The charts depict the distribution of residents across three age groups in Oman and Spain in 2005, along with predictions for 2055.
In general, individuals aged 60 and above has constituted the largest proportion in both countries, projected to increase significantly in Oman, while experiencing a considerable decrease in Spain in 2055.
Oman exhibited the smallest share of 4% among those aged 15-59 years, with massively larger proportions in the other two age groups, each around half (48%) in 2005. However, forecasts for 2055 predict substantial growth of 57% among the eldest population and a notable decline to just above one-third (37%) in the youngest age group. Simultaneously, the remainder is anticipated to witness a slight increase to 6% by 2055. These trends indicate a shift towards older population.
Spain, conversely, displays a contrasting age distribution pattern. In 2005, approximately two-thirds (62%) of the population were aged 60 years and over, followed by nearly a quarter (24%) aged 15-59 years, whilst the remaining group accounted for 14%, roughly four times lower than the largest group. The projected figures for 2055 indicate a marked drop to under half (46%) and an almost doubling to 42% in the 15-59 years age group. Meanwhile, the 0-14 years sector is estimated to reduce lightly to 12%. These tendencies suggest a movement towards a younger demographic.
