In 1970, he urban residents across the four countries are nearly equal, ranging between 15% and 30%. Indonesia and Malaysia showed a significant surge of city dwellers which continued to increase from 1970 to 1990. This is predicted to keep leaping to 40% and 45% respectively in 2040. Similarly, Thailand also experienced a steady rise, starting at 18% in 1970 and growing to 30% in 2020. Predictions indicate that the number will climb to 45% by 2040.
