The graph gives information about the age of the population of Iceland between 1990 and 2020.
The bar chart illustrates the distribution of the population in Iceland across five age groups from 1990 to 2020.
Overall, the most significant change was observed in the 25–54 age group, which saw a considerable rise in its population share. In contrast, the younger age groups (0–14 and 15–24) experienced noticeable declines, while the proportions of older age groups remained relatively stable.
In 1990, the 25–54 age group accounted for roughly one-third of the population, but this figure rose sharply to nearly 50% by 2020, making it the largest demographic segment.
The 0–14 age group declined from slightly above 25% in 1990 to just under 20% in 2020. A more dramatic drop was seen in the 15–24 age group, which halved from just over 20% to just under 10% over the same period.
The 55–64 age group decreased modestly from 14% to about 10%, while the 65 and over age group remained relatively unchanged at approximately 13%.
