IELTS writing: Demographic Changes in Yemen and Italy The four pie charts compare two countries regarding the percentage of population based on different age groups (0 to 14, 15-59, 60 and over) in 2000, and with a prediction into 2050. Overall, the proportions of young and middle-aged people in Yemen show a growing trend, while in Italy, it is the elderly people who will see their cohort expand. In 2000, people in Yemen who were aged below 60 years old took up a majority of 95.4% in its population, leaving only 3.6% to the elderly. Yet in Italy, the elderly accounted for almost a quarter of the total, and the middle group made up the biggest composition of 61.6%. The statistics are projected to change in the future. In Yemen, a growing share is predicted in the middle group, at 57.3% in 2050, overtaking the youngest group which will see its proportion shrink. On the other hand, elderly population is likely to increase in Italy, taking up 42.3% of the total, only next to the middle group which is expected to fall one-fifth in 2050. The proportions of the elderly group in Yemen and the youngest group in Italy are believed to remain stable.
