The given pie charts compare the age of populations in Yemen and Italy in 2000 and give projections for 2050, dividing them into three different groups.
Overall, it is clear that Yemen is expected to experience a large increase in the proportion of working-age people, whereas Italy is projected to face serious population ageing. In both countries, the percentage of children is forecast to go down, but the proportion of elderly people will rise much faster in Italy.
Looking closely at Yemen, people aged 0-14 made up 50.1% of the population in 2000, which was the largest group, slightly ahead of the 15-59 age group at 46.3%. The remaining people were aged 60 or more, accounting for 3.6%. By 2050, however, the working-age population is predicted to become the biggest group, increasing to 57.3%. On the other hand, the proportion of children is expected to fall to 37%, while the elderly population will grow slightly to 5.7%.
Italy shows a very different trend. In 2000, the 15-59 age group was the majority at 61.6%, followed by those aged 60 and over at 24.1%. Children were the smallest part of the population at 14.3%. By 2050, the share of working-age Italians is projected to decrease to 46.2%, while the proportion of elderly people will climb sharply to 42.3%. Meanwhile, the percentage of children is expected to drop to 11.5%.
