​​A Gothic cathedral can take centuries to complete. A world exposition pavilion may stand for six months. A ritual structure in Kolkata rises and vanishes within five days. Yet each draws pilgrimage, shapes collective memory, and reorganizes urban life. If heritage has long been defined by what endures, architecture repeatedly shows that cultural authority can also belong to what gathers people.

For much of the twentieth century, conservation frameworks privileged permanence. The Venice Charter, adopted by the International Council on Monuments and Sites, focused on safeguarding monuments and their material authenticity. Cultural value was tied to physical fabric such as stone, brick, and timber. To protect heritage was to preserve what stood. The logic felt stable, even self-evident.

As a result of the nation’s ardent aspirations for growth and development, the social, economic, and physical landscape of India has transformed. A significant portion of the region’s population is of working age and comprises a massive market size, making India a land of opportunity especially in the eyes of foreign investors.

Reflecting this context, multiple mega-cities and mega-projects characterize the built environment and push the nation toward superpower status. On the flip side of the coin, these visionary projects along with the trend of rapid urbanization also bring in a range of side effects - the spread of informal settlements and in turn, the challenges to equitable development.

More than half of the world's population resides in urban areas, with over 4 billion people depending on cities as their main environment. According to the United Nations’ latest report on populations in cities, this number is expected to continue to increase over the next 50 years, prompting cities worldwide to strive to find better ways to accommodate their growing population while transitioning to more sustainable urban practices. To highlight this responsibility, the United Nations has declared July 11th the World Population Day.

Under this year’s theme, “To Leave No One Behind, Count Everyone,” the UN aims to also draw attention to the importance of data collection for reflecting societal diversity. The growth of world cities is part of this equation as an important measure for understanding global population trends. The following list presents the top 20 cities worldwide in 2024, ranked by the population size of their metropolitan areas. Comparing the results to the previous editions, the only cities to reduce their size are the two cities from Japan, Tokyo and Osaka. The highest growth rates can be observed in African mega-cities, Kinshasa and Lagos, while China continues to be the most present country in the list, with 5 metropolises present in the top 20: Shanghai, Beijing, Chongqing, Tianjin, and Guangzhou.

Cities are the bedrock of civilization. For millennia, they have attracted people with the promise of superior standards of living — from better economic and educational opportunities to easier access to quality public infrastructure such as housing, healthcare, and public transport. Today, however, many cities around the world are finding it challenging to live up to this promise. With urban migration accelerating at a dizzying rate – the United Nations projects that over two-thirds of the world's population will live in cities or urban centers by 2050 – existing resources and services in cities are coming under increasing pressure, rendering them dysfunctional and leading to glaring inequities.

There is no singular way to define or assess liveability; every city has a unique set of characteristics, from its history, culture, geography, and demographics, to how it is governed and what urban issues plague it. Therefore, improving liveability requires concerted efforts from multiple stakeholders including people, governments, and experts, to identify critical problem areas and opportunities, and devise contextual solutions. The TV show Tale of Two Cities, where Indian architect and urbanist Dikshu C. Kukreja sits down with global leaders, brings out great insights into what some major cities in the world are doing to create more liveable environments for their inhabitants. Here we present five examples: from Bogotá, Kolkata, Hannover, Tirana, and Washington, D.C.

Half of the world’s population now lives in cities, according to UN-Habitat’s latest reports. While this number is set to increase to two-thirds by 2050, urban challenges are growing exponentially, making it more crucial than ever, to transform our cities. Annually, the world population review assesses the growth of cities and the number of residents living in metropolitan areas, to understand global evolution trends. In 2022, the list of the top 20 most populated countries remained similar to the 2021 edition, with a slight change in numbers and positions. Tokyo kept its status as the world’s largest city, with 37 million inhabitants, while Delhi and Shanghai, followed in second and third positions.

Comparing the results to the 2021 edition, the only decrease that can be seen in the top 20, involves both Japanese cities, Tokyo and Osaka. The rest of the list had, on average, a growth of 1.8% in the total of people residing in metropolitan areas. In fact, African cities Kinshasa in the Democratic Republic of Congo and Lagos in Nigeria gathered the highest rates, with respectively a 4.39% and a 3.54% increase in residents in 1 year. The largest city in the American continent is still Sao Paulo in Brazil, followed closely by Mexico City and Buenos Aires in Argentina, further down the table. In Europe, Istanbul is the most populous, with more than 14.5 million residents.
