As urbanisation accelerates across the globe, the world's biggest cities continue to expand, bringing both economic opportunities and mounting infrastructure challenges. A new global ranking highlights the fastest-growing urban centres, with Asia dominating the list and India emerging as one of the most urbanised nations.
According to a report published by ArchDaily, based on the latest estimates from World Population Review (WPR), Shanghai remains the world's most populous city in 2026 with an estimated population of 24.72 million, followed by Delhi at 23.39 million. The ranking reflects city-level population estimates rather than broader metropolitan or urban agglomeration figures.
Urbanisation reshaping the world
More than half of the world's population now lives in urban areas, a share projected to approach 70% by 2050, according to the report. As cities continue to grow, governments face increasing pressure to improve housing, transportation, public infrastructure, climate resilience and public services.
The report notes that population growth is placing unprecedented demands on mobility networks, public spaces and sustainable urban planning, making architecture and city governance central to future development strategies.
