The provided graph illustrates the proportion of the population in urban in four Asian countries starting from 1970 and ending with 2020, along with giving hypothesis about that for the next ten-year period, initiating from 2030.
Overall, all four countries describe a positive trend both in the past and the present. For some of the figures such as Thailand and Indonesia, their population kept on soaring for the whole data span while the figures of Malaysia and Indonesia constantly fluctuated during the survey time. By the end of 2040, Malaysia is predicted to be the highest population of the four, followed by Indonesia, Philippines and Thailand.
Out of the four countries, Malaysia and Indonesia have the most alike features throughout the seventy years span. During the first twenty years, Malaysia and Indonesia both went through a steady growth phase when Malaysia suddenly leaped more than fifteen percent from about forty five to over sixty percent. Similarly, a decade later, Indonesia followed by and settled itself at approximately forty five percent in 2010. Based on the predictions, Malaysia and Indonesia will have constant improvement throughout the remaining time, placing them at first and second rank, respectively.
Contrasted to the smooth transitions of Malaysia and Indonesia, Thailand and Philippines suffered from various fluctuations in their figures. Although both had a good start at first, in 1990, while Philippines persevered on a subtle decrease for the next twenty years, the latter went on a plateaued stage during its development until 2020. Fortunately, based on a supposition in the next decade from 2030 to 2040, Philippines will rise in its population at a moderate rate, while Thailand will have a tremendous raise of twenty percent, ranking them at third and fourth, respectively.
