About Tanzania
Tanzania is located in the eastern flank of the continent, including the Horn of Africa, the Great Rift Valley, and the islands of the western Indian Ocean. Its capital is Dodoma, and it covers roughly 945,087 square kilometres. The population of about 67.0 million makes it one of 14 countries that make up East Africa. Tanzania ranks among the East Africa region's top three by population, and ranks in the region's top three by reported GDP. The country marks its modern statehood from 1961.
East Africa contains some of the continent's fastest-growing economies and its highest concentration of major rift-valley landscapes, lakes, and protected wildlife areas. Swahili functions as a regional lingua franca alongside English in much of the interior, while Amharic, Somali and Malagasy dominate elsewhere. Many countries belong to the East African Community or the Common Market for Eastern and Southern Africa (COMESA), and intra-regional services, agriculture and tourism are central to the regional economy. Within that setting, The working official languages are swahili and english, and the legal-tender currency is the Tanzanian Shilling (TZS) (see Africa's currency arrangements).
The figures above are sourced from World Bank, IMF, UN agency and national statistics-office releases. Reported nominal GDP for Tanzania is about US$85 billion. Population growth is currently estimated at about 2.9% per year, which influences how quickly the labour force, school cohorts and urban demand shift over a decade. The longer-form note on what growth rate hides is on reading African demographic data. At an urbanisation rate of about 37%, Tanzania is still predominantly rural, with cities growing faster than the countryside. Life expectancy at birth is reported at 66.2 years, and the adult literacy rate at about 78% — figures that summarise decades of investment in health systems and basic education.
How to read these figures
Country indicators on Africa Center are point-in-time estimates that are revised when new census or survey data is published. GDP is reported here as nominal US dollars at current exchange rates, which is the format most widely used by international institutions for cross-country comparison; for the difference between this and the purchasing-power-parity variant, and why GDP rankings reorder between releases, see reading African economic data. Per-capita figures divide GDP by population and are most useful when read alongside the absolute total. Definitions for every indicator are in the glossary; the rules we follow when sources disagree are written up in the methodology.
