The four provided pie charts illustrate the population distribution of two countries, Yemen and Italy, across three age groups; zero to fourteen years, fifteen to sixty years, and more than sixty years for the years 2000 and 2050.
Yemen has witnessed a significant decline in its child population, falling from fifty point one percent to thirty-seven percent. Conversely, Italy’s child population has remained relatively stable. Concurrently, Yemen’s working-age population has seen a substantial increase, from forty-six point three percent to fifty-seven point three percent, and this trend is expected to continue. However, Italy’s working-age population, which was once the largest demographic, has declined from sixty-one point six percent to forty-six point two.
The Italian elderly population has experienced a rapid increase in its elderly population, rising from twenty-four point one percent to forty-two point three percent, while Yemen has seen only a modest growth in this demographic, from three point six percent to five point seven percent.
Overall, while Yemen experienced a notably young population in 2000, with a significant proportion of the population under the age of 14, Italy exhibited a more balanced age structure. However, projections for 2050 indicate a dramatic shift towards an older population in Italy, accompanied by a decline in the younger age groups. In contrast, Yemen is predicted to undergo a demographic transition, with a decreasing youth population and a growing working-age population.
