Argentina population pyramid 2026
Latin America and the Caribbean · South America
46,003,734 people in 2026 (projected). Argentina’s pyramid is now undercut at the base: births fell by more than a third after 2014, ending decades of fertility near three children per woman.

Argentina age distribution in 2026
Children under 15 account for 20.4% of the population, while 12.9% are aged 65 or older. The remaining 66.7% are in the conventional working-age range of 15–64. On these shares, the site classifies Argentina’s age structure as transitional; the guide to population pyramid types explains what that shape implies.
The total age dependency ratio is 49.9: about 50 people under 15 or 65+ for every 100 people aged 15–64 (30.6 children and 19.3 older people). This is an age-balance indicator, not a literal count of economic dependants per worker.
What shapes Argentina’s population pyramid
An early start and a long plateau
Argentina began its demographic transition earlier than most of Latin America. Mass immigration from Europe in the late nineteenth and early twentieth centuries and early urbanization meant that by 1950 fertility was already about 3.2 children per woman, when much of the region was near six. Unusually, it then stayed around three for four decades, into the 1990s.
That long plateau gives the 2026 pyramid a broad, even middle. Every band from 10–14 to 45–49 holds between 6.7% and 8.1% of the population, with no pronounced baby boom or bust. Above age 50 the bands taper steadily, and women increasingly outnumber men from about age 65. The pattern resembles that of Uruguay, which followed a similar early path.
A sudden fall in births
Fertility declined slowly after 1990, then abruptly. The UN estimates the rate at about 2.4 children per woman in 2010 and about 1.5 in 2023, and registered births fell by more than a third between 2014 and the early 2020s. Much of the drop came from fewer births to adolescents and young women. Researchers link it in part to wider access to contraception, including a national plan to prevent unintended adolescent pregnancy launched in 2017, though the relative weight of each factor is still debated.
The fall is written plainly into the base of the 2026 pyramid. The 10–14 band, born in 2012–16, is the widest male band; the 5–9 band, born in 2017–21, is about a sixth narrower, and the 0–4 band, born in 2022–26, about a third narrower than the 10–14 band. An undercut of this kind is explained in population growth vs fertility: the population still grows because the large plateau cohorts are at parenting ages, even though each woman has fewer children.
Under the UN medium scenario Argentina’s population peaks at about 48.3 million around 2050, a turning point shown in the population peak year ranking, and the Argentina 2050 pyramid is widest at ages 35–39 with a median age near 42.
What to notice across the years
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 Argentina’s 2026 pyramid has a comparatively smooth profile without sharp bulges or notches.
Births outnumber deaths in 2026; the medium scenario projects deaths to exceed births from 2050. People aged 65 and older are projected to outnumber children under 15 by 2045.
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, Argentina is projected to record 510,178 births (about 1,397 births a day) and 361,468 deaths, a natural increase of 148,710. Net migration adds +2,316 people, ranking #94 in the net migration rate ranking.
Between 2000 and 2023 the UN estimates 16,580,856 births, 7,820,020 deaths, and cumulative net migration of −149,638. 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 +19,704 between 2026 and 2050.

Women in Argentina are projected to live 5.0 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 72 to 8.5 deaths per 1,000 live births since 1950, ranking #129 of 237 in the infant mortality ranking (highest first). A mean age at childbearing of 29.3 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 Argentina
The median age of 33.3 years splits the population into two equal halves. A total fertility rate of 1.51 births per woman is below the replacement level of roughly 2.1, and life expectancy at birth is 77.8 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 | 46,003,734 | #35 | Largest first |
| Median age | 33.3 years | #120 | Oldest first |
| Fertility rate | 1.51 | #165 | Highest first |
| Annual growth | +0.3% | #155 | Fastest first |
| Life expectancy | 77.8 years | #89 | Highest first |
| Population aged 65+ | 12.9% | #96 | Highest share first |
Largest age groups in Argentina
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 | 10–14 | 3,727,914 | 8.1% | 1.9M / 1.8M |
| 2 | 15–19 | 3,635,157 | 7.9% | 1.9M / 1.8M |
| 3 | 30–34 | 3,506,174 | 7.6% | 1.8M / 1.7M |
| 4 | 25–29 | 3,469,201 | 7.5% | 1.8M / 1.7M |
| 5 | 20–24 | 3,467,334 | 7.5% | 1.8M / 1.7M |
Sex ratio and the balance by age
In the 2026 projection, Argentina has 22,843,960 males and 23,159,774 females. That is 98.6 males per 100 females, ranking #109 when the dataset is ordered from the highest male-to-female ratio to the lowest.
Males account for 49.7% of the population and females for 50.3%. There are 315,814 more females than males overall. Among people aged 65 and older, the ratio is 74.3 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, 105.0 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 Argentina has changed since 1950
The population has increased from 17,018,036 in 1950 to 46,003,734 in 2026, a change of 170%. Over the same span, median age moved from 24.4 to 33.3 years.
The under-15 share changed from 31.1% to 20.4%, while the share aged 65 and older changed from 4.1% to 12.9%. These shifts show why total population growth and age-structure change need to be read separately. See the Argentina population pyramid in 1950 for the full starting shape.
How the population could change by 2050
Under the UN medium scenario, Argentina’s population is projected to grow by about 5%, reaching 48,308,944 in 2050. The median age changes from 33.3 to 41.9 years.
The 65+ share is projected to rise by 7.0 percentage points to 19.9%. At the same time, the under-15 share is projected at 15.5%. The Argentina 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 48,308,944 in 2050. That turning point depends on the medium scenario and may move in later revisions. Compare timing across countries in the population peak ranking.
