When asked to name the world’s largest city, most people immediately think of global icons like New York, Tokyo, or Mexico City. These metropolises dominate our urban imagination with their sprawling skylines and dense populations. However, the title of world’s largest city—both by area and potentially by population—belongs to a place many Westerners have never heard of: Chongqing, China. This massive urban center challenges our very understanding of what constitutes a city in the 21st century.
Discovering Chongqing: a megacity of unprecedented scale
Nestled at the confluence of the Yangtze and Jialing rivers in south-central China, Chongqing sprawls across an astonishing 82,400 square kilometers—larger than entire countries like Austria, Ireland, or Panama. This municipal area represents approximately 15% of China’s mainland territory, making it a true urban giant on the global stage.
Unlike conventional megacities built on relatively flat terrain, Chongqing’s development follows the region’s dramatic topography. The city rises and falls across mountains and valleys, creating a three-dimensional urban landscape unlike anywhere else on Earth. British journalist Oliver Wainwright describes roads winding along cliff faces, subway lines passing through buildings, and cable cars connecting rooftops to valleys below.

The vertical nature of Chongqing creates surreal urban experiences. Residents and visitors navigate complex networks of elevated walkways, underground passages, and buildings that seem to defy gravity as they cling to steep hillsides. This unique geography has earned Chongqing nicknames like “Mountain City” and “Fog Capital,” reflecting both its topographical challenges and atmospheric conditions.
The city’s population statistics are equally staggering. Home to approximately 32 million people—comparable to Canada’s entire population—Chongqing exemplifies China’s massive urbanization push. While the municipal boundaries include rural areas, over 70% of residents live in urban zones, creating one of the world’s most populous metropolitan regions. The city’s growth mirrors China’s broader transformation from a nation implementing ambitious infrastructure projects to an increasingly urbanized global power.
The remarkable transformation of a historic center
While Chongqing’s modern scale might suggest a newly created metropolis, this couldn’t be further from the truth. The city boasts over 3,000 years of continuous history, serving various crucial roles throughout China’s development. Long before its current incarnation, Chongqing functioned as a capital city, strategic Yangtze River port, and major commercial hub.
During World War II, when much of eastern China fell under Japanese occupation, Chongqing served as the provisional capital of the Chinese government. This historical significance adds layers of cultural depth to what might otherwise be seen as simply another product of China’s rapid modernization. Unlike certain planned cities that seem to emerge overnight, Chongqing represents an organic evolution spanning millennia.

The city’s demographic explosion began in earnest during the 1970s, when its population hovered around 2.3 million residents. By 1997, that number had skyrocketed to nearly 29 million, reflecting China’s broader policy of accelerated urbanization. Today, Chongqing serves as a pivotal logistics center for inland China and symbolizes the country’s economic transformation.
Visitors to Chongqing often report feeling overwhelmed by its scale and complexity. The city presents a fascinating juxtaposition of ancient temples nestled among futuristic skyscrapers, traditional street markets operating in the shadows of luxury shopping centers, and rural villages gradually absorbed by expanding urban districts. This creates a unique urban experience that differs significantly from exploring more familiar Western cities with their typically more uniform development patterns.
Why the world’s largest city remains relatively unknown
Despite its enormous size and importance, Chongqing remains remarkably obscure to most Westerners. Several factors contribute to this curious anonymity. First, pronunciation challenges make the name less memorable to non-Chinese speakers. Without frequent media exposure, places with unfamiliar names simply fail to register in our geographic consciousness.
Second, statistical presentation often obscures Chongqing’s urban reality. Because its population spreads across such vast territory, density figures can be misleading when compared to more compact cities. This leads many analysts to misclassify Chongqing as primarily rural, despite its massive urban core.

Third, China’s dramatic urban transformation has happened so rapidly that international awareness hasn’t kept pace. While Beijing and Shanghai have established global identities, inland cities like Chongqing haven’t received comparable attention in Western media. This knowledge gap persists even as the city develops infrastructure projects that would make headlines if constructed elsewhere.
Finally, tourism patterns reinforce this obscurity. International visitors to China typically focus on Beijing, Shanghai, and Xi’an with their iconic attractions, while Chongqing remains primarily a domestic tourism destination. This limited exposure continues despite the region hosting natural wonders that could rival major global attractions, including sites that may one day face environmental challenges from natural phenomena if climate conditions change dramatically.
The future of megalopolis development
Chongqing offers a fascinating case study in 21st-century urban evolution. China’s urbanization rate has jumped from just 36% in 2002 to projections approaching 70% by 2050—representing a migration of over 300 million people. This unprecedented demographic shift makes Chinese cities the laboratories where tomorrow’s urban solutions must be developed and tested.
The challenges facing Chongqing mirror those confronting many rapidly growing urban areas worldwide: environmental sustainability, infrastructure capacity, social cohesion, and quality of life. Yet the scale at which Chongqing must address these issues far exceeds that of most other cities. Its solutions may provide valuable lessons for urban planners globally.
Innovative approaches already visible in Chongqing include vertical transportation networks that efficiently move people through mountainous terrain, mixed-use developments that reduce commuting needs, and urban agriculture initiatives that bring food production closer to consumers. These adaptations respond directly to the unique geographical constraints that make Chongqing so different from coastal megacities.
As climate change reshapes habitable regions, cities may increasingly need to develop in previously overlooked areas with challenging topography. Chongqing’s experience navigating such constraints could prove invaluable. Similarly, as unexpected environmental developments surprise scientists and planners alike, adaptable urban systems like those emerging in Chongqing may offer greater resilience.
While other unusual property opportunities occasionally make headlines, such as small islands with unique purchase conditions, Chongqing represents something far more significant: a glimpse into how urbanization may evolve when traditional constraints are reimagined. As cities worldwide face increasing pressure to house growing populations while reducing environmental footprints, Chongqing’s vertical development strategies could become increasingly relevant.
From navigating urban wildlife encounters (a challenge very different from when wild animals surprise shoppers in smaller communities) to managing massive infrastructure networks, Chongqing demonstrates how cities of unprecedented scale might function. Whether this model represents the future of urban living or an extraordinary exception, Chongqing deserves far greater recognition as one of humanity’s most remarkable urban achievements—a city that defies convention in almost every way imaginable.
