The provided graph illustrates the proportion of the city inhabitants in four countries of Asia (Philipines, Malaysia, Thailand, Indonesia) between 1970 and 2020, along with the projections for the next two decades.
Overall, it can be seen that most of the people moved to cities during this period in all the countries stated. The country with the most metropolitans is Malaysia, after increasing dramatically.
In detail, Malaysia and Indonesia started with exactly 30%, and almost 15% respectively rose steadily in the fifthy-year period. Thailand followed the same path with Malaysia and Indonesia, and rose about 10% (from almost 20% to 30%) from 1970 to 1990. Then, it plateaued for 30 years until 2020. The Philippines, after remaing steady for 10 years, reach a peak of just under 50% from about 35% in 1990. However, it fell to just over 40% in 2010, before starting to grow relatively.
The predictions show that the population living in cities will grow gradually from 2020 to 2040. In 2040, Malaysia is forecast to have the most percantage at about 80%, then followed by Indonesia at approximately 60%, the Philippines at roughly 55%, and Thailand at 50%.
