Tanzania Population and Language

Ethnic diversity is high in Tanzania, which houses around 120 different peoples. On the mainland, bantu people dominate, of which sukuma is the largest group. On the islands of Zanzibar and Pemba there are both Bantu people and residents of Arab descent. The country has very high birth rates and almost half the population is under 15 years.

Most of the residents of Zanzibar and Pemba are of African origin, but there is also a group of Arab roots. The Arabs have traditionally depended on trade and were formerly Zanzibar’s upper class. In the islands, there is also a minority of Indian and Pakistani descent.

Few ethnic conflicts

No nation has dominated the others, and few groups have developed strong feelings of ethnic belonging. The country has therefore largely avoided the ethnic conflicts that have been so devastating for several neighboring countries, such as Rwanda. However, since the 1990s tensions between Christians and Muslims have increased (see Religion).

Tanzania has been receiving large numbers of refugees from neighboring countries since the 1970s. During the civil war in Rwanda and Burundi in the 1990s, almost one million people fled to Tanzania. Most of them returned to their homeland, but some became residents of Tanzania, which in 2014 had granted citizenship to around 200,000 Burundians (see Foreign Policy and Defense).

When fighting broke out again in Burundi in 2015, a new wave of refugees came to Tanzania. In March 2019, there were nearly 200,000 Burundian refugees in Tanzania, according to the UN agency UNHCR. At the same time, more than 84,000 refugees from the Congo-Kinshasa stayed in the country since new fighting erupted in their home country.

The population is unevenly distributed across the country. Smaller areas – mainly around Mount Kilimanjaro, along Lake Malawi and south of Lake Victoria – are densely populated. On the inner high plateau, however, few people live. In search of work, many Tanzanians have moved to the coast and the larger cities. But even though townships have quickly grown up around Dar es Salaam, Tanzania is still one of the least urbanized countries in Africa.


The country’s official language is Swahili (or Kiswahili). In practice, English also functions as an official language, used in higher education, the judiciary, commerce and government.

Swahili is a bantu language, which was initially spoken in coastal areas of Tanzania and Kenya. It is the native language of about 15 million people and is spoken as a second language by over 100 million people in eastern Africa. Throughout history, Swahili has been used as a trading language and has been influenced by, among others, Arabic, English, Hindi and Portuguese.

In Tanzania, more than 100 local languages ​​and dialects are also spoken. On the coast and on Zanzibar and Pemba, many speak Arabic.
