Population over time
In mid-1950 there were 835,000 people, so the population is now 7.9 times as large.
The UN projects 199,000 births and 41,000 deaths in 2026, 158,000 more births than deaths.
Ages
The median age is 18.7, which is 12.4 years below the world’s 31.1.
40% of the people are under 15 and 3.1% are 65 or older (world: 24% and 11%).
In the UN projection, children under 15 outnumber people aged 65 and over in every year to 2100.
Women have 4.0 children on average at today’s rates (world: 2.2), against 6.1 in 1950.
Life expectancy at birth is 66.4 years, below the world’s 73.8. In 1950 it was 39.6.
Births, deaths and the years ahead
For mid-2050 the UN projects 11 million people, 66% more than now, with a median age of 23.1.
Development and urbanisation
In 2025, 85% of the people lived in cities, 7% in towns and semi-dense areas and 8% in rural areas. For 2050 the UN projects 85% 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.

Longevity, ageing and the future
By the death rates of 2023, life expectancy at birth was 65.8 years. People who had reached 65 could expect 13.9 more years for women and 12.5 for men.
On 1 January 2026, there are 5.4 people aged 65 or more for every 100 aged 15 to 64. For 2050, the UN projects 8.8.
For 2100 the UN projects a population of 20 million, with a 95 percent prediction interval of 9.14 million to 41.6 million.
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.
