Jakarta Becomes the World’s Most Populous City, According to New UN Data

Jakarta has become the world's most populous city, according to the World Urbanization Prospects 2025 released by the United Nations Department of Economic and Social Affairs (UN DESA). Using an updated and harmonized method for defining urban areas, the report estimates Jakarta's population at nearly 42 million, placing it ahead of Dhaka, which is about 40 million, and Tokyo, 33 million. The revised ranking illustrates how updated measurement criteria and continued demographic growth are reshaping understandings of urban scale in Asia and globally.

The World's Largest Cities in 2025 by Population

Every year, World Population Day is observed on July 11th, aiming to increase people's awareness of various population issues, such as the importance of urbanization, gender equality, poverty, health, and human rights. In 2025, under the theme "Empowering Youth to Build the Families They Want," the United Nations draws attention to the largest generation of young people in history, many of whom are coming of age in rapidly urbanizing contexts. Urban centers remain key to understanding these demographic patterns, as cities continue to attract populations seeking opportunity, stability, and access to essential services. Today, more than half of the global population resides in urban areas, a share projected to increase to 66% by 2050.

The Urban Transformation of Medellín: A Case Study

CityMakers, The Global Community of Architects Who Learn from Exemplary Cities and Their Makers, is working with Archdaily to publish a series of articles about Barcelona, Medellin, and Rotterdam. The authors are the architects, urban planners, and/or strategists behind the projects that have transformed these three cities and are studied in the "Schools of Cities" and "Documentary Courses" made by CityMakers. On this occasion, Victor Restrepo, Coordinator of CityMakers in Medellin, presents his article "Medellin: A Case Study".

Medellín stands as an inspiring example for many cities worldwide. It is a city that transitioned from deep collective fear to hopeful enthusiasm for urban and social life characterized by quality and coexistence. The city's crisis has always been associated with violence and drug trafficking. However, this crisis is more structural and profound, it responds to many more factors, some of which are associated with the accelerated growth of its population, as in many Latin American cities.

The Barcelona Model: Public Space as a Synonym for Urban Adaptation

CityMakers, The Global Community of Architects Who Learn from Exemplary Cities and Their Makers, is working with Archdaily to publish a series of articles about Barcelona, Medellin, and Rotterdam. The authors are the architects, urban planners, and/or strategists behind the projects that have transformed these three cities and are studied in the "Schools of Cities" and "Documentary Courses" made by CityMakers. On this occasion, Jaume Barnada, coordinator of the award-winning Climate Shelters project in Barcelona schools and speaker at the "Schools of Cities", presents his article "Barcelona, the public place as a synonym for the adaptation of the built city."

Cities are dense, built spaces in which pavements have been efficiently imposed on the natural soil. Cities like Barcelona have almost 75% of the land paved and waterproof. Without a doubt, it is an excess to reverse at a time of climate emergency, where we must reconnect with nature. Oriol Bohigas [1] told us that good urbanization had paved the squares of Mediterranean cities and that no one wanted to live in a mudhole. I'm sure he was right. Also, he taught us that the green and, consequently, the natural soil had to have dimension and especially an urban position. Squares are squares and parks are parks, and each space has a type of project. Today, concepts are too frequently confused when urbanizing public places and consequently, we find projects that blur the model.
