Cayman Islands population pyramid 2026
Latin America and the Caribbean · Caribbean
77,196 people in 2026 (projected). The Cayman Islands grew elevenfold since 1950, largely through immigration, giving a pyramid that bulges at ages 30–59 and has a narrow base.

Cayman Islands age distribution in 2026
Children under 15 account for 15.9% of the population, while 10.1% are aged 65 or older. The remaining 74.0% are in the conventional working-age range of 15–64. On these shares, the site classifies Cayman Islands’s age structure as older; the guide to constrictive population pyramids explains what that shape implies.
The total age dependency ratio is 35.2: about 35 people under 15 or 65+ for every 100 people aged 15–64 (21.5 children and 13.6 older people). This is an age-balance indicator, not a literal count of economic dependants per worker.
What shapes Cayman Islands’s population pyramid
A pyramid made by arrivals
In 1950 the Cayman Islands had about 7,000 inhabitants. By 2026 the figure is about 77,000, and most of the growth has come from immigration linked to the territory’s development as an offshore financial centre and tourist destination. The UN estimates net immigration of about 21,000 people between 1950 and 1999 and 24,000 between 2000 and 2023; in 2026 net migration is still roughly twice the natural increase.
Because migrants arrive mostly as working adults, the pyramid bulges in the middle. In 2000 the bands at 25–39 were about twice as wide as the 15–19 band, and in 2026 the widest bands are 35–49. Fertility, about 1.5 children per woman, has been below replacement since around 1990, so the base is narrow.
Balanced sexes, sensitive bands
Unlike some migration-driven populations, the Cayman Islands have close to equal numbers of men and women, about 101 men per 100 women. With fewer than 100,000 people, though, five-year bands hold only a few thousand people each, so small shifts in migration produce visible bumps that would be invisible in a larger country.
The structure is closest to those of the Turks and Caicos Islands, the British Virgin Islands and Luxembourg. Under the UN medium scenario, which assumes continued immigration, the population passes 100,000 by 2050, when today’s large middle-aged cohorts have moved up to form the widest bands, at 55–69.
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 Cayman Islands’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 2054. People aged 65 and older are projected to outnumber children under 15 by 2035.
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, Cayman Islands is projected to record 843 births (about 2 births a day) and 386 deaths, a natural increase of 457. Net migration adds +888 people, ranking #8 in the net migration rate ranking.
Between 2000 and 2023 the UN estimates 17,607 births, 6,807 deaths, and cumulative net migration of +24,006. 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 +21,092 between 2026 and 2050.

Women in Cayman Islands are projected to live 4.7 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 79 to 1.1 deaths per 1,000 live births since 1950, ranking #235 of 237 in the infant mortality ranking (highest first). A mean age at childbearing of 31.0 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 Cayman Islands
The median age of 39.1 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 80.9 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 | 77,196 | #205 | Largest first |
| Median age | 39.1 years | #69 | Oldest first |
| Fertility rate | 1.50 | #167 | Highest first |
| Annual growth | +1.7% | #56 | Fastest first |
| Life expectancy | 80.9 years | #54 | Highest first |
| Population aged 65+ | 10.1% | #118 | Highest share first |
Largest age groups in Cayman Islands
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 |
|---|---|---|---|---|

| 2 | 35–39 | 7,034 | 9.1% | 3.6K / 3.5K |
| 3 | 45–49 | 6,869 | 8.9% | 3.5K / 3.4K |

| 5 | 30–34 | 6,196 | 8.0% | 3.1K / 3.1K |
Sex ratio and the balance by age
In the 2026 projection, Cayman Islands has 38,734 males and 38,462 females. That is 100.7 males per 100 females, ranking #67 when the dataset is ordered from the highest male-to-female ratio to the lowest.
Males account for 50.2% of the population and females for 49.8%. There are 272 more males than females overall. Among people aged 65 and older, the ratio is 85.8 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, 103.6 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 Cayman Islands has changed since 1950
The population has increased from 7,002 in 1950 to 77,196 in 2026, a change of 1002%. Over the same span, median age moved from 23.5 to 39.1 years.
The under-15 share changed from 32.6% to 15.9%, while the share aged 65 and older changed from 6.5% to 10.1%. 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, Cayman Islands’s population is projected to grow by about 35%, reaching 103,958 in 2050. The median age changes from 39.1 to 44.3 years.
The 65+ share is projected to rise by 15.2 percentage points to 25.3%. At the same time, the under-15 share is projected at 13.7%. How UN projections work explains the assumptions behind these figures.
The annual UN series reaches its highest projected population of 118,127 in 2097. That turning point depends on the medium scenario and may move in later revisions. Compare timing across countries in the population peak ranking.
