialects and sub dialects) while Indian currency notes display 15 major languages. Although smartphone penetration is increasing in India, text input in Indic scripts has been a challenge for many years. According to the 2005 India Human Development Survey, the surveyed households reported that 72 per cent of men did not speak any English, 28 per cent spoke some English, and five per cent spoke fluent English. Among women, the corresponding percentages were 83, 17, and 3. While Indian languages are preferred in other means of communication in India (e.g. oral and written communication, radio, TV, newspapers and magazines), English is still the most preferred language for text input.
