About Nigeria
Nigeria is located in the bulge of the African continent that arcs from the Sahel southward to the Gulf of Guinea. Its capital is Abuja, and it covers roughly 923,768 square kilometres. The population of about 230.0 million makes it one of 16 countries that make up West Africa. Nigeria is the most populous country in West Africa, and the largest reported economy in the region. The country marks its modern statehood from 1960.
West Africa is the most populous of Africa's five regions and one of its most linguistically diverse — a colonial legacy of French and English coexists with hundreds of indigenous languages. Many West African countries are members of the Economic Community of West African States (ECOWAS) and several share the West African CFA franc as a common currency. Agriculture, mining, and services anchor most economies, with Nigeria as the dominant single economy by both population and GDP. Within that setting, The working official language is english, and the legal-tender currency is the Nigerian Naira (NGN) (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 Nigeria is about US$510 billion. Population growth is currently estimated at about 2.4% 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 54%, Nigeria is transitioning toward an urban majority. Life expectancy at birth is reported at 55.8 years, and the adult literacy rate at about 62% — 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.
