The Evolving Urban Form: Bangkok

Since 2000, the Bangkok region has experienced annual population growth 2.5 times the rate of growth from 1980 to 2000. By 2010, the Bangkok region – which includes the provincial level city of Bangkok and the provinces of Samat Prakan, Samut Sakhon, Pathum Thani, Nonthaburi and Nakhon Pathom –  was nearing a population of 15 million (Note 1).  read more »

The Evolving Urban Form: Addis Abeba

Addis_0272.jpg

Addis Abeba is the capital of Ethiopia and calls itself the "diplomatic capital" of Africa, by virtue of the fact that the African Union is located here. Yet Ethiopia is still one of the most rural nations in both Africa and the world. Ethiopia also appears to be among the most tolerant. Various forms of Christianity claim account for approximately 65 percent of the population, with the Ethiopian Orthodox Church (Coptic) holding the dominant share. At the same time there is a sizable Muslim minority, at more than 30 percent of the population.  read more »

The Evolving Urban Form: Barcelona

Among those for whom Paris is not their favorite European city, Barcelona often fills the void. Barcelona is the capital of Spain's Catalonia region. Catalonia has been in the news in recent weeks because of the rising a settlement for independence from Spain, or at a minimum, considerably expanded autonomy. In part, the discontent is driven by a concern about the extent to which more affluent Catalonia subsidizes the rest of Spain. Another driving factor is the interest in separating Catalonian language and culture from that of Spain.  read more »

The Evolving Urban Form: Zürich

Zürich is the largest urban area in Switzerland. The core city (stadt) of Zürich is located at the northern end of Lake Zürich, which is glacial and similar to the "finger lakes" of upstate New York. Lake Zürich is approximately 25 miles/40 kilometers long and 1-2 miles/1.5-3 kilometers wide. The urban area extends south along most of the lake and over hills to the East and West and further North.  read more »

Evolving Urban Form: São Paulo

São Paulo is Brazil's largest urban area and ranks among the top 10 most populous in the world. Between 1950 and 1975, São Paulo was also among the globe’s fastest growing urban areas. For two decades starting in 1980 São Paulo ranked fourth in population among the world's urban areas, but has been displaced by much faster growing urban areas like Manila and Delhi.  read more »

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 »
