India
India is home to two major language families: Indo-Aryan (spoken by about 74% of the population) and Dravidian (spoken by 24% of the population). Other languages spoken in India come from the Austroasiatic and Sino-Tibetan language families. India has no national language. Hindi, with the largest number of speakers, is the official language of the government. English is used extensively in business and administration and has the status of a "subsidiary official language"; it is important in education, especially as a medium of higher education. Each state and union territory has one or more official languages, and the constitution recognises in particular 22 "scheduled languages".
Northeast India
According to 2011 Census of India, the largest cities in Northeast India are 
Northeast India constitutes a single linguistic region within the Indian national context, with about 220 languages in multiple language families (Indo-European, Trans-Himalayan/Sino-Tibetan, Kra–Dai, Austroasiatic, as well as some creole languages) that share a number of features that set them apart from most other areas of the Indian subcontinent (such as alveolar consonants rather than the more typical dental/retroflex distinction). Assamese, an Indo-Aryan language spoken mostly in the Brahmaputra Valley, developed as a "lingua franca" for many speech communities. Assamese-based pidgin/creoles have developed in Nagaland (Nagamese) and Arunachal (Nefamese), though their use has been on a decline in recent times. The Austro-Asiatic family is represented by the Khasi, Jaintia and War languages of Meghalaya. A small number of Tai–Kadai languages (Ahom, Tai Phake, Khamti, etc.) are also spoken. Trans-Himalayan/Sino-Tibetan is represented by a number of languages that differ significantly from each other, some of which are: Bodo, Rabha, Karbi, Mising, Tiwa, Deori, Biate etc. (Assam); Garo, Hajong, Biate (Meghalaya) Ao, Angami, Sema, Lotha, Konyak etc.(Nagaland); Mizo, Hmar, Chakma (Mizoram); Hrusso, Tanee, Nisi, Adi, Abor, Nocte, Apatani, Misimi etc. (Arunachal). Meitei is the official language in Manipur, the dominant language of the Imphal Valley; while "Naga" languages such as Poumai, Mao, Maram, Rongmei (Kabui) and Tangkul, and Kuki-Chin languages such as Thadou, Hmar, Simte and Paite predominate in individual hill areas of the state.
