The graphs illustrate how the population trends transform in 2 different resident areas, urban and rural, as well as how volume in various age brackets evolve from 1950 to 2040.
Overall, both areas witness an increasing trend; however, most people opt for urban area as a preferred choice throughout the surveyed period. On the other hand, the 16-65 and 65+ age cohorts display an upward trend from 1950 to 2040 while the remaining group shows a reverse pattern.
Regarding the inhabitation pattern, the urban area portion seems to rise gradually, starting from 8 millions in 1950 to 2.5 fold of its value in 2000, where it ends in a sudden surge to its all-time high of nearly 35 millions in 2040. Rural area also registers a similar trend, but to a lesser extent, only quadrupling its initial value over a 90-year period. Undoubtedly, the total population experiences a noticeable climb, which can be accounted by recorded growth of its individual categories.
Concerning the age compositions, 16-65 and 65+ are the 2 age brackets that witnesses escalation in their respective values, with 16-65 having more of a noticeable breakthrough throughout. The middle bracket is shown to make up the majority of the population in 1950, followed by 0-15 and 65+. This observation continued to be true until around the year 2000, when 0-15 age group encounters a sharp downturn while the 65+ picked up speed to its increase, resulting in the overlap of it their values in around 2010. Consequently, an opposite pattern emerge as the oldest cohort surpass that of the youngest during the rest of the period. Despite all the fluctuations in the other age group, 16-65 proves to consistently uphold its position as the highest population during the surveyed period.
