Language
The languages of India primarily belong to two major linguistic families, Indo-European (whose branch Indo-Aryan is spoken by about 70% of the population) and Dravidian (spoken by about 22%). Other languages spoken in India come mainly from the Austro-Asiatic and Tibeto-Burman linguistic families, as well as a few language isolates.

Individual mother tongues in India number several hundred, making it linguistically one of the most diverse countries in the world. The North East itself is considered to be one of the most linguistically diverse regions in Asia, and therefore the world. The most common languages in Assam are Assamese, Bengali and Bodo. The most commonly heard tongues in Meghalayaspeak Khasi, Garo, Assamese, English and Bengali. In Arunachal Pradesh dozens of tribal languages compete alongside Assamese and some Bengali. A high level of bilingualism exists in the region.
