Iceland Statistics: The Country by the Numbers

Iceland's population reached 394,324 on 1 January 2026, up 4,880 (1.3%) during 2025 — continuing a growth run driven mainly by immigration. Immigrants (foreign-born residents) made up 19.6% of the population at the start of 2026, with people born in Poland the largest group at roughly 30% of all immigrants. The population passed 395,000 during the first quarter of 2026 (all figures: Statistics Iceland). For the story behind the numbers — the naming system, the genealogy database, where people live — see our full Iceland population guide.

Is Iceland densely populated?

No — the opposite. At roughly 3.9 people per km² (394,324 people across about 103,000 km²), Iceland is among the least densely populated countries in Europe. For comparison, the United Kingdom has about 281 people per km² and Norway about 15. Most of the interior highlands are uninhabited; nearly two thirds of all Icelanders live in and around the capital region.

Iceland is a small, open, high-income economy. GDP was US$33.2 billion in 2024 (World Bank), with preliminary 2025 figures around US$38.6 billion. After a mild contraction of 1.3% in 2024, the economy returned to 1.3% real growth in 2025 (Statistics Iceland). Inflation remained elevated at 5.2% year-on-year in June 2026, and seasonally adjusted unemployment stood at 5.6% in May 2026 — noticeably higher than a year earlier.

What is Iceland's main industry?

Three pillars carry the export economy: tourism (8.1% of GDP in 2024 and roughly one in ten hours worked), fisheries (marine products were 38.9% of goods export value in 2025), and energy-intensive industry — chiefly aluminium smelting (34.5% of goods export value), powered by cheap renewable electricity. Finance, tech, and creative industries round out a diversified services economy centered on the capital region.

Tourism is where Iceland's numbers get striking: about 2.25 million foreign visitors passed through Keflavík Airport in 2025 — roughly 5.7 for every resident. Few countries host so many guests relative to their own population. Most arrivals concentrate on the capital, the Golden Circle, the south coast, and the Blue Lagoon.

Iceland sits at or near the top of nearly every global quality-of-life index. It leads the UN Human Development Index (score 0.972, 2025 report), has closed more of its gender gap than any other country for 16 straight years (World Economic Forum, 2025), and ranked second in the 2026 World Happiness Report. Education spending, at 5.6% of GDP, runs well above the OECD average, and 44% of 25–64-year-olds hold a tertiary degree (OECD).

Crime and safety

Iceland has topped the Global Peace Index every year since 2008. Homicide is rare enough that single cases move the national rate: it has ranged between roughly 0.3 and 1.3 per 100,000 people in recent years (UNODC data via the World Bank), which typically means zero to five cases a year. Regular police officers patrol unarmed, carrying only batons and pepper spray. For travelers, the practical risks are weather, road conditions, and terrain — not crime; check SafeTravel and the weather guides before heading out.

Religion in numbers

The Evangelical Lutheran Church of Iceland remains the national church, with 56.3% of the population registered as members at the start of 2026 — down from 92.6% in 1990. The fastest-changing lines in the registry are the non-religious and smaller communities: the secular Humanist association (Siðmennt) and the Ásatrú association (reviving the old Norse religion) each count about 1.6% of the population, and 7.7% are registered outside any religious or life-stance organization.

How many volcanoes are in Iceland?

Iceland has 32 active volcanic systems according to the official Catalogue of Icelandic Volcanoes, and erupts on average every three to six years. The recent record has been busier than average: after Eyjafjallajökull's ash cloud grounded European aviation in 2010, the Reykjanes Peninsula reawakened in 2021 — three Fagradalsfjall eruptions (2021–2023) were followed by nine eruptions on the Sundhnúkur crater row near Grindavík between December 2023 and August 2025. The most recent eruption ended on 5 August 2025, and the Icelandic Met Office reports continued magma accumulation beneath Svartsengi as of mid-2026. See the full volcanic eruptions guide and our volcano guides for current status and visiting information.

Climate at a glance

Despite the name and the latitude (63–66°N), coastal Iceland is temperate: the Gulf Stream keeps Reykjavík's January average near 0°C — milder than New York's — while July peaks at a cool 11–12°C. The dramatic variable is light, not temperature: about 21 hours of daylight at the June solstice shrink to about four hours in late December.
