Experts estimate that over 50% of the global population currently lives in cities, and by 2050, this percentage is expected to reach 70%. Megacities, defined as cities with over 10 million people, are becoming more common, and the concept of mega-regions, interconnected clusters of megacities, is also gaining prominence. These megacities often face challenges in accurately determining their population due to unclear boundaries and the inclusion of surrounding areas. Examples of megacities include Sao Paulo, New York, and Tokyo, which is the largest megacity in the world.
China boasts the largest mega-region, consisting of megacities like Hong Kong, Shenzhen, and Guangzhou. However, mega-regions can span multiple countries, as seen in West Africa, where Nigeria, Benin, Togo, and Ghana form a mega-region. These mega-regions hold significant economic power, with 66% of global economic activity and 85% of new technological and scientific advancements occurring within the 40 largest mega-regions. Despite this, less than 20% of the global population resides in these mega-regions.
In summary, urbanization continues to rise globally, with a majority of people living in cities. Megacities and mega-regions are becoming more prevalent, driving economic growth and technological advancements on a large scale.
