Arunachal Pradesh can be roughly divided into a set of semi-distinct cultural spheres, on the basis of tribal identity, language, religion and material culture: the Tibetic-speaking Monpa area bordering Bhutan in the west, the Tani area in the centre of the state, the Mishmi area to the east of the Tani area, the Tai/Singpho/Tangsa area bordering Myanmar, and the Naga area to the south, which also borders Myanmar.
In between there are transition zones, such as the Aka/Hruso/Miji/Sherdukpen area, between the Tibetan Buddhist tribes and the animist Tani hill tribes.
In addition, there are isolated peoples scattered throughout the state, such as the Sulung.

Within each of these cultural spheres, one finds populations of related tribes speaking related languages and sharing similar traditions.
In the Tibetic area, one finds large numbers of Monpa tribespeople, with several subtribes speaking closely related but mutually incomprehensible languages, and also large numbers of Tibetan refugees.
Within the Tani area, major tribes include the Nyishi.
Apatani also live among the Nyishi, but are distinct.
In the centre, one finds predominantly Galo people, with the major sub-groups of Karka, Lodu, Bogum, Lare and Pugo among others, extending to the Ramo and Pailibo areas (which are close in many ways to Galo).
In the east, one finds the Adi with many subtribes including Padam, Pasi, Minyong and Bokar, among others.
Milang, while also falling within the general Adi sphere, are in many ways quite distinct.
Moving east, the Idu, Miju and Digaru make up the Mishmi cultural-linguistic area.

Moving southeast, the Tai Khamti are linguistically distinct from their neighbours and culturally distinct from the majority of other Arunachalese tribes.
They follow the Theravada sect of Buddhism.
 They also exhibit considerable convergence with the Singpho and Tangsa Naga tribes of the same area, all of which are also found in Burma.
The Khamptis and Singphos have a huge demographic presence even in the neighbouring state of Assam, in places viz.
Naharkatiya, Narayanpur of Lakhimpur districts of Assam.
They one of the most recent people group migrated to Arunachal region from Burma and Assam.
The Nocte Naga and Wancho Naga are another two major ethnic tribes.
Both the tribes exhibit very much cultural similarities.
Finally the Deori tribe is also a major community in the state, with their own distinctive identity.
They are the descendants of the priestly class of Chutia people who were allowed to continue their livelihood after the defeat of the Chutias.
Deoris are one of the only Arunachal tribe in the historical records-which shows they are among the first ethnic groups to inhabit the Himalayas of the districts of Dibang Valley and Lohit, before the arrival of other many tribes in the region between 1600 and 1900.

Literacy has risen in official figures to 66.95% in 2011 from 54.74% in 2001.
The literate population is said to number 789,943.
The number of literate males is 454,532 (73.69%) and the number of literate females is 335,411 (59.57%).
