Evolving Urban Form: Development Profiles of World Urban Areas

The Evolving Urban Form: Madrid

Cuatro_Torres_Business_Area.JPG

Madrid is the capital of Spain, as well as its largest built-up urban area, with an estimated 6.4 million population in 2018. Madrid’s urban area plus economically connected rural and small town areas make up the metropolitan area, which has nearly 7,000,000 residents. The area has an urban population density of 4,700 per square kilometer (12,200 per square mile), ranking it third among the European Union’s built-up urban areas over 1,000,000 population.  read more »

World Urban Areas: 1,064 Largest Cities: 2018 Update

portrait 2018 cover.png

This year, as in 2017, there are 37 megacities --- urban areas estimated to have more than 10 million residents. The 20 largest urban areas are indicated in Figure 1. Tokyo-Yokohama continued to be the largest, as it has been for more than six decades. Second ranked Jakarta and third ranked Delhi continue to edge up on Tokyo-Yokohama. Even if their much faster growth were to continue at the current rate, neither would assume the top position over Tokyo-Yokohama until after 2030.  read more »

The Evolving Urban Form: Paris

Probably no city inspires the romance of Paris, which has been a principal object of writers for centuries. The Paris they have written about is limited almost exclusively to the small geography of the ville de Paris, which has expanded from 1.7 square miles (4.3 square kilometers) in the 14th century to 40.5 square miles (105.0 square kilometers) in 1860, its latest annexation (Note). The ville de Paris is however, by no means all of Paris, representing less than four percent of the land in the built-up urban area, and little more than 0.5 percent of the metropolitan area.  read more »

The Evolving Urban Form: Prague

Prague is the capital of Czechia, a nation most readers have probably never heard of. Last year, the Czech Republic adopted a new name that does not reveal its governance structure (republic). The new name has not enjoyed widespread acclaim. The union of Czechoslovakia, which dates from the end of World War I, split peacefully in 1993, resulting in the creation of Czech Republic and Slovakia.  read more »

The Evolving Urban Form: Budapest

The Budapest area has lost population overall since 1980, having fallen from 3.03 million to 2.99 million in 2016, according to Hungarian Central Statistical Office data as reported by citypopulation.de (Graphic 1). This 1.3 percent loss is smaller than the national population loss over the same period of 8.2 percent. Moreover, during the last five years, the Budapest area is estimated to have gained 1.7 percent, even as Hungary lost 1.1 percent.  read more »

The Evolving Urban Form: Warsaw

Like other major cities in the high income world, Warsaw has seen central area population losses, with all of the population growth taking place outside the urban core, principally in the suburbs and exurbs (Graphic 1). The city's districts were reconfigured so that direct comparisons cannot be made before the 2002 census.  read more »

The Evolving Urban Form: Houston

Houston is a city (metropolitan area) of superlatives. The most recent Brookings Institution data shows that Houston has the seventh strongest per capita economy (gross domestic product) in the world (Figure 1). This places Houston above New York and more surprisingly, perhaps, other cities perceived to have strong economies are far below Houston and outside of the top 10, such as London, Tokyo and Chicago.  read more »

Surprising Ordos: The Evolving Urban Form

Ordos, in China's Autonomous Region of Inner Mongolia (equivalent to a province) has received international notoriety as a "ghost city." I had already visited one other ghost city and found the reports considerably exaggerated (The Zhengzhou New Area in Henan, a commercial and residential district). But Ordos has received by far the most publicity.  read more »

The Evolving Urban Form: Detroit

Probably no city in the high income world evokes impressions of urban decline more than Detroit --- and for good reason. The core city of Detroit has lost more of its population than any developed world city of more than 500,000 since 1950. The city's population peaked at 1,850,000 residents in 1950 and at its decline rate since 2010 could drop below 650,000 residents by 2020 census.  read more »

The Evolving Urban Form: Jing-Jin-Ji (Dispersing Beijing)

Tangshan.jpg

China's cities continue to add population at a rapid rate, despite a significant slowdown in population growth. Although overall population is expected to peak around 2030, the urban population will continue growing until after 2050. China’s cities will be adding more than 250 million new residents in the next quarter century, according to United Nations projections. China's cities will add nearly as many people as live in Indonesia, the world's fourth largest country, more than live in Brazil and 10 times as many as live in Australia.  read more »
