The pie charts illustrate the distribution of age groups in Yemen and Italy in the year 2000 and projections for the year 2050.
In Yemen in 2000, the population was predominantly young, with 50.1% aged 0-14 years and only 3.6% aged 60 or above. The working-age group (15-59 years) made up 46.3%. By 2050, it is projected that the proportion of children will decrease to 37.0%, while the working-age population will rise significantly to 57.3%. The elderly population will also grow slightly to 5.7%.
In contrast, Italy in 2000 had a much older population structure. The largest group was those aged 15-59 years, comprising 61.6%, followed by 24.1% aged 60 and above, and only 14.3% aged under 15. However, by 2050, a dramatic shift is expected: the elderly will make up the largest proportion at 42.3%, while the working-age population will decline to 46.2%. The youngest group will also shrink to 11.5%.
Overall, Yemen is expected to remain a relatively youthful country, although the proportion of working-age and elderly people will increase. Italy, on the other hand, is forecast to undergo significant population ageing, with a large rise in the elderly group and a notable decline in both children and working-age people
