The given bar charts present the age distribution of the populations in Yemen and Italy for the year 2000 and projections for 2050. The data is divided into three age groups: 0-14 years, 15-59 years, and 60+ years.
In summary, Yemen’s population is projected to become more balanced across the age groups, with a notable increase in the middle-aged population and a decrease in the younger population. Conversely, Italy is expected to see a significant aging of its population, with a dramatic increase in the proportion of elderly people and a decrease in the working-age population.
In Yemen, the population in 2000 was predominantly young, with 50.1% of the population aged 0-14 years. This proportion is expected to decrease significantly to 37% by 2050. The middle-aged group (15-59 years) comprised 46.3% in 2000 and is projected to rise to 57.3% in 2050. The elderly population (60+ years) was a small fraction at 3.6% in 2000, with a slight increase to 5.7% anticipated by 2050.
In contrast, Italy had a much older population structure in 2000, with only 14.3% in the 0-14 age group, which is expected to decline further to 11.5% by 2050. The middle-aged group (15-59 years) represented the majority at 61.6% in 2000 but is projected to decrease sharply to 46.2% by 2050. The elderly population (60+ years) constituted a significant 24.1% in 2000 and is expected to grow substantially to 42.3% by 2050.
