Population Description: The Tsonga population is made of three sub-groups: the Ronga, Tswa and Tsonga (Shangaan). These avid fishermen all originated from the same indigenous Bantu-speaking peoples who traveled from the north (due to Shaka, the Zulu conqueror) to inhabit much of what is now called southern Mozambique, portions of the Republic of South Africa, and eastern and southern Zimbabwe. They speak Tsonga, a Niger-Congo language.

Population estimates for the Tsonga (Vatsonga) people are very difficult to interpret. This is partially due to the fact that name "Shangaan," a subgroup of the Tsonga, often refers to the entire group in written literature. This is incorrect, however an understandable error when one realizes that the term Tsonga is also a subset of the larger Tsonga group and simply another name for Shangaan. Therefore, it is very difficult to determine whether references are being made towards the larger Tsonga population or the Shangaan people specifically. The Tsonga are distinguished for their practice in face scarring. This was originally done to deter Arab slave traders, however it is now considered a sign of beauty. They are also known for their extensive and dramatic puberty rites.
