Eight of Fiji's fourteen Provinces are in Viti Levu.  The Provinces of Ba, Nadroga-Navosa, and Ra comprise the Western Division, while Naitasiri, Namosi, Rewa, Serua, and Tailevu form the Central Division.  In part because of its high concentration of Indo-Fijians, whose ancestors came mostly as indentured workers from India between 1879 and 1916, the political dynamics of western Viti Levu are somewhat different from those of eastern Viti Levu, where, apart from the multi-racial urban areas, indigenous Fijians are more heavily concentrated.
