The bar chart illustrates the actual and forecasted population figures for three cities: Jakarta, Sao Paulo, and Shanghai, from 1990 to 2000, with the units measured in millions.
Overall, populations in 1990 were considerably lower than those in 2000. Although the populations of the three cities were predicted, the actual figures were higher than the predictions, with Sao Paulo topping the list throughout the period.
As for the figures for Jakarta and Shanghai, the former accounted for roughly 8 million residents in 1990. Even though it was predicted that it would go up to about 11 million people, in reality, it grew further to 13 million inhabitants. With respect to Shanghai, it constituted around 12 million individuals initially, and it was thought that it would exhibit a decline to 11 million population. However, according to the actual figures, it increased to hit a peak of 15 million residents.
In contrast, the figure for Sao Paulo was by far the most significant in terms of population size in every year. In 1990, it made up approximately 17 million population, but with it being predicted, it surged to 22 million people, while the actual figure witnessed a substantial increase to about 24 million in 2000, being the largest figure in the period.
