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.

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...,

The population in Iceland increased steadily over the past 10 years. Of the 387,758 people living in Iceland at the beginning of 2023, people between 20 and 39 years of age made up the largest age group. The second largest age group was those aged 40 to 59 years. Above 13,000 people aged 80 years or more live in Iceland. The Icelandic population consists of more men than women.

Level and partitioning of genetic diversity is expected to vary between contrasting habitats, reflecting differences in strength of ecological and evolutionary processes. Therefore, it is necessary to consider processes acting on different time scales when trying to explain diversity patterns in different parts of species' distributions. To explore how historical and contemporary factors jointly may influence patterns of genetic diversity and population differentiation, we compared genetic composition in the perennial herb Arabidopsis lyrata ssp. petraea from the northernmost parts of its distribution range on Iceland to that previously documented in Scandinavia. Leaf tissue and soil were sampled from ten Icelandic populations of A. lyrata. Seedlings were grown from soil samples, and tissue from above-ground and seed bank individuals were genotyped with 21 microsatellite markers. Seed bank density in Icelandic populations was low but not significantly different from that observed in Norwegian populations. While within-population genetic diversity was relatively high on Iceland (HE = 0.35), among-population differentiation was low (FST = 0.10) compared to Norwegian and Swedish populations. Population differentiation was positively associated with geographical distance in both Iceland and Scandinavia, but the strength of this relationship varied between regions. Although topography and a larger distribution range may explain the higher differentiation between mountainous Norwegian relative to lowland populations in Sweden, these factors cannot explain the lower differentiation in Icelandic compared to Swedish populations. We propose that low genetic differentiation among Icelandic populations is not caused by differences in connectivity, but is rather due to large historical effective population sizes. Thus, rather than contemporary processes, historical factors such as survival of Icelandic lineages in northern refugia during the last glacial period may have contributed to the observed pattern.

Over the last decade, there were constantly more men than women living in Iceland. Moreover, the gap increased from 2013 to 2023. While there were around 1,000 more men than women in 2013, this number had increased to over 10,000 by 2023. That year, there were around 200,000 men and 188,000 women living in Iceland. The total number of inhabitants in the country was 387,758 at the beginning of 2023.

There were 346 300 Facebook users in Iceland in April 2023, which accounted for 95.7% of its entire population. The majority of them were women - 52.3%. People aged 25 to 34 were the largest user group (76 100). The highest difference between men and women occurs within people aged 65 and above, where women lead by 19 100.

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.
