Nigeria population pyramid 2026

Africa · Western Africa

242,431,832 people in 2026 (projected). Nigeria has a textbook expansive pyramid: about 40% of people are under 15, and each age band is narrower than the one below it all the way up.

Estimate or projection?

The UN series provides historical estimates through 2023. Figures from 2024 onward—including 2026—are medium-scenario projections, not counts or predictions guaranteed to occur.

Nigeria age distribution in 2026

Children under 15 account for 40.0% of the population, while 3.1% are aged 65 or older. The remaining 56.9% are in the conventional working-age range of 15–64. On these shares, the site classifies Nigeria’s age structure as youthful; the guide to expansive population pyramids explains what that shape implies.

The total age dependency ratio is 75.8: about 76 people under 15 or 65+ for every 100 people aged 15–64 (70.3 children and 5.4 older people). This is an age-balance indicator, not a literal count of economic dependants per worker.

What shapes Nigeria’s population pyramid

A pyramid with straight, steep sides

Nigeria’s 2026 pyramid is close to the classroom ideal of an expansive pyramid. About 40% of the population is under 15, the median age is about 18, and every five-year band is smaller than the one beneath it, with no notches or bulges from wars or policy campaigns. Two forces produce this shape. Fertility remains high, at about 4.2 children per woman in the UN estimates, so each new birth cohort is larger than the last. Mortality is also high by global standards, with life expectancy around 55, so cohorts shrink noticeably as they age and the sides fall away steeply above age 40. People aged 65 and over make up only about 3% of the total.

Early signs of a turn

The base has begun to change. In 2000 the 0–4 band was about a quarter larger than the 5–9 band; in 2026 it is less than a tenth larger, because fertility has been falling slowly. The decline is uneven: Demographic and Health Surveys have consistently found much higher fertility in the northern states, especially the north-west, than in the south, so the national pyramid averages very different regional patterns. The India vs Nigeria comparison shows what a further fall in fertility does to a pyramid’s base, while Nigeria vs Japan sets the two extremes of age structure side by side.

Uncertain counts, strong momentum

Nigeria has not held a census since 2006, whose results were disputed, and a census planned for 2023 was postponed. Estimates of the age structure therefore lean heavily on household surveys, and the true population size is less certain than for most large countries. What is not in doubt is the population momentum: the children now aged 0–14 will reach parenthood over the next two decades, so the number of births keeps rising even as births per woman fall. The Nigeria 2100 pyramid shows the beehive shape the UN projects once fertility approaches replacement.

Under the UN medium scenario Nigeria grows to about 359 million people by 2050, with a median age near 24 and a base that has almost stopped widening.

What to notice across the years

Nigeria population pyramid 1975 (historical estimate)
1975. Children aged 0–4 make up over 18% of the population, giving the widest base in Nigeria’s series.
Nigeria population pyramid 2026 (UN medium projection)
2026. Every band is narrower than the one below; the step from 0–4 to 5–9 is smaller than it was in 2000.
Nigeria population pyramid 2100 (UN medium projection)
2100. Ages 20–29 are wider than ages 0–4: the projected pyramid turns into a beehive as fertility nears replacement.

Distinctive cohorts and turning points

No five-year band under age 80 is more than 10% larger or smaller than both of its neighbours, so Nigeria’s 2026 pyramid has a comparatively smooth profile without sharp bulges or notches.

In the UN medium scenario births outnumber deaths in every year through 2100. Children under 15 outnumber people aged 65 and older in every pyramid year through 2100.

Births, deaths, and migration

A pyramid changes in only three ways: births add to the base, deaths remove people at every age, and migration adds or removes people mainly in young adulthood. In 2026, Nigeria is projected to record 7,711,752 births (about one birth every 4.1 seconds) and 2,780,783 deaths, a natural increase of 4,930,969. Net migration adds −2,810 people, ranking #97 in the net migration rate ranking.

Between 2000 and 2023 the UN estimates 164,533,200 births, 59,012,749 deaths, and cumulative net migration of +77,060. Over that period the balance of births and deaths moved the total more than migration did. See how migration shapes a pyramid and birth rate versus fertility rate. The medium scenario assumes net migration of +893,038 between 2026 and 2050.

Women in Nigeria are projected to live 0.7 years longer than men, which is why the female side of the pyramid widens relative to the other at older ages (see the life expectancy gap ranking). Infant mortality has fallen from 163 to 66.9 deaths per 1,000 live births since 1950, ranking #2 of 237 in the infant mortality ranking (highest first). A mean age at childbearing of 29.1 years sets the spacing between generations, and so how far apart echo cohorts sit in the pyramid.

Median age, fertility rate, and global ranks for Nigeria

The median age of 18.3 years splits the population into two equal halves. A total fertility rate of 4.20 births per woman is above the replacement level of roughly 2.1, and life expectancy at birth is 55.0 years.

These ranks compare all 237 countries and areas in this dataset using the same 2026 UN medium projection. Ranks use the stored source precision, so displayed rounding can make adjacent values look identical; small differences should not be overinterpreted.

Largest age groups in Nigeria

The five largest cohorts identify where the 2026 population is concentrated. They can reflect past birth patterns, survival, and migration; the chart alone does not establish which cause dominates.

Sex ratio and the balance by age

In the 2026 projection, Nigeria has 122,708,307 males and 119,723,524 females. That is 102.5 males per 100 females, ranking #41 when the dataset is ordered from the highest male-to-female ratio to the lowest.

Males account for 50.6% of the population and females for 49.4%. There are 2,984,783 more males than females overall. Among people aged 65 and older, the ratio is 90.7 males per 100 females.

The overall balance can conceal large differences by age; how sex ratios change with age explains the usual pattern. The ratio reflects the male/female categories in the UN source and is not a measure of gender identity. Compare all profiles in the sex-ratio ranking.

At birth, 103.8 boys are projected to be born for every 100 girls in 2026, close to the biological norm of about 105 (compare the sex ratio at birth ranking). The ratio at birth sets the balance at the base of the pyramid; how it changes with age then depends on survival and migration.

How Nigeria has changed since 1950

The population has increased from 37,283,010 in 1950 to 242,431,832 in 2026, a change of 550%. Over the same span, median age moved from 18.1 to 18.3 years.

The under-15 share changed from 41.7% to 40.0%, while the share aged 65 and older changed from 3.0% to 3.1%. These shifts show why total population growth and age-structure change need to be read separately. See the Nigeria population pyramid in 1950 for the full starting shape.

How the population could change by 2050

Under the UN medium scenario, Nigeria’s population is projected to grow by about 48%, reaching 359,185,556 in 2050. The median age changes from 18.3 to 23.9 years.

The 65+ share is projected to rise by 1.4 percentage points to 4.5%. At the same time, the under-15 share is projected at 30.9%. The Nigeria population pyramid for 2050 shows the projected shape in detail. How UN projections work explains the assumptions behind these figures.

The population is still rising at the end of the UN medium projection in 2100, when it reaches 476,747,781. The page therefore does not assign a peak year beyond the available horizon.

Countries with the most similar age structure

These profiles have the 2026 age distributions closest to Nigeria’s, measured by the total difference in the share of the population in each five-year band. Similar shapes can arise from very different histories, so the match is a starting point for comparison, not an explanation.
