Both given graphs depict transformations in the tendencies of the urban and countryside population, as well as the diversity of age groups between 1950 and 2040.
Overall, from 1950 to 2000, for the population line graph, the number of residents in urban areas also in total gained substantially except the steady growth in the rural one. In addition, the 16-65 age group escalated dramatically, otherwise; the rests have stayed low for 50 years. These trends are predicted to go on until 2040
The number of people in rural areas has seen a slight change and is projected to do the same over the period of 1950 to 2040. In contrast, the number of people living in urban areas has changed significantly and is projected to keep following the same trend until 2040. The total shares are almost alike the trend of urban areas.
Regarding the change in the age groups, despite there being minor changes in both the under 15 and over 65 years age groups, both of the trends are almost the same and comprised of about 5 million. On the other hand, the age group of 15 to 65 has seen and is projected to see an increase, and the number is expected to grow to 35 million people, which was almost 6 million in 1950.
