The pie charts illustrate the changes in the age distribution of people in Oman and Spain from 2005 to 2055.
Overall, the majority of the population in both Oman and Spain was over 60 years old in 2005, and this trend continues in 2055. However, the second largest age group in Oman consists of individuals under 14 years old for both 2005 and 2055. In contrast, in Spain, the second largest age group comprises those aged 15 to 59 years within this half-century period.
In Oman, the percentage of people over 60 years and under 14 years old was 48% in 2005. The pie chart for 2055 indicates a dramatic increase in the population aged over 60, projected to reach 57% by that year. Meanwhile, the under 14 age group is expected to decrease by 10%. Additionally, the percentage of people between 15 and 59 years old is anticipated to rise slightly by 2055.
In Spain, the population aged over 60 was 62% at the end of 2005, but this figure is projected to drop to 46% by 2055. The age group of 15 to 59 years old accounted for 24% of the population in 2005, and a significant increase to 42% is expected by 2055. There will be a slight decline in the under 14 years age group over this half-century.
