As dramatic as this growth would be, some regions of the world are expected to grow far more than others. More than half of the global population growth in the next 35 years is expected to happen in Africa, for example, but on the the other hand, some countries aren't expected to see any population growth at all.
In fact, the latest U.N. population report says 48 countries around the world are expected to see their populations decline by 2050. It also identifies 11 countries that, for reasons such as declining birth rates and emigration, are expected to lose more than 15 percent of their population in the coming decades.
If trends continue, things could get even more dramatic. According to the latest U.N. prediction, some countries are expected to lose more than half of their population by 2100. Of course, these are just projections and things could certainly go another way -- the United Nations believes there is a 23 percent chance the world's population will stabilize or even drop by 2100, for example.
