Micronesia population pyramid 2026
114,182 people in 2026 (projected). Micronesia’s pyramid has a young base but thins sharply from about age 30 up, as free migration to the United States drains working-age adults.

Micronesia age distribution in 2026
Children under 15 account for 31.2% of the population, while 6.4% are aged 65 or older. The remaining 62.5% are in the conventional working-age range of 15–64. On these shares, the site classifies Micronesia’s age structure as transitional; the guide to population pyramid types explains what that shape implies.
The total age dependency ratio is 60.1: about 60 people under 15 or 65+ for every 100 people aged 15–64 (49.9 children and 10.2 older people). This is an age-balance indicator, not a literal count of economic dependants per worker.
What shapes Micronesia’s population pyramid
Births up, population flat
The Federated States of Micronesia had about 112,000 inhabitants in 2000 and almost exactly the same number in 2023. Over those years there were about 68,000 births and only 19,000 deaths, so the lack of growth is almost entirely the result of emigration: a net outflow of about 48,000 people. Since the Compact of Free Association with the United States came into force in 1986, Micronesian citizens have been able to live and work in the US without a visa, and many have moved to Guam, Hawaii and the mainland. The Marshall Islands, which has a similar compact, has also seen heavy emigration to the US.
The departures are concentrated among young adults, so the pyramid narrows quickly above the late teens. In 2000 the 25–29 band was only about 60% the size of the 15–19 band; in 2026 the bands from 35 upward are less than two-thirds the width of those under 30, the outline of cohorts thinned by decades of leaving. With bands of only a few thousand people, these shapes are noisy, but the direction is consistent across the UN series.
Older women, fewer children
Fertility has fallen from about 6.9 children per woman in 1970 to about 2.75 in 2023, and the base has stopped widening. From age 40 women outnumber men in every band, with about 83 men per 100 women at 60–64, reflecting at least in part a large gap in life expectancy (about 64 years for men against 72 for women). The current shape is closest to Haiti, Nepal and Guatemala. The medium scenario assumes emigration continues, holding growth to about 126,000 people by 2050.
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 Micronesia’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 2087. People aged 65 and older are projected to outnumber children under 15 by 2095.
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, Micronesia is projected to record 2,509 births (about 7 births a day) and 898 deaths, a natural increase of 1,611. Net migration adds −1,121 people, ranking #228 in the net migration rate ranking.
Between 2000 and 2023 the UN estimates 67,978 births, 19,277 deaths, and cumulative net migration of −47,644. 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 −19,661 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 Micronesia are projected to live 7.7 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 115 to 18.0 deaths per 1,000 live births since 1950, ranking #67 of 237 in the infant mortality ranking (highest first). A mean age at childbearing of 28.9 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 Micronesia
The median age of 23.5 years splits the population into two equal halves. A total fertility rate of 2.67 births per woman is above the replacement level of roughly 2.1, and life expectancy at birth is 67.7 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 | 114,182 | #196 | Largest first |
| Median age | 23.5 years | #178 | Oldest first |
| Fertility rate | 2.67 | #65 | Highest first |

Largest age groups in Micronesia
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, Micronesia has 56,681 males and 57,502 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 49.6% of the population and females for 50.4%. There are 821 more females than males overall. Among people aged 65 and older, the ratio is 69.5 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, 107.0 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 Micronesia has changed since 1950
The population has increased from 32,106 in 1950 to 114,182 in 2026, a change of 256%. Over the same span, median age moved from 18.4 to 23.5 years.
The under-15 share changed from 41.2% to 31.2%, while the share aged 65 and older changed from 4.1% to 6.4%. 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, Micronesia’s population is projected to grow by about 11%, reaching 126,408 in 2050. The median age changes from 23.5 to 29.2 years.
The 65+ share is projected to rise by 1.3 percentage points to 7.7%. At the same time, the under-15 share is projected at 24.8%. How UN projections work explains the assumptions behind these figures.
The annual UN series reaches its highest projected population of 133,120 in 2075. That turning point depends on the medium scenario and may move in later revisions. Compare timing across countries in the population peak ranking.
