The global population is constantly on the rise. There are significant demographic differences around the world, and i general they can be taken regionally.
- Europe, the Americas, and East Asia tend to have low birthrates and low mortality rates. This leads to aging populations, and gradually the populations will start to stagnate and even decrease.
- On the other side, Africa, South Asia, Southeast Asia, the Middle East, are regions that have very high birthrates, and even though the mortality rates are much higher than the previously mentioned regions, they still manage to have big increase in their population.
- In a way, this disproportion is actually balancing the global population, so its rise is not as dramatic as in the past. It is expected that the population will continue to rise, but that the rise will constantly go down.
