Language Atlas of India, 2011

The Language Atlas of India 2011 is a cartographic attempt to record and publish data on languages and its distribution. It uses information recorded and published as a part of Census 2011. The first language atlas used data from the 1991 census and was published in 2004. Given that this project gives us a locational distribution of languages in India, the Atlas is a joint venture of the language division and the maps division. A ‘speaker’ of a language, in this Atlas, is someone who has returned the language as their mother tongue in Census 2011. The national rate of bilingualism in Census 2011 is at an all-time high – more than 26 per cent of the population. This Atlas has 74 maps with notes and has been divided into six sections: General (Chapter 1), Family-wise languages (Chapter 2), Scheduled Languages (Chapter 3), Non-Scheduled Languages (Chapter 4), Biligualism and trilingualism (Chapter 5) and Mother tongues and Scheduled Tribes (Chapter 6).
