Answer:
Africa is the region that has population growth based on a high total fertility rate.
Step-by-step explanation:
On this graph, we can see that the predictions for the global population are that it will continue to grow. That is not to say that there will be proportional growth in all regions though, as there are differences from one region to another. There's one region that will have exponential growth, one that will have minor growth, two will stagnate, and one will actually experience a slight decline.
The only region that will have a big population growth is Africa. The reason for this is that this region is predicted to retain its very high total fertility rate. With the living conditions gradually improving over time, especially the healthcare system, this will lead to big decline in the mortality rate, which will even more pronounce the large fertility rate, so the population will rapidly grow.
