The Gogo (singular: mgogo, plural: Wagogo) are a Bantu ethnic and linguistic group based in the Dodoma Region of central Tanzania. In 1992 the Gogo population was estimated to number 1,300,000. The Gogo have historically been predominantly pastoralist and patrilineal (tracing descent and inheritance through the male line), but many contemporary Gogo now practice settled agriculture, have migrated to urban areas, or work on plantations throughout Tanzania.
