Evolving Urban Form: Development Profiles of World Urban Areas

The Evolving Urban Form: Istanbul

Istanbul is unique in straddling two continents. The historical city was concentrated on the European side of the Bosporus, the wide, more than 20 mile long strait linking the Sea of Marmara (Mediterranean Sea) in the south to the Black Sea in the north. Nearly all of the historic city was located on a peninsula to the south of the Golden Horn, an inlet off the Bosporus. By 1990, the urban area had expanded to occupy large areas on both sides of the Bosporus.  read more »

Evolving Urban Form: Dhaka

A few weeks ago, we suggested that Hong Kong was the "smart growth" ideal, for having the highest urban population density in the high income world. But, if you expand the universe to the poorer, developing countries, Hong Kong barely holds a candle to Dhaka. Dhaka's 14.6 million people live in just 125 square miles (325 square kilometers). At more than 115,000 people per square mile (Figure 1), or 45,000 per square kilometer (Figure 2), the capital of Bangladesh is nearly 75 percent more dense than Hong Kong.  read more »

The Evolving Urban Form: London

The 2011 census results show that London (the Greater London Authority, which is Inner and Outer London) experienced its greatest percentage population growth in more than 100 years (1891 to 1901). London added nearly 1,000,000 new residents since 2001. That growth, however, is not an indication that "people are moving back to the city." On the contrary, National Statistics data indicates that London lost 740,000 domestic migrants between 2001 and 2011.  read more »

The Evolving Urban Form: Tokyo

Tokyo is the ultimate in urbanization, being nearly one-half larger than any other urban area in the world. Further, Tokyo has retained its position as the largest urban area in the world for longer than any period since London's approximately 100 year run from the early 1800s to the early 1900s. During the 1920s, New York became the largest, but was displaced by Tokyo in 1955.  read more »

The Evolving Urban Form: Cairo

Cairo, Egypt's capital, has long had some of the highest neighborhood population densities in the world. In the 1960s it was reported that one neighborhood had a density of 353,000 people per square mile (136,000 per square kilometer).  read more »

The Evolving Urban Form: Shenzhen

No urban area in history has become so large so quickly than Shenzhen (Note 1). A little more than a fishing village in 1979, by the 2010 census Shenzhen registered 10.4 million inhabitants. It is easily the youngest urban area to have become one of the world's 26 megacities (Figure 1). Most other megacities were the largest urban areas in their nations for centuries (such as London and Paris) and a few for more than a millennium (such as Istanbul and Beijing).  read more »

The Evolving Urban Form: Osaka-Kobe-Kyoto

Osaka-Kobe-Kyoto is Japan's second largest urban area and ranks as the 12th largest urban area in the world. With a population of approximately 17,000,000 and a land area of 1240 square miles (3200 square kilometers), Osaka-Kobe-Kyoto has a population density of 13,700 per square mile (5,200 per square kilometer), making it the most dense major urban area in Japan and among the denser urban areas in the high income world. The larger metropolitan region includes four prefectures, Osaka, Kyoto, Kyoto and Nara (Figure 1).  read more »

The Evolving Urban Form: Ho Chi Minh City (Saigon)

Vietnam may be the next China. With a nominally communist government, Vietnam has liberalized its markets and is prospering from an increased reliance on exports. Vietnam's gross domestic product per capita is still only about $3000, but has been among the faster growing economies over the past 10 years. Vietnam is well positioned to capture any growth that might be diverted from China’s east coast urban areas as labor costs there rise and concerns increase about the influence of that country’s powerful state-owned corporations.  read more »

The Evolving Urban Form: Hong Kong

cox-hongkong-ferry-cover.jpg

Hong Kong has experienced its slowest decadal growth in at least 70 years, according to the results of the recently released 2011 census. Between 2001 and 2011, Hong Kong added only 5.4 percent to its population, a decline of more than two-thirds from its 1991-2001 rate. Hong Kong's slowest growth rate since 1921-1931 was between 1981 and 1991, when 13.8 percent was added to its population. In previous decades growth had been much greater (Figure 1).  read more »

The Evolving Urban Form: Moscow's Auto-Oriented Expansion

Moscow is bursting at the seams. The core city covers more than 420 square miles (1,090 kilometers), and has a population of approximately 11.5 million people. With 27,300 residents per square mile (10,500 per square kilometer), Moscow is one percent more dense than the city of New York, though Moscow covers 30 percent more land. The 23 ward area of Tokyo (see Note) is at least a third more dense, though Moscow's land area is at least half again as large as Tokyo.  read more »
