The pie charts compare the distribution of different age groups in two different years, 1983 and 2003.*
Overall, there was a noticeable shift in the age composition over the two decades, with a significant increase in the proportion of older people (55+ years) and a decline in the percentage of younger age groups (25-34 years and 35-54 years).
In 1983, the largest age group was those aged 35-54, making up 50% of the total population. This figure declined sharply to 35% in 2003. Similarly, the 25-34 age group also saw a reduction from 20% in 1983 to 12% in 2003. Conversely, the proportion of people aged 55 and above rose substantially from 16% to 26%, indicating an aging population trend.
Moreover, there was a slight increase in the proportion of younger individuals. The 0-15 age group accounted for 10% in 1983 and grew to 12% in 2003. Additionally, the 16-24 age group, which was not specified in 1983, represented 15% of the population in 2003.
In conclusion, the data highlights a significant aging trend, with an increasing proportion of older individuals and a decline in the working-age population.
