Band 9: The graph gives information about the age of the population of Iceland between 1990 and 2020. Summarize the information by selecting and reporting the main features, and make comparisons where relevant.

The graph illustrates changes in the age structure of Iceland’s population between 1990 and 2020, divided into three age groups.

Overall, the working-age population remained the largest group throughout the period, while the proportion of elderly people increased steadily. In contrast, the share of children showed a slight decline.

In 1990, people aged 15-64 accounted for the majority of the population. Although this group continued to dominate in 2020, its proportion fell slightly over the 30-year period. Meanwhile, the population aged 65 and over rose gradually, indicating an ageing population. By 2020, this group represented a noticeably larger share than in 1990.

Conversely, the percentage of children aged 0-14 decreased modestly over time. While this age group formed a significant portion of the population at the beginning of the period, its share was smaller by 2020.

In summary, Iceland experienced a gradual demographic shift between 1990 and 2020, characterised by population ageing, a slight reduction in the working-age group, and a decline in the proportion of children.
