The given bar charts compared the population in two countries Yemen and Italy in terms of the ages in 2000 and estimated percentage for 2050.
Overall, people aged between 15 and 59 years have the biggest proportions on each diagram.
To start with Yemen, children and adolescents up to 14 years stood at nearly half of the total population in 2000. However, this figure is set to decline to 37% in 2050. The middle-aged group had the second largest share just over 45% in 2000, which is speculated to increase to 57.3% in the future. The most modest percentage was for older people in 2000 and 2050, nearly 4% and 6% respectively.
In terms of Italy, the category of 0-14 years had the least percentage in both years, from 11 to 15, while the older generation accounted for almost a quarter in the year 2000 and is projected to reach more than 40% in 2050. In 2000, 61.6% of people were between 15 and 59 years old, but it will rapidly drop to just over 45%.
