[TREND] (Technical Terms & Definitions Below)
Nigeria's population increased by 57 million from 1990 to 2008, a 60% growth rate in less than two decades. As of 2017, the population stood at 191 million. Around 42.5% of the population were 14 years or younger, 19.6% were aged 15-24, 30.7% were aged 25-54, 4.0% aged 55-64, and 3.1% aged 65 years or older. The median age in 2017 was 18.4 years. Nigeria is the most populous country in Africa and accounts for about 17% of the continent's total population as of 2017; however, exactly how populous is a subject of speculation.
The United Nations estimates that the population in 2018 was at 195,874,685, distributed as 51.7% rural and 48.3% urban, and with a population density of 167.5 people per square kilometre. 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 68,293,008. In June 2012, President Goodluck Jonathan said Nigerians should limit their number of children.
According to the United Nations, Nigeria has been undergoing explosive population growth and has 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 in 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.
One in six Africans is Nigerian as of 2019. Presently, Nigeria is the seventh most populous country in the world. The birth rate is 35.2-births/1,000 population and the death rate is 9.6 deaths/1,000 population as of 2017, while the total fertility rate is 5.07 children born/woman.
Nigeria's largest city is Lagos. Lagos has grown from about 300,000 in 1950 to an estimated 13.4 million in 2017.
[TECHNICAL TERMS & DEFINITIONS]
*AGE STRUCTURE (POPULATION PYRAMID)
The composition of a population as determined by the number or proportion of males and females in each age category. The age-sex structure of a population is the cumulative result of past trends in fertility, mortality, and migration.
**POPULATION GROWTH RATE
The number of people added to (or subtracted from) a population in a year due to natural increase and net migration expressed as a percentage of the population at the beginning of the time period.
***TOTAL FERTILITY RATE (TFR)
The average number of children that would be born alive to a woman (or group of women) during her lifetime if she were to pass through her childbearing years conforming to the age-specific fertility rates of a given year.
****POTENTIAL SUPPORT RATIO
A number of people age 15-64 per one older person aged 65 or older. This ratio describes the burden placed on the working population (unemployment and children are not considered in this measure) by the non-working elderly population.
*****RATE OF NATURAL INCREASE (RNI)
The rate of natural increase refers to the difference between the number of live births and the number of deaths occurring in a year, divided by the mid-year population of that year, multiplied by a factor (usually 1,000).
It is equal to the difference between the crude birth rate and the crude death rate. This measure of the population change excludes the effects of migration.
