About 28. The World’s Population

Global population surged from about 1.6 billion in 1900 to over 8 billion today due to advances in medicine, sanitation, and agriculture that drastically reduced mortality rates while birth rates remained high initially. This demographic explosion drove urbanization, resource consumption, and economic expansion but also strained ecosystems and infrastructure, especially in developing regions.

Population trends now vary widely, with aging societies in Europe and East Asia facing labor shortages and pension pressures while Africa and parts of South Asia experience youthful booms needing jobs and education. Managing these divergent trajectories is critical for sustainable development, migration policies, and global stability in the 21st century.
