The provided chart illustrates the proportion of the population in four Asian countries (Philippines, Malaysia, Thailand, Indonesia) between 1970 and 2020, with forecasts for 2030 and 2040.
Overall, Malaysia would demonstrate the highest rise at the end of the period; however, Thailand would have the fewest population by 2040 compared to others. Meanwhile, Indonesia with the lowest number at the beginning and Philippines would be recorded at average rate by 2040.
In 1970, the population in Malaysia was noted at 30%. During the period, the figure began to increase considerably, representing approximately 75% by 2020. Regarding foreseeable predictions, twenty years later, the number will boost to virtually 81-82%, being the largest among the others. By comparison, Indonesia had the lowest figure in 1970 (about 14%). Nevertheless, Indonesian population increased significantly over the entire period, illustrating around 48% by 2040, the second highest percentage.
Concurrently, the proportion of the Philippines population underwent slight fluctuations during the time, standing at around 45% by 2020. After two-decade period, the figure will rise marginally to approximately 55%. Additionally, Thai population experienced a steady growth throughout the time, growing from virtually 18-19% to almost 48%.
