• Source: Demographics of Nigeria

Nigeria is the most populous country in Africa and the sixth most populous in the world. It is also one of the most densely populated countries in Africa, with approximately 218.5 million people in an area of 923,768 km2 (356,669 sq mi).
54.3% of Nigerians are urban dwellers, with the annual rate of urbanisation being estimated at 3.92%. Nigeria is home to 371 ethnic groups speaking over 500 languages and the variety of customs and traditions among them gives the country great cultural diversity. Three largest ethnic groups, namely the Hausa, Yorubas, and Igbos constitue more than 60% of the population. The Ijaw, Efik, Ibibio, Annang, Ogoni, Tiv, Urhobo-Isoko, Edo and Itsekiri are some of the other sizeable ethnic groups. Over 1.2 million people living in Nigeria (0.5% of its total population, or 1 in every 200 people living in Nigeria) are from a continent other than Africa. There are 100,000 people from the United States, 75,000 are from Lebanon, 60,000 are from China and 16,000 are from the United Kingdom.
Nigeria has a young population overall, with 42.54% of inhabitants between the ages of 0–14. There is also a very high dependency ratio at 88.2 dependants per 100 non-dependants. The three main religious groups are Muslims (estimated to be 53.5% of the total population), Christians (estimated at 45.9%), and adherents of indigenous religions (estimated at 0.6%). The predominantly Christian Igbo are found in the southeast. Roman Catholicism is the largest Christian denomination in Igboland, but Anglicanism is also strong, as are Pentecostalism and other Evangelical denominations.
Persons of different ethnic backgrounds most commonly communicate in English, although knowledge of two or more Nigerian languages is widespread. Hausa, Igbo and Yoruba are the most widely used Nigerian languages. Nigerian Pidgin is used widely as an unofficial medium of communication, especially in the Nigerian cities of Warri, Sapele, Ughelli, Benin, and Port Harcourt.




Population



Nigeria's population has been increasing rapidly for at least the last 5 decades due to very high birth rates, quadrupling its population during this time. Growth was fastest in the 1980s, after child mortality dropped rapidly. It has slowed slightly since then as both the birth rate and total fertility, rate have declined marginally since a 1978 peak. According to the 2017 revision of the World Population Prospects the total population was 257,541,212 in 2016, compared to only 88,992,220 in 1950. The proportion of children under the age of 15 in 2010 was 44.0%, 53.2% were between 15 and 65 years of age, while 2.7% were 65 years or older. There is a large degree of population momentum, with 3.2 per cent growth leading to the projected population of 546 million by 2100.
The federal government has not elected to implement the type of controversial family planning programs that have reduced population growth of other developing nations, a result of low political support for these programs and a cultural preference for large families as well as high levels of social instability. Rising educational levels and health care improvements may enable future parents to plan for smaller families.
The former Nigeria's chairman of National Population Commission, Eze Duruiheoma, delivering Nigeria's statement in New York City on sustainable cities, human mobility and international migration in the 51st session of Commission on Population and Development, said that "Nigeria remains the most populous in Africa, the seventh globally with an estimated population of over 198 million. The World Population Prospects predicts that by 2050, Nigeria will become the third most populated country in the world. Over the last 50 years, Nigeria's urban population has grown at an average annual growth rate of more than 6.5% without commensurate increases in social amenities and infrastructure." He also stated that the population "grew substantially from 17.3% in 1967 to 49.4% in 2017."

Population projections


The total population in sub-Saharan Africa is projected to increase to almost one billion people, making it the most populated region outside of South-Central Asia. According to the United Nations, the population of Nigeria will reach 375 million by 2050. Nigeria might then be the 3rd most populous country in the world. In 2100, the population of Nigeria may reach 541 million. While the overall population is expected to increase, the growth rate is estimated to decrease from 1.2 per cent per year in 2010 to 0.4 per cent per year in 2050. The birth rate is also projected to decrease from 20.7 to 13.7, while the death rate is projected to increase from 8.5 in 2010 to 9.8 in 2050. By 2050, 69.6% of the population is estimated to be living in urban areas compared to 50.6% in 2010.

Note 1: on 30 September 2021, the Centers for Disease Control and Prevention issued a Travel Health Notice for a Yellow Fever outbreak in Nigeria; a large, ongoing outbreak of yellow fever in Nigeria began in September 2017; the outbreak is now spread throughout the country with the Nigerian Ministry of Health reporting cases of the disease in multiple states (Bauchi, Benue, Delta, Ebonyi, and Enugu); the CDC recommends travellers going to Nigeria should receive vaccination against yellow fever at least 10 days before travel and should take steps to prevent mosquito bites while there; those never vaccinated against yellow fever should avoid travel to Nigeria during the outbreak
Note 2: widespread ongoing transmission of a respiratory illness caused by the novel coronavirus (COVID-19) is occurring throughout Nigeria; as of 6 June 2022, Nigeria has reported a total of 256,148 cases of COVID-19 or 124.3 cumulative cases of COVID-19 per 100,000 population with a total of 3,148 cumulative deaths or a rate of 1.5 cumulative death per 100,000 population; as of 22 May 2022, 12.97% of the population has received at least one dose of COVID-19 vaccine
Note 3: on 21 March 2022, the US Centers for Disease Control and Prevention (CDC) issued a Travel Alert for polio in Africa; Nigeria is currently considered a high risk to travellers for circulating vaccine-derived polioviruses (cVDPV); vaccine-derived poliovirus (VDPV) is a strain of the weakened poliovirus that was initially included in oral polio vaccine (OPV) and that has changed over time and behaves more like the wild or naturally occurring virus; this means it can be spread more easily to people who are unvaccinated against polio and who come in contact with the stool or respiratory secretions, such as from a sneeze, of an “infected” person who received oral polio vaccine; the CDC recommends that before any international travel, anyone unvaccinated, incompletely vaccinated, or with an unknown polio vaccination status should complete the routine polio vaccine series; before travel to any high-risk destination, CDC recommends that adults who previously completed the full, routine polio vaccine series receive a single, lifetime booster dose of polio vaccine

