Saint Kitts and Nevis age distribution in 2026
Children under 15 account for 18.4% of the population, while 12.2% are aged 65 or older. The remaining 69.4% are in the conventional working-age range of 15–64. On these shares, the site classifies Saint Kitts and Nevis’s age structure as older; the guide to constrictive population pyramids explains what that shape implies.
The total age dependency ratio is 44.0: about 44 people under 15 or 65+ for every 100 people aged 15–64 (26.5 children and 17.5 older people). This is an age-balance indicator, not a literal count of economic dependants per worker.
What shapes Saint Kitts and Nevis’s population pyramid
A population held in check by emigration
The federation had about 47,000 people in 1950 and about the same number in 2026; it peaked at roughly 56,000 in 1960. The flat total hides heavy movement. The UN estimates a net outflow of about 46,000 people between 1950 and 1999, close to the entire population, as Kittitians and Nevisians left for the United Kingdom, the United States, the US Virgin Islands and other parts of the Caribbean.
The pyramids record those departures. In 1950 women outnumbered men at almost every age, a sign that men had already been leaving to work elsewhere. By 1975 young adults were missing on a large scale: high fertility had produced a broad base, but the 35–39 band held less than a fifth as many people as 10–14, and the bands at 55–64 were larger than those at 30–44. Because each band contains only a few thousand people, such gaps are easy to see but also sensitive to errors in the estimates, as the guide to reading pyramids notes.
Lower fertility, fewer men
Fertility fell from about 6.5 children per woman in 1960 to 1.5 today, and emigration has slowed to almost nothing. The widest bands in 2026 are 35–44, and women outnumber men from age 10 upward, giving an overall ratio of about 91 men per 100 women. Deaths first exceeded births in 2021, and under the UN medium scenario the population declines slowly to about 44,000 in 2050. The structure is close to those of Antigua and Barbuda and other Eastern Caribbean states.
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 Saint Kitts and Nevis’s 2026 pyramid has a comparatively smooth profile without sharp bulges or notches.
Births outnumber deaths in 2026 (deaths were higher in 2021); the medium scenario projects deaths to exceed births from 2030. People aged 65 and older are projected to outnumber children under 15 by 2040.
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 Kitts and Nevis is projected to record 528 births (about 1 births a day) and 473 deaths, a natural increase of 55. Net migration adds +11 people, ranking #89 in the net migration rate ranking.
Between 2000 and 2023 the UN estimates 16,409 births, 10,662 deaths, and cumulative net migration of −3,861. 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 −338 between 2026 and 2050.

Women in Saint Kitts and Nevis are projected to live 7.4 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 94 to 11.5 deaths per 1,000 live births since 1950, ranking #98 of 237 in the infant mortality ranking (highest first). A mean age at childbearing of 27.6 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 Kitts and Nevis
The median age of 36.5 years splits the population into two equal halves. A total fertility rate of 1.50 births per woman is below the replacement level of roughly 2.1, and life expectancy at birth is 72.6 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 | 46,992 | #212 | Largest first |
| Median age | 36.5 years | #99 | Oldest first |
| Fertility rate | 1.50 | #167 | Highest first |
| Annual growth | +0.1% | #166 | Fastest first |
| Life expectancy | 72.6 years | #154 | Highest first |
| Population aged 65+ | 12.2% | #105 | Highest share first |
Largest age groups in Saint Kitts and Nevis
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.

| 5 | 45–49 | 3,323 | 7.1% | 1.6K / 1.8K |
Sex ratio and the balance by age
In the 2026 projection, Saint Kitts and Nevis has 22,440 males and 24,552 females. That is 91.4 males per 100 females, ranking #206 when the dataset is ordered from the highest male-to-female ratio to the lowest.
Males account for 47.8% of the population and females for 52.2%. There are 2,112 more females than males overall. Among people aged 65 and older, the ratio is 77.8 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, 103.7 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 Kitts and Nevis has changed since 1950
The population has decreased from 47,232 in 1950 to 46,992 in 2026, a change of 1%. Over the same span, median age moved from 21.2 to 36.5 years.
The under-15 share changed from 39.7% to 18.4%, while the share aged 65 and older changed from 5.4% to 12.2%. 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 Kitts and Nevis’s population is projected to decline by about 6%, reaching 44,249 in 2050. The median age changes from 36.5 to 43.9 years.
The 65+ share is projected to rise by 8.4 percentage points to 20.6%. At the same time, the under-15 share is projected at 14.3%. How UN projections work explains the assumptions behind these figures.
The annual UN series reaches its highest estimated population of 55,810 in 1960. Historical population totals are estimates rather than exact head counts. Compare timing across countries in the population peak ranking.
