San Marino population pyramid 2026
33,605 people in 2026 (projected). San Marino’s pyramid is top-heavy: people aged 55–59 outnumber children under five almost three to one, as fertility stays near 1.2 children per woman.

San Marino age distribution in 2026
Children under 15 account for 11.4% of the population, while 23.8% are aged 65 or older. The remaining 64.7% are in the conventional working-age range of 15–64. On these shares, the site classifies San Marino’s age structure as older; the guide to constrictive population pyramids explains what that shape implies.
The total age dependency ratio is 54.5: about 55 people under 15 or 65+ for every 100 people aged 15–64 (17.7 children and 36.8 older people). This is an age-balance indicator, not a literal count of economic dependants per worker.
What shapes San Marino’s population pyramid
Long lives, few births
San Marino, an enclave of about 34,000 people within Italy, combines two extremes. Fertility has been at or below about 1.5 children per woman since 1980 and is now about 1.2, among the lowest anywhere, while life expectancy, about 86 years in 2023, is among the highest. The result is a pyramid that is widest in the late fifties and early sixties: the cohorts born in the 1960s, the widest part of the 2000 pyramid at 30–39, are now 55–64, and they outnumber children under five almost three to one.
Held steady by migration
Deaths have exceeded births since 2015, yet the population has barely changed, because people moving in, many of them from Italy, have offset the deficit. Over 2000–23 as a whole, net immigration of about 6,400 was more than ten times the natural increase of about 600. With only about 1,000–1,600 people in each of the youngest bands, these flows and random variation easily move individual bands; the 119 men per 100 women at 20–24 is the kind of irregularity that small numbers and migration can produce.
Under the medium scenario the population stays close to 31,000–34,000 for the rest of the century, while the bulge moves to the top: in 2050 the widest bands are at 75–84, and 37% of residents are 65 or older. Its structure is closest to Italy’s, Greece’s and Spain’s.
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 San Marino’s 2026 pyramid has a comparatively smooth profile without sharp bulges or notches.
Deaths have exceeded births every year since 2015. People aged 65 and older came to outnumber children under 15 between 1995 and 2000.
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, San Marino is projected to record 195 births (about 195 births a year) and 291 deaths, a natural decrease of 96. Net migration adds +127 people, ranking #33 in the net migration rate ranking.
Between 2000 and 2023 the UN estimates 6,532 births, 5,961 deaths, and cumulative net migration of +6,402. 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 +3,494 between 2026 and 2050.

Women in San Marino are projected to live 2.9 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 21 to 1.0 deaths per 1,000 live births since 1950, ranking #237 of 237 in the infant mortality ranking (highest first). A mean age at childbearing of 32.8 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 San Marino
The median age of 49.1 years splits the population into two equal halves. A total fertility rate of 1.17 births per woman is below the replacement level of roughly 2.1, and life expectancy at birth is 86.0 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 | 33,605 | #221 | Largest first |
| Median age | 49.1 years | #6 | Oldest first |
| Fertility rate | 1.17 | #222 | Highest first |
| Annual growth | +0.1% | #170 | Fastest first |
| Life expectancy | 86.0 years | #2 | Highest first |
| Population aged 65+ | 23.8% | #16 | Highest share first |
Largest age groups in San Marino
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, San Marino has 16,526 males and 17,080 females. That is 96.8 males per 100 females, ranking #155 when the dataset is ordered from the highest male-to-female ratio to the lowest.
Males account for 49.2% of the population and females for 50.8%. There are 554 more females than males overall. Among people aged 65 and older, the ratio is 88.0 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, 106.5 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 San Marino has changed since 1950
The population has increased from 12,948 in 1950 to 33,605 in 2026, a change of 160%. Over the same span, median age moved from 30.4 to 49.1 years.
The under-15 share changed from 25.3% to 11.4%, while the share aged 65 and older changed from 10.1% to 23.8%. 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, San Marino’s population is projected to remain broadly stable, reaching 33,696 in 2050. The median age changes from 49.1 to 50.8 years.
The 65+ share is projected to rise by 13.0 percentage points to 36.8%. At the same time, the under-15 share is projected at 11.7%. How UN projections work explains the assumptions behind these figures.
