By the year 2051, the world’s population is projected to reach approximately 9.7 billion people, according to United Nations estimates. Asia will remain the most populous continent, with countries like India and China each sustaining populations exceeding 1.3 billion, though India is expected to have surpassed China as the world’s most populous country. Africa will experience the fastest growth, with its population potentially doubling to over 2.5 billion, driven by high birth rates in countries such as Nigeria, Ethiopia, and the Democratic Republic of the Congo. Europe’s population is likely to decline slightly, reflecting aging demographics, while North America’s population will grow modestly, mainly due to immigration, reaching around 400 million. Latin America and the Caribbean will see slower growth, with Brazil and Mexico continuing as the region’s largest countries. Oceania, led by Australia and Papua New Guinea, will remain the least populous continent, but will still experience moderate growth. Urbanization will intensify, with the majority of the global population living in cities, and megacities in Asia and Africa becoming increasingly prominent.
