2066 Population

By the year 2066, the world’s population is projected to reach around 10 billion people, though estimates vary depending on fertility trends and policy changes. Asia will remain the most populous continent, with countries like India and China each sustaining populations well over a billion, though India is expected to have surpassed China as the world’s most populous country. Africa will experience the fastest population growth, with its total population potentially doubling to over 2.5 billion, making Nigeria the third most populous country globally. Europe’s population will likely decline due to low birth rates and aging demographics, while North America’s growth will be moderate, driven largely by immigration. Latin America and the Caribbean will see slower growth, with populations stabilizing in countries like Brazil and Mexico. Oceania, led by Australia, will continue to grow slowly but steadily. Urbanization will intensify, with megacities proliferating in Asia and Africa, while rural populations shrink across most regions.
