Population density measures how many people live in a given area, typically expressed as inhabitants per square kilometer. The world's most densely populated places are almost all small territories — city-states, special administrative regions, and small island nations — where limited land area combines with large populations, creating extreme concentrations of people. This list ranks the top ten countries and territories by population density using the latest UN World Population Prospects and World Bank estimates. The ranking includes both sovereign states and self-governing territories, reflecting the most commonly cited global density comparison.
Macau, a Special Administrative Region of China, is the world's most densely populated territory with approximately 21,981 people per square kilometer. The former Portuguese colony spans just 33 km² on the Pearl River Delta, yet houses over 723,000 people. Its economy is driven by casinos and tourism — Macau is the world's largest gambling hub, generating more gaming revenue than Las Vegas.
Monaco, the world's second-smallest sovereign state (just 2 km²), has a population density of 19,044 people per km². The city-state on the French Riviera is known for its luxury casinos, Grand Prix, and as a tax haven for the wealthy. With only 38,000 residents but extreme land scarcity, it packs one of the highest concentrations of wealth anywhere on Earth.
Singapore, a sovereign city-state in Southeast Asia, has a population density of 8,225 people per km². Despite being one of the world's most densely populated countries, Singapore is a global financial hub with a highly developed economy, world-class infrastructure, and one of the highest GDP-per-capita figures in the world. Its 5.9 million residents occupy just 710 km².
Hong Kong, another Special Administrative Region of China, has a density of 7,027 people per km² across its 1,100 km² territory. The former British colony is one of the world's leading financial centers, with 7.4 million residents concentrated in a small area — most of Hong Kong's territory is mountainous and undeveloped, forcing extreme density in the urban areas.
Bahrain, an island nation in the Persian Gulf, has a population density of 2,134 people per km². The smallest sovereign state in the Middle East, Bahrain has grown rapidly as a financial and banking hub, with its population surging past 1.6 million — including over 1 million foreign workers who make up most of the labor force.
The Maldives, an archipelago nation of 1,192 coral islands in the Indian Ocean, has a population density of 1,772 people per km². With an average elevation of just 1.5 meters above sea level, it is the world's lowest-lying country. Its 531,000 residents are spread across only 300 km² of land, though the total territory spans 90,000 km² of ocean.
Malta, a small island nation in the Mediterranean Sea, has a population density of 1,716 people per km². The archipelago of just 316 km² is home to 549,000 people, making it the most densely populated country in the European Union. Malta's economy is driven by tourism, financial services, and online gaming.
Bangladesh is the most densely populated large country in the world, with 1,366 people per km² across 147,600 km² — a land area roughly the size of Iowa. Its 177 million people make it the eighth-most populous country globally, and its density is unmatched among nations with populations over 10 million. The capital, Dhaka, is one of the most crowded cities on Earth.
Vatican City, the world's smallest independent state at just 0.44 km², has a population density of approximately 1,150 people per km². The Holy See's 506 residents include the Pope, cardinals, diplomats, and Swiss Guard members. While its density is high, it is in a unique category — the Vatican is a city-state with virtually no permanent residential population in the traditional sense.
The Netherlands is the most densely populated large country in Western Europe, with 548 people per km² across 41,900 km². Despite its high density, the Netherlands is one of the world's largest agricultural exporters, thanks to advanced farming techniques. The country's famous land-reclamation and water-management systems have allowed it to support 18.4 million people efficiently.

Countries and territories are ranked by population density (people per square kilometer of land area), calculated using 2024–2026 UN World Population Prospects estimates for population and CIA World Factbook / UN data for land area. The data is sourced from World Population Review's 2026 density rankings, which compiles the most recent available figures. Microstates and territories with very small land areas dominate the top of the ranking, as dividing a moderate population by a tiny area produces extreme density values.
Population density divides a population by land area. Very small territories like Macau, Monaco, and Hong Kong have tiny land areas but significant populations, which produces extreme density figures. Large countries with big populations, like Bangladesh, have more moderate densities because they also have substantial land area.
It's calculated by dividing a country's total population by its land area (in square kilometers). This does not include water area. The UN and World Bank use different population estimates, so figures may vary slightly between sources.
No. Population density measures people per unit of land area across an entire country. A country can have high density but be largely rural (like Bangladesh), or have moderate density with high urbanization (like Canada). They are related but different concepts.
