The two images above display the differences in trends regarding “urban and rural populations” and “trends in different age groups” from 1950 to 2040.
Overall, the first graph, which is about the urban and rural population trends, consists of three lines in total, representing urban and rural populations respectively. The second graph, however, shows lines representing ages ranging from 0-15, 16-65, and over 65 in the same time interval. In both graphs, there is an upward trend, with the “total” and “16-65” lines starting at the highest points and increasing the most.
Firstly, starting from around 8 and 2 and ending at 15 and 6, urban and rural populations increased somewhat linearly from the year 1950 to 2000. The same can also be said for the two lower age groups in the second image. The group 0-15 ends at the value of 6, only 2 higher than the start. In parallel, the age group of over 65 started at 3 and expanded to 5. For the two highest lines in the two graphs, the “total” line and the “15-65” line, both started at around 10 and ended at 26 for the previous line and 24 for the latter category.
Ultimately, in the last interval spanning from 2000 to
2040, 5 out of six lines have a steep rise; only the “0-15” group has a decrease. The total line, which is the sum of both urban and rural values, ended at around 45, almost five times higher than the starting value. The two age groups that still have an upward trend in the second graph have a value of 27 for “16-65” and 9 for the “65+” age group in 2040. The only line that has a downgrade ended at around 5, 4 values lower than what it had in the year 2000.
