The graph supports the statement that Africa's birthrate exceeds its death rate, showing a significant net population growth for the continent. High fertility rates in African nations contribute to this trend, with population expected to triple in these regions by 2100.
The statement that is supported by the data in the graph regarding the population growth in Africa is: 'Africa's birthrate exceeds its death rate.' This is evidenced by Figure 3.13, which shows Africa having the largest net population growth rate compared to other continents.
The United Nations Population Fund (2008) supports this by categorizing many sub-Saharan African nations as high fertility, expecting their population growth to triple between 2011 and 2100.
Additional information from the provided data indicates that high population growth occurs in less economically developed countries, particularly in Africa and Asia.
This growth is characterized by high fertility rates, which are significantly higher in Africa compared to other regions.
As such, this debunks the other potential statements, such as Africa reaching carrying capacity, having a low fertility rate, or lacking basic resources for population growth, none of which are supported by the given data.
