Answer:
In the coming decades, the vast majority of population growth is expected to occur in developing nations rather than developed nations. Here are some key points regarding both categories:
Developing Nations:
- Sub-Saharan Africa: Countries like Nigeria, Ethiopia, and the Democratic Republic of the Congo are projected to see significant population increases due to high fertility rates and improving healthcare.
- South Asia: Nations such as India and Pakistan will continue to grow, although India's growth rate is expected to slow down as it approaches replacement level fertility.
- Southeast Asia: Countries like Indonesia and the Philippines are also expected to experience population growth, though at varying rates.
- Middle East: Some countries in this region, particularly those with younger populations, may also see growth.
Developed Nations:
- Low Growth or Decline: Many developed nations, such as Japan, Germany, and Italy, are experiencing low birth rates and aging populations, leading to stagnation or decline in population.
- Immigration: Some developed countries may see population growth primarily through immigration, which can offset natural decline but does not lead to significant overall growth.
Conclusion:
Overall, the demographic trends indicate that developing nations will be the primary drivers of global population growth in the coming decades, while developed nations will face challenges related to aging populations and low birth rates.
