Peak Population: When Will It Hit The World's 40 Largest Countries

The world's population growth is diverging, with some nations shrinking while others continue to expand. China's population peaked in 2021 and is now declining, raising concerns about its aging workforce. Japan, South Korea, Thailand, and Germany have also reached their population peaks in recent years. Factors like urbanization, education costs, and low fertility contribute to Asia's demographic slowdown. The U.S. is projected to continue growing due to inward migration offsetting low fertility rates. Nigeria, Ethiopia, Tanzania, and the Democratic Republic of Congo are expected to grow significantly past 2100. These African nations could more than double in population due to high birth rates and improving child survival. Population peaks and declines influence economic shifts, affecting workforces, pension systems, and demand for resources. This demographic map serves as a key indicator of future consumption, labor, and geopolitical power.
