Which region is expected to account for more than one third of world population growth between 2000 and 2050?

The correct response highlights Africa as the region expected to account for more than one third of world population growth between 2000 and 2050. This can be attributed to several demographic trends observed throughout the continent. Africa has one of the highest fertility rates in the world, along with a relatively young population, which contributes significantly to its population growth. Additionally, improvements in healthcare and living conditions have led to increased life expectancy, further fueling population increases.

In contrast, regions like Europe are experiencing declining or stagnant population growth due to lower birth rates and aging populations. Similarly, North America has a relatively stable population growth that is more influenced by immigration rather than high birth rates. Asia, while still a populous region, has many countries experiencing slowed growth rates and aging populations, particularly in places like East Asia, where demographic challenges are becoming more prominent. Thus, the unique demographic dynamics of Africa distinctly position it as the primary contributor to global population growth during this period.
