The provided line graph illustrates the proportion of the population living in cities in four Asian countries from 1970 to 2020, with predictions for 2030 and 2040.
Overall, the percentage of urban residents in all four countries shows an upward trend over the period. Malaysia is expected to maintain the highest percentage of city dwellers, while Thailand is projected to have the lowest figure by the end of the period.
Starting at around 30% in 1970, the proportion of people living in cities in Malaysia grew steadily to nearly 80% in 2020, and it is predicted to reach almost 90% by 2040. Meanwhile, the Philippines began with about 30% in 1970 and rose to roughly 50% in 1990, but then fluctuated around 45% before reaching nearly 50% in 2020. It is projected to increase moderately to under 60% by 2040.
On the other hand, Indonesia started with the lowest proportion at under 20% in 1970, but saw a strong rise to around 55% in 2020, and is expected to reach over 65% by 2040. Thailand had approximately 18% in 1970 and grew steadily to around 35% in 2020. It is projected to continue increasing to just over 50% by the end of the timeframe.
