Languages with official status in India
The Constitution of India designates the official language of the Government of India as Hindi written in the Devanagari script, as well as English. There is no national language as declared by the Constitution of India. Hindi is used for official purposes such as parliamentary proceedings, judiciary, communications between the Central Government and a State Government. States within India have the liberty and powers to specify their own official language(s) through legislation and therefore there are 22 officially recognized languages in India of which Hindi is the most used. The number of native Hindi speakers is about 25% of the total Indian population; however, including dialects of Hindi termed as Hindi languages, the total is around 44% of Indians, mostly accounted from the states falling under the Hindi belt. Other Indian languages are each spoken by around 10% or less of the population.
North India
Linguistically, North India is dominated by Indo-Aryan languages. It is in this region, or its proximity, that Sanskrit and the various Prakrits are thought to have evolved. The most widely spoken language in this region is Hindi. It has official status in the states of Haryana, Himachal Pradesh, Rajasthan, Uttarakhand and Uttar Pradesh as well as in the union territory of Delhi. Punjabi has predominance in the state of Punjab where it is the official language. It also has significant presence in the nearby regions. Urdu enjoys official status in Delhi, Jammu and Kashmir and Uttar Pradesh. Further north in Jammu and Kashmir, major languages are Dogri and Kashmiri. Languages like Bengali, Bhili and Nepali are also spoken in notable numbers throughout the region. A large part of North India is taken up by the so-called Hindi Belt, which here subsumes most of the Rajasthani languages, dialects of Western Hindi, Bhojpuri, Awadhi, Garhwali and Kumaoni.
