Swahili language
The exact number of Swahili speakers, be it native or second-language speakers, is unknown and a matter of debate. Various estimates have been put forward and they vary widely, from 50 million to over 100 million. Swahili serves as a national language of four nations: Tanzania, Kenya, Uganda, and the DRC. Shikomor, the official language in Comoros and also spoken in Mayotte (), is related to Swahili. Swahili is also one of the working languages of the African Union and officially recognised as a lingua franca of the East African Community. South Africa legalized the teaching of Swahili in South African schools as an optional subject beginning in 2020.
Swahili people
Although most Swahili live with living standards far below that of upper hierarchy of the wealthiest nations, the Swahili are generally considered a relatively economically powerful group due to their history of trade. They are comparatively well-off; According to the United Nations, Zanzibar has a 25% higher per capita GDP than the rest of Tanzania. This economic influence has led to the continued spread of their culture and language throughout East Africa.
