Iceland has a population of approximately 390,000 people as of 2025, making it the 175th most populous country in the world and the most sparsely populated nation in Europe. Despite ranking among the smallest national populations on Earth, Iceland is a wealthy, highly developed Nordic democracy whose people are concentrated almost entirely along the coast, leaving the volcanic interior virtually uninhabited.
How Many People Live in Iceland?
With roughly 390,000 residents, Iceland has fewer inhabitants than many individual cities. To put it in perspective, the entire country's population would comfortably fit inside a mid-sized metropolitan area such as Bologna, Italy, or Wichita in the United States. Among the world's roughly 195 sovereign states, only a few dozen micro-states and island nations have smaller populations.
Iceland's population has roughly quadrupled over the past century. In 1925 the country was home to only about 100,000 people, and as recently as the 1970s the figure stood near 220,000. Steady improvements in healthcare, living standards, and life expectancy, combined with rising immigration, have driven that long climb.

Population Density and Distribution
Iceland's population density is just about 4 people per square kilometre, among the lowest in the world and by far the lowest in Europe. This sparseness is a direct result of geography. The island spans roughly 103,000 km², but a large share is covered by glaciers, lava fields, black-sand deserts, and active volcanic zones that cannot support permanent settlement.
As a result, the population hugs the coastline. The southwestern corner around the capital is overwhelmingly dominant, while the rugged Westfjords, the central highlands, and the eastern interior remain almost empty. Travelers can drive for long stretches along the famous Ring Road without passing a single town, a reminder of just how thinly the country is peopled.
Reykjavik and the Largest Cities
The capital, Reykjavik, is home to about 140,000 people, and the Greater Reykjavik area contains roughly 230,000 residents, or close to 60% of the entire national population. Located at 64 degrees north, Reykjavik is the world's northernmost capital of a sovereign nation. The three largest urban municipalities are:
- Reykjavik — about 140,000 residents; the political, cultural, and economic heart of the country.
- Kópavogur — about 38,000 residents; a fast-growing suburb directly south of the capital.
- Hafnarfjörður — about 30,000 residents; a historic harbour town also within the capital region.
Outside the southwest, the largest settlement is Akureyri in the north, often called the "capital of the north," with around 19,000 people. No other town comes close to these figures, underscoring how centralised Iceland's population truly is.
Growth, Immigration, and Demographics
Iceland's population is currently growing at roughly 0.85% per year, a high rate by European standards. Two forces drive this. First, immigration has surged, with many newcomers arriving from Poland, Lithuania, and the Philippines to fill jobs in tourism, construction, and fisheries. Second, Iceland maintains one of the highest fertility rates in Europe, at around 1.8 children per woman.
About 85% of residents are ethnic Icelanders, descended from Norse and Celtic settlers who arrived more than a thousand years ago. The median age is roughly 37 years, and life expectancy is among the highest in the world. Icelandic, a language remarkably close to Old Norse, is the official tongue, and most Icelanders speak fluent English as well. Around 62% of the population belongs to the Lutheran National Church of Iceland, while a growing share identify as non-religious. Demographers project the population could reach about 450,000 by 2050 if current trends continue.
What Makes Iceland's Population Unique
Few populations are as distinctive as Iceland's. Because of centuries of relative isolation, most Icelanders can trace their ancestry back to the original Viking-era settlers, and a national genetic database covers nearly the entire population, making the country a global hub for genealogical and medical research. Icelanders also use a patronymic naming system rather than inherited family surnames, so a person's last name typically reflects their father's first name.
Another striking fact is the imbalance between residents and visitors. Iceland welcomes roughly 2.3 million tourists each year, outnumbering its own population by about six to one. It is also the most populous country on Earth with no standing army, navy, or air force.
Frequently Asked Questions
What is the population of Iceland in 2025?
Iceland's population is approximately 390,000 people as of 2025, ranking it 175th in the world and making it Europe's least populous and most sparsely settled nation.
What percentage of Icelanders live in Reykjavik?
Close to 60% of all Icelanders live in the Greater Reykjavik area, which has about 230,000 residents. The capital city proper is home to roughly 140,000 people.
Is Iceland's population growing or shrinking?
Iceland's population is growing, at about 0.85% per year. Growth is fueled by strong immigration and a comparatively high fertility rate of around 1.8, and the population may reach about 450,000 by 2050.
Why does Iceland have such a low population density?
At roughly 4 people per square kilometre, Iceland's density is low because glaciers, lava fields, and volcanic highlands cover much of the interior, forcing settlement into a narrow coastal band around the southwest.
