The bar chart provides information on the age demographics of Iceland’s population over a 30-year period, from 1990 to 2020.
What is most striking when looking at the data is that the age group of 25-54 continues to be the largest demographic in the population of Iceland, whereas the number of people aged 0-24 experiences a gradual decrease over the period shown. It is also important to note that the population aged 55 and above shows only marginal changes throughout the years among the four demographic groups.
Focusing first on the group with a roughly consistent increase in numbers, the population aged 25-54 made up about one-third of Iceland’s population in 1990, being the most popular age group at the time. By 2020, the number of people in this group had grown to about half of the total population. This is not only the largest increase over the given timeframe, but it also highlights the enduring dominance of this age group over the others throughout the years.
In stark contrast to the consistent growth of the 25-54 age group, the population under the age of 25 in Iceland experiences a gradual decline over time. Specifically, the 0-14 age group and the 15-24 age group both witness a notable decrease. The former declines from over one-fifth of the population to less than one-tenth, while the latter drops from over one-fifth to just below 20% by 2020. Despite these declines, the 15-24 age group still maintains its position as the second-largest demographic, whereas the 0-14 age group becomes the smallest demographic by the end of the 30-year period surveyed.
Finally, the only age groups to experience minimal change during this period are those aged 55 and above. The number of people in these groups consistently hovers around 10-15% of the total population, reflecting relatively stable numbers over the years.
