Linguistic rights
The constitution of India was first drafted on January 26, 1950. It is estimated that there are about 1500 languages in India. Article 343–345 declared that the official languages of India for communication with centre will be Hindi and English. There are 22 official languages identified by constitution. Article 345 states that "the Legislature of a state may by law adopt any one or more of the languages in use in the State or Hindi as the language or languages to be used for all or any of the official purposes of that State: Provided that, until the Legislature of the State otherwise provides by law, the English language shall continue to be used for those official purposes within the State for which it was being used immediately before the commencement of this Constitution".
People's Linguistic Survey of India
The Eighth Schedule of the Constitution of India recognizes 22 scheduled languages, excluding English, and the linguistic policies and funding of the Indian government are organised around this information. However, this information does not adequately convey the linguistic diversity of India. The 1961 Census of India had recorded 1652 languages being in use in India. However, it was decided to exclude languages spoken by less than 10,000 people in the 1971 Census, which brought down the figure to 108 languages. PLSI has followed the policy of including all languages in the survey, irrespective of the number of users. For example, it records a language called Chaimal in Tripura, which is spoken by only five people.
