The Most Densely Populated Countries in the World

By the populationclock.org team · Published October 15, 2026 · All figures: UN World Population Prospects 2024, medium variant

The short answer

On the raw numbers the densest places are Monaco at about 25,927, Macao at about 22,508, Singapore at about 8,539 and Hong Kong at about 6,747 people per square kilometre. Every one of them is a city-state or a small territory, the largest holding about 7.4 million people, which tells you what the ranking mostly measures: whether a country is essentially a city.

Put a floor under it and the answer gets more interesting. Among the 95 countries with more than 10 million inhabitants, the densest is Bangladesh, at about 1,333 people per square kilometre, more than twice the figure for the country behind it. Then come Taiwan at about 656, Rwanda at about 589, the Netherlands at about 541, Burundi at about 541 and South Korea at about 523. Bangladesh is the one genuinely crowded large country on earth, and the gap between it and the rest is the most striking thing in the table.

How crowded is the world, actually

The dataset reports density for every country, and dividing a population by its density recovers the land area behind the figure. Summing those areas gives roughly 130 million square kilometres of inhabited land, which the 8.13 billion people of 2024 share at about 63 each per square kilometre. In 1950 the same calculation gives about 19.

The projection then does something people rarely expect. World density rises to about 74 by 2050 and only 78 by 2100. World crowding grew about 3.3 times over the past seventy-five years; over the next seventy-five it rises by about 25%. That is the shape of the rest of the century in a single indicator: not an unending squeeze, but a levelling off. The average is also a poor description of life as lived, since 154 of the 237 countries and territories sit above it, holding about 78% of the world’s people.

The last seventy-five years were universal

The striking thing about the historical record is that it has no exceptions. Every one of the 95 countries above 10 million people is denser today than in 1950. Bangladesh led that list then too, at about 317 people per square kilometre in 1950 against 1,333 now, a multiple of roughly 4.2. Behind it in 1950 came the Netherlands, Belgium and Japan, a European and East Asian list that reads nothing like the one for 2100.

That universality is what ends. On the medium projection 8 of those 95 large countries are thinner in 2100 than they were in 1950, among them Japan, Italy, Ukraine and Poland. Japan is the clearest: about 229 people per square kilometre in 1950, 328 today, and 204 in 2100, which unwinds the whole post-war increase and more.

The crowding is moving, not growing

Among countries above 10 million people, the biggest increases in people per square kilometre by 2100 are Burundi, Rwanda, Malawi, Uganda and Pakistan, and four of the five are African. Rwanda goes from about 589 people per square kilometre to 1,354, and Burundi from about 541 to 1,459, which would put both above today’s Bangladesh. Nigeria moves from about 255 to 523.

The steepest falls are Taiwan, South Korea, Japan, China and Italy, four of the five in Asia. Hong Kong is the extreme case, from about 6,747 people per square kilometre to 1,893, a little over 28% of today’s figure. China roughly halves, from about 148 to 66. India is the quiet counter-case: it adds people right through mid-century and still ends up at about 506 per square kilometre against 488 today, because its peak and its decline both fall inside the century. Nothing about the land changes in any of this. Only the number of people standing on it does.

Africa nearly catches Asia

Aggregate the same arithmetic by region and the century becomes legible. Asia is the densest region today at about 153 people per square kilometre, and in 2100 it is slightly lower, about 148. Africa goes from about 51 to 130, from roughly 33% of Asia’s density to about 88% of it. Europe moves the other way, from about 34 down to 27.

That convergence is the demographic event of the century seen through one ratio, the same thing described in the African century from the population side, and the mirror of East Asia’s decline. Among the 95 countries above 10 million people, 61 are denser in 2100 than today and 34 are thinner, which is as close to an even split as this dataset produces for anything.

Where the number misleads

Density divides people by every square kilometre a country owns, habitable or not, so a national average can describe nowhere at all. Egypt reads about 117 per square kilometre, a perfectly ordinary figure, and most Egyptians live on a small fraction of that land. Countries whose territory is largely desert, mountain or ice get the same flattening: Mongolia at about 2.2 and Australia at about 3.5 are not empty so much as concentrated somewhere the average cannot see.

Two notes on the arithmetic. The land areas here are implied by the dataset’s own density figures rather than supplied separately, and they drift by a fraction of a percent between years, so the 2024 area is held fixed throughout: otherwise that drift, rather than population, would appear to move a trend. And density inherits every uncertainty in the projection underneath it. Singapore shows how much that matters, rising from about 8,539 people per square kilometre to 8,904 by 2050 before falling to 6,095, while Bangladesh peaks around 2071 at roughly 1,649. Our methodology sets out what the low and high variants do to figures like these.

Frequently asked questions

All figures are the UN World Population Prospects 2024 medium variant. Densities are the dataset’s own; world and regional values divide population by the summed land area those densities imply. A projection is a conditional statement about what follows from a set of assumptions, not a forecast.
