2042 Population

By the year 2042, the world’s population is projected to reach approximately 9.2 billion people, reflecting ongoing growth but at a slowing rate compared to previous decades. Asia will remain the most populous continent, with countries like India and China each sustaining populations well over 1.4 billion, though India is expected to maintain its position as the world’s most populous country. Africa will experience the fastest population growth, with its total population likely surpassing 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 expected to decline slightly, falling below 700 million, due to aging demographics and low fertility rates, while North America’s population will grow modestly, primarily through immigration, reaching around 400 million. Latin America and the Caribbean will see slower growth, with Brazil and Mexico remaining the largest countries in the region. Oceania, led by Australia and Papua New Guinea, will continue to have the smallest population, but will experience steady growth. Urbanization will intensify, with the majority of people living in cities, and several megacities—particularly in Asia and Africa—surpassing 30 million residents.
