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.
Modern language
Most children learn an official version of their native language or learn a local major lingua franca (for example Mandarin, Hindustani) in Asia-Pacific countries, and all subjects are taught in that lingua franca language except for foreign language lessons. Singapore, in which English is taught as a first language, is an exception. In India, Hindi and English is used for official communication and are both compulsory language to learn in many schools. Some students however also study other Indian languages. English is the most-studied foreign language in the People's Republic of China, India, Pakistan, Japan, South Korea, Republic of China (Taiwan), Singapore and Hong Kong. In China, English is a required language starting in third grade, although the quality of instruction varies greatly. In Nepal, almost all subjects are taught in English, except for Nepali literature.
