Nigeria in the context of "Apapa"

Dhokra (also spelt Dokra) is non–ferrous metal casting using the lost-wax casting technique. This sort of metal casting has been used in India for over 4,000 years and is still used. One of the earliest known lost wax artifacts is the dancing girl of Mohenjo-daro. The product of dhokra artisans are in great demand in domestic and foreign markets because of primitive simplicity, enchanting folk motifs and forceful form. Dhokra horses, elephants, peacocks, owls, religious images, measuring bowls, and lamp caskets etc., are highly appreciated. The lost wax technique for casting of copper based alloys has also been found in China, Egypt, Malaysia, Nigeria, Central America, and other places.

The following is a list of the 100 largest cities in Africa by urban population using the most recent official estimate. This reflects only cities located geographically in Africa including related islands.

A minister is a politician who heads a ministry, making and implementing decisions on policies in conjunction with the other ministers. In some jurisdictions the head of government is also a minister and is designated the 'prime minister', 'premier', 'chief minister', 'chancellor' or other title.

In Commonwealth realm jurisdictions which use the Westminster system of government, ministers are usually required to be members of one of the houses of Parliament or legislature, and are usually from the political party that controls a majority in the lower house of the legislature. In other jurisdictions—such as Belgium, Mexico, Netherlands, Philippines, Slovenia, and Nigeria—the holder of a cabinet-level post or other government official is not permitted to be a member of the legislature. Depending on the administrative arrangements in each jurisdiction, ministers are usually heads of a government department and members of the government's ministry, cabinet and perhaps of a committee of cabinet. Some ministers may be more senior than others, and some may hold the title 'assistant minister' or 'deputy minister'. Some jurisdictions, with a large number of ministers, may designate ministers to be either in the inner or outer ministry or cabinet.

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 2017 is estimated at more than 1.25 billion, with a growth rate of more than 2.5% p.a. The most populous African country is Nigeria with 191 million inhabitants as of 2017 and a growth rate of 2.6% p.a.

Africa has a large quantity of natural resources, including diamonds, sugar, salt, gold, iron, cobalt, uranium, copper, bauxite, silver, petroleum, natural gas and cocoa beans, but also tropical timber and tropical fruit.

Recently discovered oil reserves have increased the importance of the commodity in African economies. Nigeria, Angola, Republic of the Congo, Equatorial Guinea, Algeria, Libya, Egypt, and South Sudan are among the largest oil producers in Africa. The United States and European countries took most of the Democratic Republic of the Congo's (DRC) oil production. Oil is provided by both continental and offshore productions. Sudan's oil exports in 2010 are estimated by the United States Department of State at US$9 billion.

Child care, also known as day care, is the care and supervision of one or more children, typically ranging from three months to 18 years old. Although most parents spend a significant amount of time caring for their child(ren), childcare typically refers to the care provided by caregivers who are not the child's parents. Childcare is a broad topic that covers a wide spectrum of professionals, institutions, contexts, activities, and social and cultural conventions. Early childcare is an essential and often overlooked component of child development.

A variety of people and organizations can care for children. The child's extended family may also take on this caregiving role. Another form of childcare is center-based childcare. In lieu of familial caregiving, these responsibilities may be given to paid caretakers, orphanages, or foster homes to provide care, housing, and schooling.

A planned community, planned city, planned town, or planned settlement is any community that was carefully planned from its inception and is typically constructed on previously undeveloped land. This contrasts with settlements that evolve organically.

The term new town refers to planned communities of the new towns movement in particular, mainly in the United Kingdom. It was also common in the European colonization of the Americas to build according to a plan either on fresh ground or on the ruins of earlier Native American villages.

A megacity is a very large city, typically with a population of more than 10 million people. The United Nations Department of Economic and Social Affairs (UN DESA) in its "World Urbanization Prospects" report defines megacities as urban agglomerations with over 10 million inhabitants. A University of Bonn report holds that they are "usually defined as metropolitan areas with a total population of 10 million or more people". Elsewhere in other sources, from five to eight million is considered the minimum threshold, along with a population density of at least 2,000 per square kilometre. The terms conurbation, metropolis, and metroplex are also applied to the latter.

