The bar chart illustrates the actual and anticipated population size in three cities from 1990 to 2000, with the figures measured in millions.
Overall, the actual and predicted figures of population differed. While the population of Jakarta and Sau Paulo were expected to increase, with the latter having the highest population, the population of Shanghai was forecast to decrease yet saw a modest growth.
Starting with Jakarta, the population of this city stood at around 8 million in 1990. Then, the figure was projected to increase slightly to roughly 11 million: however, the population actually surpassed the prediction, rising to 13 million, staying the least populated city. Similarly, Sao Paulo recorded by far the highest population size; nearly 17 million in 1990, followed by a forecast growth to 22 million. But, in reality, the figure exceeded the expectation and rose further to 24 million, remaining the most populated city.
In contrast, Shanghai started with 13 million population in 1990. However, the figure was anticipated to decline slightly to 11 million, which actually increased to 15 million in 2000.
