Nigeria - Demographics

Demographics

Population in Nigeria increased from 1990 to 2008 with 57 million and 60% growth in population. Nigeria is the most populous country in Africa and accounts for about 18% of the continent's total population, however, exactly how populous is a subject of speculation. The United Nations estimates that the population in 2009 was at 154,729,000, distributed as 51.7% rural and 48.3% urban, and with a population density of 167.5 people per square kilometer. National census results in the past few decades have been disputed. The results of the most recent census were released in December 2006 and gave a population of 140,003,542. The only breakdown available was by gender: males numbered 71,709,859, females numbered 68,293,08. On June 2012, President Goodluck Jonathan said that Nigerians should limit their number of children.

According to the United Nations, Nigeria has been undergoing explosive population growth and one of the highest growth and fertility rates in the world. By their projections, Nigeria is one of eight countries expected to account collectively for half of the world's total population increase from 2005–2050. By 2100 the UN estimates that the Nigerian population will be between 505 million and 1.03 billion people (middle estimate: 730 million). In 1950, Nigeria had only 33 million people.

According to current data, one out of every four Africans is Nigerian. Presently, Nigeria is the seventh most populous country in the world, and even conservative estimates conclude that more than 20% of the world's black population lives in Nigeria. 2006 estimates claim 42.3% of the population is between 0–14 years of age, while 54.6% is between 15–65; the birth rate is significantly higher than the death rate, at 40.4 and 16.9 per 1000 people respectively.

Health, health care, and general living conditions in Nigeria are poor. Life expectancy is 47 years (average male/female) and just over half the population has access to potable water and appropriate sanitation; the percentage is of children under five has gone up rather than down between 1990 and 2003 and infant mortality is 97.1 deaths per 1000 live births. HIV/AIDS rate in Nigeria is much lower compared to the other African nations such as Kenya or South Africa whose prevalence (percentage) rates are in the double digits. In 2003, the HIV prevalence rate among 20 to 29 year-olds was 5.6%. Nigeria suffers from periodic outbreaks of cholera, malaria, and sleeping sickness. It is the only country in Africa to have never eradicated polio, which it periodically exports to other African countries. A 2004 vaccination drive, spearheaded by the W.H.O. to combat polio and malaria, met with some opposition in the north, but polio was cut 98% between 2009 and 2010.

Education is in a state of neglect. After the 1970s oil boom, tertiary education was improved so that it would reach every subregion of Nigeria. Education is provided free by the government, but the attendance rate for secondary education is only 29% (32% for males, 27% for females). The education system has been described as "dysfunctional" largely because of decaying institutional infrastructure. 68% of the population is literate, and the rate for men (75.7%) is higher than that for women (60.6%).

Nigeria's largest city is Lagos. Lagos has grown from about 300,000 in 1950 to an estimated 15 million today, and the Nigerian government estimates that city will have expanded to 25 million residents by 2015.
