The charts illustrate the distribution of residents across three age groups in Oman and Spain in 2005, along with predictions for 2055.
Overall, individuals aged 60 and above have constituted the largest proportion in 2005 in both countries, with a significant increase projected for Oman and a considerable decrease expected for Spain by 2055.
In 2005, Oman exhibited the smallest share, at 4%, among those aged 15-59, with much larger proportions in the other two age groups, each around 48%. However, forecasts for 2055 predict substantial growth of 57% among the eldest residents, a notable decline to just above one-third (37%) in the youngest age group, and a slight increase to 6% for the remainder. These trends indicate a shift towards an older population in Oman.
On the other hand, Spain represented a distinctive age distribution: about two-thirds of the population was aged 60 years and over, with around a quarter in the 15-59 bracket, leaving approximately 14% in the remainder, roughly a quarter of the largest group. The projected figures for 2055 indicate a decline to 46% in the eldest bracket and an almost doubling to 42% amidst those aged from 15 to 59 years. The 0-14 sector is estimated to slightly reduce to 12%. These tendencies suggest a movement towards a younger demographic in Spain.
