The Khoisan languages are a number of African languages once classified together, originally by Joseph Greenberg. Khoisan is defined as those languages that have click consonants and do not belong to other African language families. For much of the 20th century, they were thought to be genealogically related to each other, but this is no longer accepted. They are now held to comprise three distinct language families and two language isolates.
Demographic features of the population of Tanzania include population density, ethnicity, education level, health of the populace, economic status, religious affiliations, and other aspects of the population.
The number of languages natively spoken in Africa is variously estimated at between 1,250 and 2,100, and by some counts at over 3,000. Nigeria alone has over 500 languages, one of the greatest concentrations of linguistic diversity in the world. The languages of Africa belong to many distinct language families, among which the largest are:
Hadza is a language isolate spoken along the shores of Lake Eyasi in Tanzania by around 1,000 Hadza people, who include in their number the last full-time hunter-gatherers in Africa. It is one of only three languages in East Africa with click consonants. Despite the small number of speakers, language use is vigorous, with most children learning it, but UNESCO categorizes the language as vulnerable.
Oropom is an African language, possibly spurious and, if real, almost certainly extinct. The language was purportedly once spoken by the Oropom people in northeastern Uganda and northwestern Kenya between the Turkwel River, the Chemorongit Mountains, and Mount Elgon.
Dahalo is an endangered Cushitic language spoken by around 500–600 Dahalo people on the coast of Kenya, near the mouth of the Tana River. Dahalo is unusual among the world's languages in using all four airstream mechanisms found in human language: clicks, implosives, ejectives, and pulmonic consonants.
In Uganda the most spoken language in the capital city is Luganda, followed by English, as all schools in Uganda use it in their studies due to the introduction of English during the colonial period. English is also the language of business and judicial matters. Most spoken after Luganda and English is Swahili. This language is more common in neighbouring Kenya and Tanzania. Swahili is taught in schools as an optional additional language and it is mostly spoken by the Ugandan army. In 2005, there were talks to include Swahili as the second official language as it was seen as neutral, however this is still not ratified by the government. Swahili is used among some communities bordering South Sudan and Kenya.
The Rendille are a Cushitic ethnic group inhabiting the Eastern Province of Kenya.
Kenya is a multilingual country.
The main languages spoken in Eritrea are Tigrinya, Tigre, Kunama, Bilen, Nara, Saho, Afar, and Beja. The country's working languages are Tigrinya, Arabic, English.
The population of Africa has grown rapidly over the past century and consequently shows a large youth bulge, further reinforced by a low life expectancy of below 50 years in some African countries. Total population as of 2020 is estimated to be more than 1.3 billion, with a growth rate of more than 2.5% p.a. The total fertility rate for Africa is 4.7 as of 2018, the highest in the world according to the World Bank. The most populous African country is Nigeria with over 206 million inhabitants as of 2020 and a growth rate of 2.6% p.a.
The Sandawe are an indigenous ethnic group of Southeast Africa, based in the Chemba District kwamtoro ward of Dodoma Region in central Tanzania. In 2000, the Sandawe population was estimated to be 40,000.
The Iraqw People are a Cushitic ethnic group inhabiting the northern Tanzanian regions. They are believed to have originated from the southwestern Arusha and Manyara regions of Tanzania, near the Rift Valley. The Iraqw people then settled in the southeast of Ngorongoro Crater in northern Karatu District, Arusha Region, where the majority of them still reside. In the Manyara region, the Iraqw are a major ethnic group, specifically in Mbulu District, Babati District and Hanang District.
The Hadza, or Hadzabe, are a protected hunter-gatherer Tanzanian indigenous ethnic group from Baray ward in southwest Karatu District of the Arusha Region. They live around the Lake Eyasi basin in the central Rift Valley and in the neighboring Serengeti Plateau. As of 2015, there are between 1,200 and 1,300 Hadza people living in Tanzania. However, only around 400 Hadza still survive exclusively based on the traditional means of foraging. Additionally, the increasing impact of tourism and encroaching pastoralists pose serious threats to the continuation of their traditional way of life.
The Alagwa are a Cushitic ethnic group mostly based in the Kondoa District of the Dodoma Region in central Tanzania, an area well known for rock art. Smaller numbers of Alagwa reside in the Hanang district of the Manyara Region in Tanzania, as well. They speak the Alagwa language as a mother tongue, which belongs to the South Cushitic branch of the Afro-Asiatic family. In 2022, the Alagwa population was estimated to number 52,816 individuals, and Mous (2016) estimates the number of speakers to be slightly over 10,000.
Kwʼadza (Qwadza), or Ngomvia, is an extinct Afroasiatic language formerly spoken in Tanzania in the Mbulu District. The last speaker died sometime between 1976 and 1999.
The Bantu peoples are an ethnolinguistic grouping of approximately 400 distinct native African ethnic groups who speak Bantu languages. The languages are native to 24 countries spread over a vast area from Central Africa to Southeast Africa and into Southern Africa.
