About:

• Opposition parties esp. in NorthEast have criticised this as “Hindi imposition”.
  
  
• The 2011 linguistic census accounts for 121 mother tongues, including 22 languages listed in the 8th Schedule of the Constitution. Hindi is the most widely spoken, with 52.8 crore individuals, or 43.6% of the population, declaring it as their mother tongue.
  
  
• The next highest is Bengali, mother tongue for 97 lakh (8%) — less than one-fifth of Hindi’s count.
  
  
• In terms of the number of people who know Hindi, the count crosses more than half the country. Nearly 13.9 crore (over 11%) reported Hindi as their second language, which makes it either the mother tongue or second language for nearly 55% of the population.
  
  
• Hindi has been India’s predominant mother tongue over the decades, its share in the population rising in every succeeding census. In 1971, 37% Indians had reported Hindi as their mother tongue, a share that has grown over the next four censuses to 38.7%, 39.2%, 41% and 43.6% at last count.
  
  

What explains Hindi’s high numbers?

• One obvious explanation is that Hindi is the predominant language in some of India’s most populous states, including Uttar Pradesh, Madhya Pradesh and Bihar.
  
  
• Another reason is that a number of languages are bracketed under Hindi by census enumerators. Among them is Bhojpuri, and 5 crore people have reported Bhojpuri as their mother tongue, but the census has decided that Bhojpuri is Hindi.
