Saint Martin (French part) age distribution in 2026
Children under 15 account for 20.6% of the population, while 21.0% are aged 65 or older. The remaining 58.4% are in the conventional working-age range of 15–64. On these shares, the site classifies Saint Martin (French part)’s age structure as older; the guide to constrictive population pyramids explains what that shape implies.
The total age dependency ratio is 71.4: about 71 people under 15 or 65+ for every 100 people aged 15–64 (35.4 children and 36.0 older people). This is an age-balance indicator, not a literal count of economic dependants per worker.
What shapes Saint Martin (French part)’s population pyramid
Boom, then departure
The French part of Saint Martin, which shares a small Caribbean island with Dutch Sint Maarten and was administered as part of Guadeloupe until 2007, had about 3,000 inhabitants in 1950. A tourism and construction boom in the 1980s and 1990s drew migrants from across the Caribbean and from France, and by 2000 the population had reached about 30,000, with the widest bands at ages 30–39.
The direction then reversed. The population peaked at about 37,000 in 2014, and net migration between 2000 and 2023 was about −16,000. Hurricane Irma, which devastated the island in September 2017, coincided with further departures. The UN series puts the population at about 24,000 in 2026 and assumes continued heavy emigration, about 43 people per 1,000 residents in that year alone.
The pyramid shows who left. The 25–29 band, born about 1997–2001, is about 39% smaller than its neighbours, and from age 25 onward women clearly outnumber men, with only about 68 men per 100 women at 30–34. Above that gap, the cohorts who arrived during the boom now form the widest bands, at 55–64.
With so few people, every band is small and sensitive to a few hundred moves, and projections are especially fragile: the medium scenario carries today’s gap forward into an almost empty 50–54 band in 2050, an outcome the guide to population projections helps put in context.
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) | −39% |
| 15–19 | 2007–2011 | Bulge (larger cohort) | +20% |
| 60–64 | 1962–1966 | Bulge (larger cohort) | +13% |
Births outnumber deaths in 2026; the medium scenario projects deaths to exceed births from 2027. People aged 65 and older came to outnumber children under 15 between 2025 and 2026.
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, Saint Martin (French part) is projected to record 287 births (about 287 births a year) and 248 deaths, a natural increase of 39. Net migration adds −1,034 people, ranking #236 in the net migration rate ranking.
Between 2000 and 2023 the UN estimates 17,066 births, 3,944 deaths, and cumulative net migration of −15,943. 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 −4,582 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 Saint Martin (French part) are projected to live 6.8 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 50 to 7.5 deaths per 1,000 live births since 1950, ranking #146 of 237 in the infant mortality ranking (highest first). A mean age at childbearing of 31.1 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 Saint Martin (French part)
The median age of 43.9 years splits the population into two equal halves. A total fertility rate of 2.59 births per woman is above the replacement level of roughly 2.1, and life expectancy at birth is 80.8 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 | 23,898 | #223 | Largest first |
| Median age | 43.9 years | #31 | Oldest first |
| Fertility rate | 2.59 | #72 | Highest first |
| Annual growth | -4.2% | #237 | Fastest first |
| Life expectancy | 80.8 years | #55 | Highest first |
| Population aged 65+ | 21.0% | #40 | Highest share first |
Largest age groups in Saint Martin (French part)
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 | 60–64 | 1,951 | 8.2% | 911 / 1K |
| 2 | 55–59 | 1,854 | 7.8% | 842 / 1K |
| 3 | 15–19 | 1,849 | 7.7% | 937 / 912 |
| 4 | 10–14 | 1,805 | 7.5% | 905 / 900 |
| 5 | 50–54 | 1,668 | 7.0% | 736 / 932 |
Sex ratio and the balance by age
In the 2026 projection, Saint Martin (French part) has 11,015 males and 12,883 females. That is 85.5 males per 100 females, ranking #232 when the dataset is ordered from the highest male-to-female ratio to the lowest.
Males account for 46.1% of the population and females for 53.9%. There are 1,868 more females than males overall. Among people aged 65 and older, the ratio is 75.0 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, 104.0 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 Saint Martin (French part) has changed since 1950
The population has increased from 2,984 in 1950 to 23,898 in 2026, a change of 701%. Over the same span, median age moved from 19.8 to 43.9 years.
The under-15 share changed from 39.5% to 20.6%, while the share aged 65 and older changed from 4.4% to 21.0%. 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, Saint Martin (French part)’s population is projected to decline by about 21%, reaching 18,795 in 2050. The median age changes from 43.9 to 38.6 years.
The 65+ share is projected to rise by 11.6 percentage points to 32.6%. At the same time, the under-15 share is projected at 19.7%. How UN projections work explains the assumptions behind these figures.
The annual UN series reaches its highest estimated population of 37,450 in 2014. Historical population totals are estimates rather than exact head counts. Compare timing across countries in the population peak ranking.
