Compare Cambodia with another country
Where it stands
In 2025 Cambodia has 17,847,982 people, which is 0.22% of the 8.19 billion counted across the 217 countries and areas on this site. That puts it 72nd by population, behind Netherlands and ahead of Zimbabwe.
Since 1960
In 1960 the figure was 5,449,966. Since then the population has grown 3.27×, an average of 1.84% a year upward. It doubled at some point along the way — the year it first reached 10,899,932 was 1997.
The projection keeps rising to the end of the data: 21,931,455 in 2050, 22.9% above 2025. The highest figure on this page is that last one, so no peak has been reached yet.
The ranking in 2050
In 2050 the projected rank is 73rd, down 1 place from 72nd. Rankings move when other countries grow faster or slower, not only when Cambodia changes.
People and land
Cambodia covers 176,520 km² of land, so 2025 density is 101 people per km² — 105th most crowded of 216 places with an area figure. At that density a square 10 km on a side holds about 10,111 people.
The fertility rate was 2.55 births per woman in 2024, above replacement level but falling in most countries; life expectancy at birth was 70.8 years (2024); 29.5% of people were under 15 and 6.4% were 65 or older (2025); 41% of the population lived in cities. These shape the curve above: a young population keeps growing after fertility falls, an old one starts shrinking sooner.
Its nearest neighbours in the ranking are Netherlands just above, with 18.1 million (1.01× as many), and Zimbabwe just below, with 17 million (1.05× as many as Zimbabwe has).
