The most populated cities capture the attention of researchers and policymakers. These cities have become economic, cultural, and political hubs that directly influence the global economy.
With ongoing population growth and urban expansion, major cities are attracting millions seeking job opportunities, services, and education, leading to the emergence of "megacities."
Why Are Big City Populations Increasing?
In past decades, the world has seen an unprecedented wave of urbanization, with millions moving from rural to urban areas due to job concentrations and access to healthcare and education in urban centers.
Moreover, economic and technological advancements have enhanced the allure of major cities, causing continuous expansion. However, these cities face challenges like traffic congestion, housing, natural resources, and infrastructure issues.
How Are City Populations Counted?
Most global rankings use the "urban agglomeration" or "metropolitan area" concept, encompassing the main city and economically and socially linked surrounding areas. Thus, figures may differ from administrative city populations.
Urban population growth isn't only tied to birth rates but is also influenced by internal and external migration, leading to significant population spikes in short periods.

Future Challenges for Megacities

Many governments are investing in smart cities, modern transport networks, and environmental sustainability to ensure these urban centers can grow without compromising life quality.
