Dadra and Nagar Haveli has a sex ratio of 775 females for every 1,000 males, and a literacy rate of 77.65%. Tribal groups make up a large part of the population viz 62%. The most prominent are Dhodia (16.90%), Kokna (16.85%) and Warli (62.94%), with small groups of Koli, Kathodi, Naika, and Dubla scattered across the territory, collectively representing 3.31% of the population. Dhodias and Dubles mainly populate the Northern part, whereas Koknas and Warlis are found all over the Union Territory. They worship the primary deities of Dis (Sun) and Chand (Moon), and Narandev, Kanasari, Himai, Hirva, Veer, Rangtai and Vagdev. One prominent feature of this territory is that people from all over India form a part of non-tribal residents. DNH has many industries due to tax concessions granted to industry and therefore people from all over the country have migrated to the region. North Indians have a prime influence in the area. Gujarati is one of the three official languages, the others being Hindi and English. Besides Gujarati persons, one can find Marathi, Rajasthani, Bihari, Tamil, Uttar Pradeshi and people from several other states. The prime reason for such a diverse population is the industrial hub. Employment opportunities, good climate, and the landscape are highly appealing. Per the 2001 Census, out of the 137,225 ST persons of the UT, almost all were Hindus except for 3,796 Christians (2.8%). As a former Portuguese enclave, Silvassa has a significant Roman Catholic population. Kokna has the highest Christian population in 2001, 6.7%. Recently Digambara Jains constructed a temple in the capital city Silvassa. Swetambara Jains also have a temple in Dadra and Silvassa. There are 72 villages, mainly inhabited by the various tribal communities like the Warly (Warlie), Kokana, Dhodia, Koli, Kathodi, Naika, Dubla and Kolgha. The tribal communities are locally known as Adivasi (which means original inhabitant). Each community has its own culture, traditions and languages and dialects. None of these languages has written literature or script until today. The tribal communities consist of approximately 60% of the population of DNH.
