Population of Tanzania

Tanzania is one of the most rapidly expanding nations in East Africa, with an estimated 2026 population of approximately 72.6 million people. Current estimates indicate the country holds the 22nd position globally and ranks as the 5th most populous nation in Africa. Most of the population resides in rural areas, though the country maintains a high annual growth rate of 2.87%, driven by significant natural increase and improving survival rates.

The population history of Tanzania is marked by steady expansion following the union of Tanganyika and Zanzibar in 1964. From a population of approximately 10 million in the early 1960s, the nation has grown nearly sevenfold due to consistently high birth rates and a relatively stable political environment compared to several neighboring states. This stability has allowed for uninterrupted demographic development and a sustained natural increase over several decades. Internal migration patterns were historically influenced by the Ujamaa village program, which sought to centralize rural populations for better service delivery. In recent years, economic shifts have redirected these movements toward major urban centers. Dar es Salaam has emerged as a primary destination for internal migrants, while the capital, Dodoma, has seen increased growth since the government formalized the transfer of administrative functions. Public health improvements have successfully lowered mortality rates, further contributing to the total population surge.

The country is characterized by a high annual growth rate of 2.87%, a figure driven largely by a fertility rate of 4.54 children per woman. This fertility level is the 12th highest in the world, ensuring that the population remains exceptionally youthful. Recent data shows a crude birth rate of 34.8 births per 1,000 people, which significantly outweighs the crude death rate of 5.7 per 1,000, resulting in a daily net addition of approximately 5,399 people. Projections indicate that if current trends continue, the total population will remain on a steep upward trajectory throughout the coming decades. While life expectancy has reached 67.2 years, indicating improved access to medical care and better nutritional outcomes, the high volume of births remains the primary driver of demographic change. The transition toward a larger urban population is expected to eventually influence fertility downward, but the current momentum ensures continued large-scale growth for the foreseeable future.

Tanzania has an estimated 2026 population density of 81.9 people per km² (212 per sq mi), reflecting high concentrations near coastal hubs and fertile inland lake zones.

Approximately 36.2% of the population resides in urban areas, a figure that is rising as cities like Dar es Salaam and Dodoma attract more residents from rural regions.

Tanzania holds a prominent demographic position, ranking 22 of 215 countries worldwide. Within the African continent, it is the 5th most populous nation, while in the Eastern Africa subregion, it ranks 2 of 16, trailing only Ethiopia. Its population density is higher than many of its neighbors, ranking 26th in Africa, supported by dense settlements along its 1,424 km (885 mi) coastline and around the productive Great Lakes regions. This density of 81.9 people per km² (212 per sq mi) contrasts with the more sparsely populated interiors of bordering countries like Zambia or the Democratic Republic of the Congo. Despite its large total population, Tanzania remains less urbanized than the global average, with an urbanization rank of 180 of 215 countries, indicating a unique demographic profile where rural agricultural communities still form the backbone of the nation.
