Urbanization has become one of the defining trends of the 21st century, with more than half of the global population now residing in cities.
According to projections by the United Nations, this trend is only set to intensify, with an estimated 68% of the world’s population expected to be living in urban areas by the year 2050.
UN Forecasts 68% Global Urbanization by 2050
As the world continues to urbanize, certain regions, particularly Asia and Africa, will see the most significant growth, with nearly 90% of urban expansion predicted to occur in these areas.
The definition of what constitutes a city varies widely across different regions and countries. The lack of standardized international criteria for delineating urban boundaries often leads to multiple definitions for the same urban area.
Despite these challenges, the United Nations provides valuable insights into the growth and composition of the world’s largest urban agglomerations.
Delving into the data, we find that some of the world’s most populous urban areas are experiencing remarkable growth. Let’s take a closer look at the top 5 urban giants and the unique characteristics that define them:
- Osaka, Japan
Population (2020): 19.17 million
Once the capital of Japan, Osaka boasts a rich cultural heritage, being the birthplace of Bunraku, a traditional Japanese puppet theater. Renowned as “The Nation’s Kitchen,” Osaka historically played a crucial role in Japan’s economy and trade during the 17th century.
- Mumbai, India
Population (2020): 20.41 million
Formerly known as Bombay, Mumbai stands as India’s leading financial hub, housing the Bombay Stock Exchange. The city is undergoing rapid expansion, with plans for the introduction of high-speed passenger railway services to accommodate its growing population. Mumbai also showcases innovative initiatives like the “ladies special” train service, catering exclusively to female commuters during peak hours.
- Beijing, China
Population (2020): 20.46 million
As the capital of China, Beijing holds significant political and cultural importance. Situated along the Great Wall of China, it stands as one of the nine Chinese provinces and municipalities. Despite China’s efforts to address declining birth rates through policy changes and incentives, Beijing, like many other Chinese cities, grapples with demographic challenges.
- Cairo, Egypt
Population (2020): 20.9 million
Cairo, the capital of Egypt, is a bustling metropolis steeped in history. Home to iconic landmarks such as the Great Pyramid of Giza, the city attracts tourists from around the globe. However, rapid population growth coupled with environmental concerns pose significant challenges for urban planners in Cairo.
- Dhaka, Bangladesh
Population (2020): 21.01 million
Bangladesh’s largest city, Dhaka, stands out for its staggering population density, nearly double that of Manhattan. The city faces numerous issues exacerbated by climate change, including frequent flooding and displacement of low-income migrants. These challenges underscore the urgent need for sustainable urban development strategies.

Exploring the Diverse Tapestry of Urbanization
Beyond these top urban giants, other cities like Mexico City, with its unique blend of ancient farmland and modern urban infrastructure, offer further insights into the diverse landscape of urbanization.
As the world marches towards an increasingly urban future, understanding the dynamics of urban growth and addressing the associated challenges will be paramount. From managing population density to implementing sustainable infrastructure and addressing environmental concerns, the success of these megacities hinges on effective planning and collaborative efforts on a global scale.
