This article is about the demographic features of the population of Nigeria, including population density, ethnicity, education level, health of the populace, economic status, religious affiliations and other aspects of the population. The most populous country in Africa, Nigeria accounts for approximately one sixth of the African population (or one fifth of the Sub-Saharan African population). Approximately 50% of Nigerians are urban dwellers. At least 24 cities have populations of more than 100,000. The variety of customs, languages, and traditions among Nigeria's 389 ethnic groups gives the country a cultural diversity. Census figures are used to determine regional funding and representation of ethnic and religious groups in government service. This provides an incentive for inflating local populations. On the other hand, some academics believe the figures given below by the Food and Agriculture Organisation (FAO) are a serious underestimate. The most numerous ethnic groups in the northern two-thirds of the country are the Hausa and the Fulbe/Fulani, the overwhelming majority of whom are Muslim. Other major ethnic groups of the north are the Nupe, Tiv, and Kanuri. The Yoruba people are the overwhelming majority in the southwest, as well as parts of the north-central region. Over half of the Yorubas are Christian and about 40% are Muslim, while the remainder hold traditional Yoruba views. The predominantly Christian Igbo are to be found in the central parts of the southeast. Roman Catholicism is the largest Christian denomination, but Anglicanism is also strong, as are Pentecostal and other Evangelical denominations. The Efik, Ibibio, Annang, and Ijaw constitute other southeastern populations. Persons of different language backgrounds most commonly communicate in English, although knowledge of two or more Nigerian languages is widespread. Hausa, Yoruba, and Igbo are the most widely used native Nigerian languages. ==Population== 174,507,539 (July 2013 est.) (CIA World Factbook) 162,471,000 (July 2011 United Nations est.) Nigeria has experienced a population explosion for at least the last 50 years due to very high fertility rates, quadrupling its population during this time. Growth was fastest in the 1980s, after child mortality had dropped sharply, and has slowed slightly since then as the birth rate has sunk slightly. According to the 2012 revison of the World Population Prospects the total population was 159,708,000 in 2010, compared to only 37,860,000 in 1950. The proportion of children below the age of 15 in 2010 was 44.0%, 53.2% was between 15 and 65 years of age, while 2.7% was 65 years or older.〔(Population Division of the Department of Economic and Social Affairs of the United Nations Secretariat, World Population Prospects: The 2012 Revision ) 〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Demographics of Nigeria」の詳細全文を読む スポンサード リンク