The total number of megacities in the world varies between different sources and their publication dates. The world had 32 according to EU Global Human Settlement Layer (in 2024), 33 according to UN DESA (in 2025), 39 according to the OECD, 42 according to Demographia (in 2025), and 45 according to CityPopulation.de (in 2023). The later two add 13 additional cities that are calculated outside the range otherwise. In total, at most 53 unique places are mentioned as megacities across these sources, although some of these are just agglomerated differently between them. A good percentage of these urban agglomerations are in China and India. The other three-to-five countries with more than one megacity are Brazil, Indonesia, Japan, Pakistan, and the United States. African megacities are present in Angola, Democratic Republic of the Congo, Egypt, Nigeria and South Africa; European megacities are present in France, Germany, Russia, the United Kingdom, and Turkey (also in Asia); megacities can be found in Latin America in the countries of Brazil, Mexico, Colombia, Peru, and Argentina.

A triple border, tripoint, trijunction, triple point, or tri-border area is a geographical point at which the boundaries of three countries or subnational entities meet. There are 175 international tripoints as of 2020. Nearly half are situated in rivers, lakes or seas. On dry land, the exact tripoints may be indicated by markers or pillars, and occasionally by larger monuments.

Usually, the more neighbours a country has, the more international tripoints that country has. China with 16 international tripoints and Russia with 11 to 14 lead the list of states by number of international tripoints. Other countries, like Brazil, India, and Algeria, have several international tripoints. Argentina has four international tripoints. South Africa, Pakistan and Nigeria have three international tripoints, Guatemala has two: one with Mexico and Belize, and one with Honduras and El Salvador; while Bangladesh and Mexico have one. Within Europe, landlocked Austria has nine tripoints, among them two with Switzerland and Liechtenstein. Island countries, such as Japan and Australia, generally have no international tripoints, although some, like Bahrain and Singapore, have tripoints in their territorial waters. Countries with only one neighbouring country, such as Portugal or Lesotho, also have no international tripoints. Landlocked countries also have international tripoints. Likewise, the United States with two neighbouring countries has no international tripoints; however, it has a number of state tripoints as well as one point where four states meet. Indonesia has no international tripoints, just like Australia, Japan and the United States. Canada, as well, which has a maritime border with two other countries, has no international tripoints; however, it has five tripoints on land where the boundaries of provinces and territories meet, and one quadripoint where four provinces and territories meet. Japan has multiple prefectural tripoints; it also has prefectural quadripoints. In addition to the United States, Canada and Indonesia, Australia also has tripoints where the boundaries of states meet.

The number of languages natively spoken in Africa is variously estimated (depending on the delineation of language vs. dialect) at between 1,250 and 2,100, and by some counts at over 3,000. Nigeria alone has over 500 languages (according to SIL Ethnologue), 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:

• Niger–Congo, which include the large Atlantic-Congo and Bantu branches in West, Central, Southeast and Southern Africa.
• Afroasiatic languages are spread throughout Western Asia, North Africa, the Horn of Africa and parts of the Sahel.
• Saharan, Nilotic and Central Sudanic languages (grouped under the hypothetical Nilo-Saharan macro-family), are present in East Africa and Sahel.
• Austronesian languages are spoken in Madagascar and parts of the Comoros.
• Khoe–Kwadi languages are spoken mostly in Namibia and Botswana.
• Indo-European languages, while not indigenous to Africa, are spoken in South Africa and Namibia (Afrikaans, English, German) and are used as lingua francas in Liberia and the former colonies of the United Kingdom (English), former colonies of France and of Belgium (French), former colonies of Portugal (Portuguese), former colonies of Italy (Italian), former colonies of Spain (Spanish) and the current Spanish territories of Ceuta, Melilla and the Canary Islands and the current French territories of Mayotte and La Réunion.

There are several other small families and language isolates, as well as creoles and languages that have yet to be classified. In addition, Africa has a wide variety of sign languages, many of which are language isolates.
