Global Metropolitan Population Growth Since 1950

The rapid urbanization of the last seventy years has fundamentally transformed the global demographic landscape, shifting the concentration of the worlds largest megacities from the developed West and Japan toward the emerging economies of Asia and Africa. In 1950, New York and Tokyo were the only metropolitan areas with populations exceeding 10 million residents. Today, dozens of cities have surpassed this threshold, with Delhi and Tokyo leading the world in total scale. The growth has been most dramatic in South Asia and China, where cities like Delhi and Shanghai have each added more than 22 million residents since the mid 20th century.

Emerging metropolises in Africa and Southeast Asia have also seen explosive expansion. Lagos and Kinshasa have evolved from modest administrative centers into massive urban hubs of over 14 million people, while Dhaka has added over 20 million residents to become one of the worlds most densely populated urban areas. Shenzhen represents a unique case of rapid industrialization, growing from a small fishing village in the late 1970s to a global technology capital with more than 12 million inhabitants. While established cities such as Los Angeles and New York have continued to grow, their total expansion is significantly outpaced by the newer megacities of the Global South.