Emigration



Today millions of ethnic Nigerians live abroad, the largest communities can be found in the United Kingdom (500,000–3,000,000) and the United States (600,000–1,000,000 Nigerians), other countries that followed closely are South Africa, Gambia, and Canada respectively. There are also large groups in Ireland, Portugal and many other countries.
Inspiration for emigration is based heavily on socio-economical issues such as warfare, insecurity, economical instability and civil unrest.
Between 1400 and 1900, of 1.4 million of 2 million emigrants were slaves sent to the Americas with the other 600,000 being sent to other destinations via the trans-Saharan, Red Sea and Indian Ocean routes. This is due to the fact that the land now known as Nigeria was a central point for 4 slave trades during the 19th century. Though bondage represented a great deal, an estimated 30,000 Nigerian inhabitants would relocate to Kano City and Gambia to take advantage of financial opportunities afforded by fertile land and available natural resources. What's more, the presence of gold mines and rail lines along the Gold Coast, present-day Ghana, attracted an estimated 6,500 Nigerian citizens to attain financial gain and opportunity. The population of Nigerians in Ghana rose to roughly 149,000 before the 1969 alien expulsion order would displace nearly the entire population to surrounding countries.




Religion



Nigeria is nearly equally divided between Islam and Christianity. The majority of Nigerian Muslims are Sunni and mostly live in the northern, central and south-western states of the country, while Christians dominate in some central states (especially Plateau and Benue states), and the south-east and south-south regions. Other religions practised in Nigeria include African Traditional Religion, Hinduism, Baháʼí Faith, Judaism, The Grail Movement, and the Reformed Ògbóni Fraternity, one of the traditional socio-religious institutions of the Yorùbá people and their Òrìṣà religion known as Ẹ̀sìn Òrìṣà Ìbílẹ̀ in the Yorùbá language.
According to a 2009 Pew survey, 50.4% of Nigeria's population were Muslims. A later Pew study in 2011 calculated that Christians now formed 50.8% of the population. Adherents of other religions made up 1% of the population.
The shift of population balance between Muslims and Christians is a result of northern and southern Nigeria being in different stages of demographic transition. The Muslim-dominated north is in an earlier stage of the demographic transition with much higher fertility rates than the south, whose split Christian/Muslim population is further along in the transition, and whose fertility rates are declining. Decreasing fertility can be linked to more access to education, use of contraceptives, and differing beliefs regarding family planning.
The 1999 introduction of Sharia law in twelve northern Nigerian states led to massive violence and unrest and caused an ethnic and religious rift between Sharia and Non-Sharia states, a divide that has deepened with time.




Crime



Nigeria is home to a substantial network of organised crime, active especially in drug trafficking.
Nigerian criminal groups are heavily involved in drug trafficking, shipping heroin from Asian countries to Europe and America; and cocaine from South America to Europe and South Africa.
The various Nigerian confraternities or "campus cults" are active in both organised crime and in political violence as well as providing a network of corruption within Nigeria. As confraternities have extensive connections with political and military figures, they offer excellent alumni networking opportunities. The Supreme Vikings Confraternity, for example, boasts that twelve members of the Rivers State House of Assembly are cult members.
On lower levels of society, there are the "area boys", these are organised gangs mostly active in Lagos who specialise in mugging and small-scale drug dealing. According to official statistics, gang violence in Lagos resulted in 273 civilians and 84 policemen killed in the period of August 2000 to May 2001.
"The result of factors such as endemic local corruption, which facilitates illicit trafficking; the Nigerian Civil War, which contributed to a proliferation of firearms; the oil boom of the 1970s, which led to the embezzlement of public funds; and the economic crisis of the 1980s, which was accompanied by a rise in robberies. The expansion of the Nigerian diaspora and organized crime went hand in hand. Global migration boosted prostitution, drug trafficking and fraud, the three main activities of Nigerian syndicates. The smuggling of Nigerian sex workers became a whole industry that now extends from Switzerland to France and Italy (where black prostitutes are called "fireflies"), and has even reached the Prudish Kingdom of Saudi Arabia, from which 1,000 women are said to be deported every month by the authorities."
The high crime rate among Nigerian migrants also leads to stereotyping Nigerians as criminals; thus, in Cameroon, Nigerian migrants are perceived collectively by the inhabitants of Cameroon as likely to be oil smugglers or dealers in stolen cars. In the Netherlands, the debate on Nigerian crime reached an intensity described as a "moral panic" by one scholar. In Switzerland, the crime rate of Nigerian young males was reported as 620% that of Swiss males in same age group (2009 data), the second highest crime rate of any nationality, just below that of Angolan nationals (at 630%).
Nigeria is also pervaded by political corruption. It is ranked 136 out of 168 countries in Transparency International's 2015 Corruption Perceptions Index.
