The two line graph indicates the global trend, urban and rural population and age structure respectively, by percentage from 1950 to 2040.
Overall, total population is rising throughout the first figure. In the second figure, only the 15 to 65 group of age structure are climbing in the period shown.
In 1950, both rural and urban population began at almost 5 percent, but urban population was slightly above. Later on, urban population continued to rise and expect to reach the peak of approximately 40% by the year 2040. In contrast, the rural population remained at the same level in the figure with unnoticeable changes.
In the second line graph, three groups of age structure began at around 5 percent in 1950, while only the group of 15-65 was above the line. In the following year, there was not significant changes to two groups besides the one of 15-65. However, the trend of 15-65 age structure began to increase since 1950 and expect to reach the peak of 35 percent at 2040 ultimately.
