Study Figure 3b, which shows the population and predicted population growth for selected rapidly growing African cities between 2005 and 2040.
A data table displaying population figures in millions for three African cities (Lagos, Kinshasa, and Luanda) in 2005 and projected for 2040. Lagos increases from 11.2 million to 29.8 million; Kinshasa increases from 7.5 million to 24.0 million; Luanda increases from 3.8 million to 11.5 million.
| Year | Lagos (millions) | Kinshasa (millions) | Luanda (millions) |
|---|---|---|---|
| 2005 | 11.2 | 7.5 | 3.8 |
| 2040 (Predicted) | 29.8 | 24.0 | 11.5 |
Suggest one reason for the trends shown in Figure 3b.
