The table below compares actual and predicted figures for populations in three different cities.
The table compares the projected and real data for populations in three diverse cities: Sao Paulo, Jakarta, and Shanghai, over a 10-year period.
In 1990, Sao Paulo was recorded to hold the highest population, followed by Shanghai, whose figure is 2 units less. The actual figure for populations in Jakarta was the lowest at merely 9.5.
It can be seen that this pattern was estimated to remain unchanged in 2000. Another common trend predicted was that populations in these cities would all grow, in which the figure for Sao Paulo was expected to soar to 24. The data for populations in Jakarta and Shanghai was projected to undergo a moderate increase of 5 and 3.5, respectively.
Compared to the predicted figures in 2000, actual populations in Sao Paulo and Jakarta steadily rose by 3 units. Contrastingly, Shanghai’s real population in the same year experienced a slight drop to 12.5, which contradicts the estimated pattern.
