Saint Lucia population pyramid 2026
Latin America and the Caribbean · Caribbean
180,488 people in 2026 (projected). Saint Lucia’s pyramid now narrows at the base: fertility fell from about 6.8 to 1.4 children per woman in six decades, and the widest bands are adults aged 25–34.

Saint Lucia age distribution in 2026
Children under 15 account for 17.1% of the population, while 10.3% are aged 65 or older. The remaining 72.6% are in the conventional working-age range of 15–64. On these shares, the site classifies Saint Lucia’s age structure as older; the guide to constrictive population pyramids explains what that shape implies.
The total age dependency ratio is 37.8: about 38 people under 15 or 65+ for every 100 people aged 15–64 (23.5 children and 14.2 older people). This is an age-balance indicator, not a literal count of economic dependants per worker.
What shapes Saint Lucia’s population pyramid
An island of emigrants
Between 1950 and 1999 about 88,000 more people left Saint Lucia than arrived, almost as many as the island’s entire 1950 population of 93,000. Like others across the Eastern Caribbean, Saint Lucians moved in large numbers to Britain and later to North America. Emigration took mostly young adults, and the 1975 pyramid shows it clearly: above a broad base of children, the bands from 20 to 39 are strikingly thin, with more women than men left at those ages.
From six children to fewer than one and a half
Fertility then fell steeply, from about 6.8 children per woman in 1960 to 2.2 by 2000 and about 1.4 today, well below replacement level. The cohorts born in the early 1990s, now 30–34, form the widest band, and each younger band is smaller. Deaths first outnumbered births in 2021, and the population is close to its projected peak of about 181,500 in 2032.
Women live about seven years longer than men, so the top of the pyramid leans female, with 60 men per 100 women at 80–84. With only about 180,000 residents, the bands under 65 hold about 10,000–16,000 people each, so small irregularities should not be over-read. Under the medium scenario the population falls to about 108,000 by 2100, when a third of residents are 65 or older. Jamaica and the Bahamas have similar age structures.
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 Lucia’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 2033. 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 Lucia is projected to record 1,959 births (about 5 births a day) and 1,611 deaths, a natural increase of 348. Net migration adds −49 people, ranking #120 in the net migration rate ranking.
Between 2000 and 2023 the UN estimates 56,399 births, 30,327 deaths, and cumulative net migration of −4,273. 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 −1,204 between 2026 and 2050.

Women in Saint Lucia are projected to live 7.0 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 118 to 13.0 deaths per 1,000 live births since 1950, ranking #89 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 Saint Lucia
The median age of 35.1 years splits the population into two equal halves. A total fertility rate of 1.37 births per woman is below the replacement level of roughly 2.1, and life expectancy at birth is 73.2 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 | 180,488 | #191 | Largest first |

Largest age groups in Saint Lucia
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, Saint Lucia has 88,939 males and 91,548 females. That is 97.1 males per 100 females, ranking #149 when the dataset is ordered from the highest male-to-female ratio to the lowest.
Males account for 49.3% of the population and females for 50.7%. There are 2,609 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, 103.1 boys are projected to be born for every 100 girls in 2026, slightly below the typical value 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 Lucia has changed since 1950
The population has increased from 92,991 in 1950 to 180,488 in 2026, a change of 94%. Over the same span, median age moved from 16.3 to 35.1 years.
The under-15 share changed from 46.1% to 17.1%, while the share aged 65 and older changed from 3.3% to 10.3%. 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 Lucia’s population is projected to decline by about 5%, reaching 172,080 in 2050. The median age changes from 35.1 to 45.7 years.
The 65+ share is projected to rise by 10.1 percentage points to 20.4%. At the same time, the under-15 share is projected at 13.0%. How UN projections work explains the assumptions behind these figures.
The annual UN series reaches its highest projected population of 181,492 in 2032. That turning point depends on the medium scenario and may move in later revisions. Compare timing across countries in the population peak ranking.
