The north-central provinces of Zambezia and Nampula are the most populous, with about 45% of the population. The estimated four million Macua are the dominant group in the northern part of the country; the Sena and Shona (mostly Ndau) are prominent in the Zambezi valley, and the Tsonga and Shangaan people dominate in southern Mozambique. Other groups include Makonde, Yao, Swahili, Tonga, Chopi, and Nguni (including Zulu). Bantu people comprise 97.8% of the population, with the rest made up of Portuguese ancestry, Euro-Africans (''mestiço'' people of mixed Bantu and Portuguese ancestry), and Indians. Roughly 45,000 people of Indian descent reside in Mozambique.
