The given pie charts give information about the ages of the populations of two different countries, Oman and Spain, in the year 2005 and predictions for the year 2055. The data is given in percentages.
It can be seen from the charts the age group of the population of Oman. In the year 2005, the population in the age group 0 to 14 years and the age group 60+ years were both the same—48 percent of the population equally—and only 4 percent of the population was 15 to 59 years, which was the lowest population in the year 2005. While, the prediction for the year 2055, the age groups of 0 to 14 years and 60+ years will be 37 percent and 57 percent, respectively. The age group 15 to 59 years will be predicted to be only 6 percent.
Furthermore, consider the population of Spain. In the year 2005, the 0 to 14 years age group was only 14 percent, which was the lowest age group, whereas the age groups of 15 to 59 years and 60+ years populations were 24 percent and 62 percent, respectively. While, the prediction for the year 2055, the age groups of 0 to 14 years and 60+ years populations will decrease to 12 percent and 46 percent, and the 15 to 59 years age group will increase to 42 percent.
Overall, Oman will have more older people and fewer middle-aged adults, while Spain will have fewer children and elders but more working-age adults in the year 2055.
