Cambodia in numbers

17,423,880 people lived in Cambodia in mid-2023: 0.22% of the world's people, and the 73rd-largest population of the 236 countries and areas the UN reports. That is 4.0 times its 1950 population of 4.4 million.

The UN's medium projection has it peaking in 2078 at 23.4 million, then falling to 22.7 million by 2100. The projection is uncertain: on 1 January 2100 the UN's 95% range runs from 8.5 million to 56.1 million.

The medium projection has deaths passing births in 2088 and staying above them from then on. Deaths also outnumbered births in 1975–1978.

The median age was 18.5 in 1950 and 26.8 in 2023; the projection has 43.7 in 2100. 6.0% of people were 65 or older in 2023, against 23.5% projected for 2100. The working-age population (15–64) is projected to peak in 2069 at 15.1 million.

By size it is the 73rd country in 2023; the projection puts it 73rd in 2050 and 71st in 2100. In the medium projection it overtakes Romania in 2029, the Netherlands in 2030 and Ecuador in 2038. It is overtaken by Zimbabwe in 2032, Benin in 2041 and Burundi in 2042.

Cambodia, every age in every year

Each column is a year and each row an age; the denser the ink in a cell, the more people. Everyone born in the same year climbs one 45° diagonal, so famines, baby booms and migration show up as streaks. Select a cell to follow its generation.

KHM · ages 15–64

Who does the work in Cambodia

On the UN's projection, Cambodia will have the most working-age people it ever has in 2069: 15,052,700 people aged 15–64. In 2023 it had 11,138,800.

100 aged 15–64

How to read this: the orange squares are 100 people aged 15–64 in 2023, and the rows below are how many children (teal) and how many people aged 65 or older (violet) lived alongside them.

Fewer than 50 dependants live alongside every 100 people aged 15–64 in 4 years: 2041–2044.

fewer than 50 dependants per 100   the same, projected   50 or more

How to read this: one stripe a year from 1950 to 2100. A stripe takes colour in a year when fewer than 50 dependants live alongside every 100 people of working age, and stays grey otherwise; hatching means the year is projected.

How every country compares

KHM · arrivals minus departures

Who arrives in Cambodia, and who leaves

In 2020–2025 Cambodia loses 27,782 people a year: everyone who arrives, minus everyone who leaves. The age at which that happens most is 20–24, at 9,431 a year more leaving than arriving.

one square = 1,000 people a year
020406080+

more arrive than leave   more leave than arrive

How to read this: left to right is age, from babies to 100. Blue squares above the line are ages at which more people arrive than leave; orange squares below it, ages at which more leave than arrive. These are the UN's projection for 2020–2025. There is no record of migration by age before 2020.

Across the counted years, 1950 to 2023, its biggest single-year gain was 508,187 (1996); its biggest loss, 193,008 (1970).

In 2024, 83,925 people living in Cambodia had been born in another country, fewer than 1 of every 100 people there, against fewer than 1 in 1990.

Years in good health in Cambodia

Of the 68.9 years a baby born in Cambodia in 2021 could expect, about 60.6 would be lived in full health (95% range 59.8–61.6). That leaves 8.3 years in less than full health, fewer than the world's 9.5, which mostly means lives are shorter here, with fewer years in which to be ill.

How to read this: each square is a year of life, each row ten years; filled squares are years in full health, rounded to whole years.

Women: 62.0 healthy years of 71.5. Men: 59.3 of 66.4. In 2019, before the pandemic, the healthy years were 61.3.

Displacement in Cambodia

At the end of 2025, 517,555 people were displaced inside Cambodia, about 29 of every 1,000 people living there.

How to read this: one square stands for 10,000 people, so the rows can be compared with one another. The last row is people from Cambodia living in another country, wherever they are. An outlined square means fewer people than one square stands for.

In 2025, 850 people from Cambodia asked for asylum in another country. Of every 100 people from Cambodia whose claims were decided that year, 12 were given protection. Who asks for asylum, and who is given it

The young went further: 12.7 of every 100 women aged 25–29 never went to school, against 37.4 of every 100 aged 60–64 (men: 10.6 against 19.7).

The middle projection has its working-age people most numerous in 2050; those among them who finished upper secondary are most numerous later, in 2090.
