Algeria population pyramid 2026
48,028,334 people in 2026 (projected). Algeria’s pyramid has a pinched waist at ages 20–29, left by the 1990s fertility fall, between two wide generations born in the 1980s and after 2010.

Algeria age distribution in 2026
Children under 15 account for 29.4% of the population, while 7.0% are aged 65 or older. The remaining 63.5% are in the conventional working-age range of 15–64. On these shares, the site classifies Algeria’s age structure as transitional; the guide to population pyramid types explains what that shape implies.
The total age dependency ratio is 57.5: about 58 people under 15 or 65+ for every 100 people aged 15–64 (46.4 children and 11.1 older people). This is an age-balance indicator, not a literal count of economic dependants per worker.
What shapes Algeria’s population pyramid
From very high fertility to a sudden slowdown
Until the early 1980s Algerian women had on average about seven children, and in 1975 the median age was only about 15. Fertility then fell very rapidly: from about 7.0 in 1980 to 4.5 in 1990 and 2.6 by 2000. The Algeria 2000 pyramid records the change, with a base narrower than the two bands above it. The decline continued through the economic crisis and civil conflict of the 1990s, which may have reinforced it, while later marriage and wider schooling for women were pushing in the same direction.
A rebound in births after 2000
The unusual part of the story is what came next. Instead of continuing downward, the total fertility rate rose again to about 2.9 around 2010 and was still about 2.8 in 2023. In 2026 the three youngest bands, born roughly 2012–2026, are the widest in the pyramid, and each holds more than four million people. The small 1990s generation, born about 1997–2001, sits between them and the large cohorts of the 1980s: the 25–29 band is about 11% smaller than its neighbours, giving the pyramid a distinct waist rather than the smooth taper of a steadily ageing country. Part of the rebound in births is a simple numbers effect, since the large 1980s cohorts reached their main childbearing ages in the 2010s, a mechanism explained in the guide to population momentum.
Algeria’s current shape is closest to Mongolia and Kazakhstan, which also saw births recover after a downturn in the 1990s. Migration barely alters the outline: net emigration from 2000 to 2023 totalled about 570,000, small against roughly 20.7 million births over the same years.
Echoes in the projection
Because the rebound cohorts are so large, the medium scenario keeps the population growing for decades, to about 59.6 million in 2050 and a peak of about 65 million around 2090, with deaths not expected to outnumber births until 2092. The 1990s trough keeps moving up the pyramid: by 2050 it appears as a dip at ages 45–54, sandwiched between the wide post-2010 generation in its thirties and the 1980s cohorts approaching retirement. Older women already outnumber men, with about 77 men per 100 women at ages 80–84 in 2026, and the share aged 65 and over is projected to more than double to about 16% by 2050.
What to notice across the years
Distinctive cohorts and turning points
Comparing each five-year band with its neighbours picks out the cohorts that break a smooth slope. These irregularities usually record past surges or deficits in births, or migration concentrated at particular ages; the pattern alone does not identify which. The guide to baby booms and echo cohorts explains how to date and interpret them.
| Age band in 2026 | Born about | Feature | Versus neighbouring bands |
|---|---|---|---|
| 25–29 | 1997–2001 | Notch (smaller cohort) | −11% |
Births outnumber deaths in 2026; the medium scenario projects deaths to exceed births from 2092. People aged 65 and older are projected to outnumber children under 15 by 2065.
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, Algeria is projected to record 832,197 births (about one birth every 38 seconds) and 224,898 deaths, a natural increase of 607,299. Net migration adds −28,841 people, ranking #138 in the net migration rate ranking.
Between 2000 and 2023 the UN estimates 20,723,878 births, 4,347,551 deaths, and cumulative net migration of −567,839. 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 −747,350 between 2026 and 2050.

Women in Algeria are projected to live 2.8 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 170 to 15.8 deaths per 1,000 live births since 1950, ranking #74 of 237 in the infant mortality ranking (highest first). A mean age at childbearing of 31.4 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 Algeria
The median age of 28.8 years splits the population into two equal halves. A total fertility rate of 2.62 births per woman is above the replacement level of roughly 2.1, and life expectancy at birth is 76.9 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.
| Indicator | 2026 value | Global rank | Ranking direction |
|---|---|---|---|
| Population | 48,028,334 | #32 | Largest first |
| Median age | 28.8 years | #148 | Oldest first |
| Fertility rate | 2.62 | #68 | Highest first |
| Annual growth | +1.2% | #83 | Fastest first |
| Life expectancy | 76.9 years | #105 | Highest first |
| Population aged 65+ | 7.0% | #145 | Highest share first |
Largest age groups in Algeria
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.
| Rank | Age group | Population | Share of total | Male / female |
|---|---|---|---|---|
| 1 | 5–9 | 4,932,815 | 10.3% | 2.5M / 2.4M |
| 2 | 10–14 | 4,829,527 | 10.1% | 2.5M / 2.4M |
| 3 | 0–4 | 4,379,228 | 9.1% | 2.2M / 2.1M |
| 4 | 15–19 | 4,025,591 | 8.4% | 2.1M / 2M |
| 5 | 40–44 | 3,661,991 | 7.6% | 1.9M / 1.8M |
Sex ratio and the balance by age
In the 2026 projection, Algeria has 24,484,793 males and 23,543,540 females. That is 104.0 males per 100 females, ranking #29 when the dataset is ordered from the highest male-to-female ratio to the lowest.
Males account for 51.0% of the population and females for 49.0%. There are 941,253 more males than females overall. Among people aged 65 and older, the ratio is 93.9 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, 104.6 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 Algeria has changed since 1950
The population has increased from 9,018,426 in 1950 to 48,028,334 in 2026, a change of 433%. Over the same span, median age moved from 18.4 to 28.8 years.
The under-15 share changed from 40.6% to 29.4%, while the share aged 65 and older changed from 3.5% to 7.0%. These shifts show why total population growth and age-structure change need to be read separately. See the Algeria population pyramid in 1950 for the full starting shape.
How the population could change by 2050
Under the UN medium scenario, Algeria’s population is projected to grow by about 24%, reaching 59,565,554 in 2050. The median age changes from 28.8 to 34.5 years.
The 65+ share is projected to rise by 9.2 percentage points to 16.2%. At the same time, the under-15 share is projected at 21.0%. The Algeria population pyramid for 2050 shows the projected shape in detail. How UN projections work explains the assumptions behind these figures.
The annual UN series reaches its highest projected population of 65,115,474 in 2090. That turning point depends on the medium scenario and may move in later revisions. Compare timing across countries in the population peak ranking.
