Saint Barthélemy age distribution in 2026
Children under 15 account for 17.4% of the population, while 18.6% are aged 65 or older. The remaining 64.0% are in the conventional working-age range of 15–64. On these shares, the site classifies Saint Barthélemy’s age structure as older; the guide to constrictive population pyramids explains what that shape implies.
The total age dependency ratio is 56.4: about 56 people under 15 or 65+ for every 100 people aged 15–64 (27.3 children and 29.1 older people). This is an age-balance indicator, not a literal count of economic dependants per worker.
What shapes Saint Barthélemy’s population pyramid
A tiny island shaped by newcomers
With about 11,500 residents, Saint Barthélemy has a pyramid in which each five-year band holds only a few hundred people. A handful of births, deaths or moves can therefore change a band noticeably, and some features of the UN series, such as the jagged older bands of 1975, are better read as small-number noise than as history.
The broad trend is clear, though. The population rose from about 2,000 in 1950 to 7,100 in 2000 and 11,500 in 2026, mostly through migration, widely associated with the growth of high-end tourism: the UN estimates net gains of about 3,200 people over 1950–99 and 3,500 over 2000–23. In 2000 men outnumbered women at most working ages, with about 123 men per 100 women at 30–34. By 2026 the balance has reversed among adults, with women in the majority in every band from 25 upward and only 79 men per 100 women at 40–44; the chart alone cannot say what changed in the composition of migrants.
Fewer than five hundred under-fives
Fertility fell below two children per woman by 1980 and to about 0.8 in 2023, far below the replacement level. The base of the 2026 pyramid is correspondingly narrow: about 450 children under five, against roughly 770 aged 5–9. Deaths first outnumbered births in 2020, and continued immigration is what keeps the population growing towards a projected peak of about 12,800 in 2047. Its age structure is closest to those of Réunion, the Faroe Islands and Montenegro.
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 |
|---|---|---|---|
| 20–24 | 2002–2006 | Bulge (larger cohort) | +12% |
Deaths have exceeded births every year since 2020. 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 Barthélemy is projected to record 62 births (about 62 births a year) and 77 deaths, a natural decrease of 15. Net migration adds +143 people, ranking #5 in the net migration rate ranking.
Between 2000 and 2023 the UN estimates 1,793 births, 1,074 deaths, and cumulative net migration of +3,470. 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 +1,762 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 Barthélemy are projected to live 5.3 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 101 to 4.9 deaths per 1,000 live births since 1950, ranking #169 of 237 in the infant mortality ranking (highest first). A mean age at childbearing of 30.9 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 Saint Barthélemy
The median age of 39.1 years splits the population into two equal halves. A total fertility rate of 0.84 births per woman is below the replacement level of roughly 2.1, and life expectancy at birth is 84.6 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 | 11,550 | #228 | Largest first |
| Median age | 39.1 years | #69 | Oldest first |
| Fertility rate | 0.84 | #234 | Highest first |
| Annual growth | +1.1% | #96 | Fastest first |
| Life expectancy | 84.6 years | #5 | Highest first |
| Population aged 65+ | 18.6% | #56 | Highest share first |
Largest age groups in Saint Barthélemy
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 | 20–24 | 864 | 7.5% | 438 / 426 |
| 2 | 15–19 | 856 | 7.4% | 434 / 422 |
| 3 | 55–59 | 798 | 6.9% | 365 / 433 |
| 4 | 10–14 | 792 | 6.9% | 398 / 394 |
| 5 | 60–64 | 787 | 6.8% | 363 / 424 |
Sex ratio and the balance by age
In the 2026 projection, Saint Barthélemy has 5,423 males and 6,126 females. That is 88.5 males per 100 females, ranking #225 when the dataset is ordered from the highest male-to-female ratio to the lowest.
Males account for 47.0% of the population and females for 53.0%. There are 703 more females than males overall. Among people aged 65 and older, the ratio is 77.9 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, 104.0 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 Barthélemy has changed since 1950
The population has increased from 2,006 in 1950 to 11,550 in 2026, a change of 476%. Over the same span, median age moved from 26.8 to 39.1 years.
The under-15 share changed from 28.9% to 17.4%, while the share aged 65 and older changed from 7.2% to 18.6%. 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 Barthélemy’s population is projected to grow by about 11%, reaching 12,789 in 2050. The median age changes from 39.1 to 44.5 years.
The 65+ share is projected to rise by 7.5 percentage points to 26.1%. At the same time, the under-15 share is projected at 11.9%. How UN projections work explains the assumptions behind these figures.
The annual UN series reaches its highest projected population of 12,818 in 2047. That turning point depends on the medium scenario and may move in later revisions. Compare timing across countries in the population peak ranking.
