The provided two line graphs illustrates world population percentage index and 3 type age structure. The data are from 1950 to 2040.
Overall, it can be seen that urban and total population percentage is parallely incline but rural population is constantly grow over the timeline. On the other hand, 15-65 age group significantly increasing meanwhile under 15 and over 65 age group steadily move in straight line.
The world population trends chart indicates that in 1950, urban and rural populations rate was at below 10% and Overall populations was nearly 10%. Duration between 1970-1980, urban population figures were entered to 20% at same period total population rate cross 20% and remains both population grew nearly upto 30%-40% at end of 2020. However, it predict that in between 2030 to 2040, urban and total people will cross to 30% and 40% respectively. Furthermore, rural popularize are unchanged.
On the other hand, age structure trends shows that there be no noticeable change in above 65 and below 15 age after 1970, but before 1950-1960, minor group was at 5% and it will reached to above 5%. In contrast, 15-65 age range considerly increase every 10 year and will final at 35%.
