Historical dataset showing Iceland population density by year from 1961 to 2022.

Population density (people per sq. km of land area) in Iceland was reported at 3.9011 sq. Km in 2023, according to the World Bank collection of development indicators, compiled from officially recognized sources. Iceland - Population density (people per sq. km) - actual values, historical data, forecasts and projections were sourced from the World Bank on October of 2025.

Iceland IS: Population Density: People per Square Km data was reported at 3.404 Person/sq km in 2017. This records an increase from the previous number of 3.346 Person/sq km for 2016. Iceland IS: Population Density: People per Square Km data is updated yearly, averaging 2.522 Person/sq km from Dec 1961 (Median) to 2017, with 57 observations. The data reached an all-time high of 3.404 Person/sq km in 2017 and a record low of 1.786 Person/sq km in 1961. Iceland IS: Population Density: People per Square Km data remains active status in CEIC and is reported by World Bank. The data is categorized under Global Database’s Iceland – Table IS.World Bank: Population and Urbanization Statistics. Population density is midyear population divided by land area in square kilometers. Population is based on the de facto definition of population, which counts all residents regardless of legal status or citizenship--except for refugees not permanently settled in the country of asylum, who are generally considered part of the population of their country of origin. Land area is a country's total area, excluding area under inland water bodies, national claims to continental shelf, and exclusive economic zones. In most cases the definition of inland water bodies includes major rivers and lakes.; ; Food and Agriculture Organization and World Bank population estimates.; Weighted Average;

Population density of Iceland went up by 2.55% from 3.7 people per sq. km in 2021 to 3.8 people per sq. km in 2022. Since the 0.53% improve in 2012, population density rocketed by 18.42% in 2022. Population density is midyear population divided by land area in square kilometers.

3.8 (people per sq. km) in 2022. Population density is midyear population divided by land area in square kilometers.

This statistic shows the distribution of the population in Iceland as of 2019, by dwelling type. In that year **** percent of the Icelandic population lived in detached houses and **** percent occupied semi-detached houses.

Comprehensive socio-economic dataset for Iceland including population demographics, economic indicators, geographic data, and social statistics. This dataset covers key metrics such as GDP, population density, area, capital city, and regional classifications.

Denmark has, by far, the highest population density of the Nordic countries. This is related to the fact that it is the smallest Nordic country in terms of land area. Meanwhile, Iceland, which has the smallest population of the five countries, also has the lowest population density. As the total population increased in all five countries over the past decade, the population density also increased.

Estimates, total number of people per grid-cell. The dataset is available to download in Geotiff format at a resolution of 3 arc (approximately 100m at the equator). The projection is Geographic Coordinate System, WGS84. The units are number of people per pixel. The mapping approach is Random Forest-based dasymetric redistribution.

We compared population trends for rock ptarmigan (Lagopus muta) densities (2003‒2019) derived from walked transects and driven road transects in Mosfellsheiði and Slétta in southwest and northeast Iceland, respectively. The walked transects were laid out according to a random rule. Convenience-based road transects could give biased population density estimates if roads affect the distribution of ptarmigan. We used distance sampling to compare density estimates provided by the two survey types. Our results showed that road transects were more than five times faster to conduct than walked transects. Estimated ptarmigan density changed in synchrony for the two survey methods in both study areas. Mean density estimates in Mosfellsheiði were similar for the two survey methods (walked transects 1.6 males × km-2, 95% CI 1.4‒1.8; road transects 1.7 males × km-2, 95% CI 1.4‒2.0), but not in Slétta, where density estimates for road transects were significantly lower (walked transects 5.2 males × ..., Study area

Our study occurred in two distinct areas, one in southwest Iceland called Mosfellsheiði (N64.13591, W21.44585) and the other in northeast Iceland called Slétta (N66.4683, W16.476; Fig. 1). The linear distance between the two areas is 360 km. The Mosfellsheiði study area (210 km2) is 15 km from the coast and has altitudes ranging from 200 to 400 m above sea level. The Slétta study area (50 km2) is close to the coast, and altitudes range from sea level to approximately 40 m above sea level. The landscape on Slétta is best described as flat or gently undulating; on Mosfellsheiði, the ground is less flat, with low ridges and shallow depressions between them. Both study areas are treeless. The habitat types on Mosfellsheiði were more variable than those on Slétta. The dominant habitat types on Mosfellsheiði were mosslands (57%) and heathlands (23%), but other components included lava fields (7%), wetlands (7%), and fell fields, moraines, and sands (combined 4%).

Description of the data and file structure

Spring surveys of territorial ptarmigan males have been used to derive annual densities in Iceland. These counts were started in the early 1960s using the territory mapping method on designated plots, but since 1999, walked and road (driven) transects have been included, applying the distance sampling technique to collect and analyze the transect data. While the territory mapping method assumes the detection of all individuals on the designated plot, distance sampling considers variable detection probabilities based on the distance from the transect and other covariates. Road transects for ptarmigan are less demanding than walked transects. Still, they may break one of the basic assumptions of distance sampling, namely random spacing of tran...,

In Iceland, nearly 60 percent of the population were members of the Evangelical Lutheran Church of Iceland, making it the religious organization in the country with the highest share of members. Moreover, nearly one fifth of the population belonged to other organizations or did not specify their community, while eight percent did not belong to a religious organization.

This study aims to explain the distribution, maturity and population structure of Meganyctiphanes norvegica and Thysanoessa inermis in springtime in relation to main hydrographic regions around Iceland: Atlantic in the southwest, Atlantic-Arctic mixture in the north and Arctic in the east. Krill were collected 14-29 May 2013 using a macrozooplankton trawl. Biomass of both species combined was significantly higher in southwest than in north and east. M. norvegica clearly dominated in Atlantic waters, whereas T. inermis was more evenly distributed around the island, while the highest values were also observed in the southwest for this species. Simple linear regressions showed that the abundance of M. norvegica was positively related to temperature, salinity and phytoplankton concentration, while the abundance of T. inermis was negatively related to bathymetry. Multiple linear regression analyses did not add to this information of a positive relationship between abundance and temperature for M. norvegica, while T. inermis was shown to be negatively related to both temperature and bathymetry. During the latter half of May, the main spawning of both species was confined to the regions off the southwest coast. Sex ratio (males/females) of M. norvegica was higher in southwest than in the north and east, whereas T. inermis showed a similar sex ratio all around the island. In all regions, M. norvegica appears to have a life span of 2-years while T. inermis of 1-year in the southwest and possibly 2-years in north and east.
