Arakanais
Apart from the Bengali majority, there are a number of small communities of ethnic minorities in the area. Many of the resident Rakhine people are believed to have settled here during the Arakanese rule of Chittagong (1459–1666), though the event is not historically traceable. The Rakhine population in Khagrachari District migrated from the surrounding area and built up their permanent abode at Ramgarh in the 19th century. Other ethnic groups include the recently migrated Tripuri people. In the District of Chittagong that includes Sitakunda, the population ratio by religion in 2001 was Muslim 83.92%, Hindu 13.76%, Buddhist 2.01% and Christian 0.12%, with 0.19% following other religions. In 1981, it was Muslim 82.79%, Hindu 14.6%, Buddhist 2.23% and Christian 0.21%, with 0.19% following other religions. Chittagonian, a derivative of Bengali spoken by 14 million people mainly in the Chittagong district, is the dominant language.
