Population over time
In mid-1950 there were 57,100 people, so the population is now 1.8 times as large.
Ages
The median age is 43.9, which is 12.8 years above the world’s 31.1.
14% of the people are under 15 and 19% are 65 or older (world: 24% and 11%).
People aged 65 and over have outnumbered children under 15 since 2014.
Women have 1.4 children on average at today’s rates (world: 2.2), against 2.2 in 1950.
Life expectancy at birth is 80.1 years, above the world’s 73.8. In 1950 it was 69.4.
Births, deaths and the years ahead
For mid-2050 the UN projects 105,000 people, 0.6% more than now, with a median age of 46.2.
Development and urbanisation
In 2025, 51% of the people lived in cities, 40% in towns and semi-dense areas and 9% in rural areas. For 2050 the UN projects 51% in cities.
Degree of urbanisation: one rule for every country, a city has at least 50,000 people at 1,500 or more per km². National definitions of “urban” differ.
Each value is the latest one published, with the year it refers to. Countries publish in different years. Sources: World Bank, World Development Indicators (ITU, SDG 7.1.1, UNESCO UIS), UNDP, Human Development Report, UN, World Urbanization Prospects 2025.
Longevity, ageing and the future
By the death rates of 2023, life expectancy at birth was 79.7 years. People who had reached 65 could expect 20.0 more years for women and 16.8 for men.
On 1 January 2026, there are 29.4 people aged 65 or more for every 100 aged 15 to 64. For 2050, the UN projects 49.8.
For 2100 the UN projects a population of 99,800, with a 95 percent prediction interval of 29,100 to 198,000.
Life expectancy at birth is a period measure. It sums up the death rates of one year and is not a forecast of how long the babies born that year will live.

Rows from 2024 on are UN projections (medium variant), shown in italics.
The UN estimates every country and area within its present borders for every year since 1950, also for years before it became independent or took its present shape. Figures for earlier years therefore describe the people who lived on today’s territory.
