Countries by Population Density 2025

What are the most densely populated countries in the world? Perhaps surprisingly, the most populous countries in the world, China and India, are far from the most densely populated.

The fact is, China and India are simply too large to have the highest population density. In the same way that a stadium holds far more people in total but a bus is easier to fill to capacity, several tiny countries and territories fit far more people into each square kilometer than even the most populous large countries.

For example, the most densely populated country in the world in 2020 was the diminutive European city-state of Monaco. Located near the French Riviera on the northern edge of the Mediterranean Sea, Monaco has a population of fewer than 40,000 people compared to China’s 1.4 billion—but squeezes them into a mere two km² of land area (compared to China’s 9.7 million km²).

Top 10 Most Densely Populated Countries in the World

It is notable that most of these locations are quite small or tiny. The top five together have a total area of less than 2,000 km². Moreover, most are also highly urbanized centers of wealth and finance, with a tendency toward cities and skyscrapers rather than rolling fields or vast wilderness areas.

Top 10 Least Densely Populated Countries in the World

On the other end of the spectrum, some of the largest countries in the world by land area have quite low population densities. For example, Russia has a population density of just 9/km², while Canada is even lower at 4/km². The United States of America has a population density of 38/km², which is quite low considering the U.S. is also the country with the third-highest population in the world. For comparison, the two countries with the highest populations—China and India—have population densities of 151/km² and 488/km², respectively.
