American Samoa population pyramid 2026
45,318 people in 2026 (projected). American Samoa’s pyramid has a deep gap in the late twenties, as young adults move to the United States; the population has shrunk by about a fifth since 2002.

American Samoa age distribution in 2026
Children under 15 account for 25.7% of the population, while 9.1% are aged 65 or older. The remaining 65.3% are in the conventional working-age range of 15–64. On these shares, the site classifies American Samoa’s age structure as transitional; the guide to population pyramid types explains what that shape implies.
The total age dependency ratio is 53.2: about 53 people under 15 or 65+ for every 100 people aged 15–64 (39.3 children and 13.9 older people). This is an age-balance indicator, not a literal count of economic dependants per worker.
What shapes American Samoa’s population pyramid
A territory that exports its young adults
American Samoans are US nationals and can move freely to Hawaii and the US mainland, and many do, for work, study and military service, which is a common path for young people from the territory. Net migration removed about 31,000 people between 2000 and 2023, more than half the population of about 57,000 at its 2002 peak. In 2026 the territory still loses about 1,000 people a year to migration, more than the natural increase of about 300.
The result is a pyramid with a full base of children and teenagers and a sharp notch above it. The 25–29 band, born about 1997–2001, is about 26% smaller than its neighbours, and the 15–19 band is roughly twice its size. Because the population is small, individual bands are noisy, but a gap this large is consistent with the migration figures. The medium scenario carries it forward, and by 2050 the cohort forms a notch at 50–54.
Fertility has fallen from about 6.6 children per woman in 1960 to about 2.2, and the age structure now resembles those of Venezuela and Lebanon, two other populations shaped by heavy emigration. Under the medium scenario the population falls to about 37,500 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) | −26% |
Births outnumber deaths in 2026; the medium scenario projects deaths to exceed births from 2054. People aged 65 and older are projected to outnumber children under 15 by 2075.
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, American Samoa is projected to record 657 births (about 2 births a day) and 350 deaths, a natural increase of 307. Net migration adds −1,004 people, ranking #233 in the net migration rate ranking.
Between 2000 and 2023 the UN estimates 28,676 births, 6,829 deaths, and cumulative net migration of −31,394. Over that period migration moved the total more than the balance of births and deaths did. See how migration shapes a pyramid and birth rate versus fertility rate. The medium scenario assumes net migration of −12,620 between 2026 and 2050.
Annual values 1950–2100; dashed lines after 2023 are the UN medium projection. The trend table below lists the values by decade.

Women in American Samoa are projected to live 5.8 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 74 to 7.9 deaths per 1,000 live births since 1950, ranking #140 of 237 in the infant mortality ranking (highest first). A mean age at childbearing of 29.5 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 American Samoa
The median age of 29.1 years splits the population into two equal halves. A total fertility rate of 2.22 births per woman is above the replacement level of roughly 2.1, and life expectancy at birth is 73.3 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 | 45,318 | #213 | Largest first |
| Median age | 29.1 years | #144 | Oldest first |
| Fertility rate | 2.22 | #91 | Highest first |

| Life expectancy | 73.3 years | #146 | Highest first |
| Population aged 65+ | 9.1% | #124 | Highest share first |
Largest age groups in American Samoa
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, American Samoa has 22,823 males and 22,496 females. That is 101.5 males per 100 females, ranking #56 when the dataset is ordered from the highest male-to-female ratio to the lowest.
Males account for 50.4% of the population and females for 49.6%. There are 327 more males than females overall. Among people aged 65 and older, the ratio is 86.8 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, 106.0 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 American Samoa has changed since 1950
The population has increased from 19,042 in 1950 to 45,318 in 2026, a change of 138%. Over the same span, median age moved from 15.5 to 29.1 years.
The under-15 share changed from 46.3% to 25.7%, while the share aged 65 and older changed from 2.3% to 9.1%. These shifts show why total population growth and age-structure change need to be read separately.
How the population could change by 2050
Under the UN medium scenario, American Samoa’s population is projected to decline by about 17%, reaching 37,545 in 2050. The median age changes from 29.1 to 35.6 years.
The 65+ share is projected to rise by 9.7 percentage points to 18.8%. At the same time, the under-15 share is projected at 21.1%. How UN projections work explains the assumptions behind these figures.
The annual UN series reaches its highest estimated population of 57,062 in 2002. Historical population totals are estimates rather than exact head counts. Compare timing across countries in the population peak ranking.
