In 2013, the Peoples Linguistic Survey of India (PLSI) report - TopicsExpress

In 2013, the Peoples Linguistic Survey of India (PLSI) report showed that there are 780 languages spoken in the country. In contrast, the 2001 census listed just 122 languages. While the census does not count languages spoken by less than 10000 people, the PLSI takes every lang into account...however few d numbers who speak it... More than 400 of these languages r spoken by tribals and nomads.While Hindi has around 40 crore speakers, Majhi, a local dialect, spoken by people living near West Bengal-Sikkim border has only 4 speakers... Imagine somebody trying 2 learn all of them... Nobody can beat India in diversity...
