Bangladesh (previously East Pakistan between 1947 and 1971 and East Bengal before 1947) is largely ethnically homogeneous, and its name derives from the Bengali ethno-linguistic group which comprises 98% of the population. The Chittagong Hill Tracts, Sylhet, Mymensingh, Barisal and North Bengal regions are home to diverse indigenous peoples. There are many dialects of Bengali spoken throughout the region. The dialect spoken by those in Chittagong and Sylhet are particularly distinctive. About (90.4%) of Bangladeshis are Muslims, followed by Hindus (largest-minority) at (8.5%), Buddhists (0.6%) and Christians (0.4%) and others (0.1%) as per 2011 census.
