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 »
Evolving Urban Form: Development Profiles of World Urban Areas
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 »
Few terms are more misunderstood than "urban sprawl." Generally, it refers to the spatial expansion (dispersion) of cities and has been use to describe urbanization from the most dense (least sprawling) in the world (Dhaka, Bangladesh), the most dense in the United States (Los Angeles) and also the least dense in the world (such as Atlanta and Charlotte, read more »
Tianjin is located on Bohai Gulf, approximately 75 miles (120 kilometers) from Beijing. It was the imperial port of China, by virtue of that proximity. Tianjin also served as one of the most important "treaty ports" occupied and/or controlled by western nations and Japan for various years before 1950. read more »
No city in the world is so misunderstood by analysts and the press. It is commonly asserted Chongqing is the largest city in the world. In reality it barely makes the top 50, ranking 47th.
Cities (Shi) in China are Regions and Mostly Rural
It is fundamentally a problem of semantics and a failure to comprehend the nuances of urban geography in China. The country is divided into provinces and their equivalents, which are in turn, divided into prefectures, most of which are "shi," "Shi" translates into English as "city." read more »
Philadelphia was America's first large city and served as the nation's capital for all but nine months between the inauguration of George Washington is the first president in 1789 and the capital transferred to Washington, DC in 1800.
Before the early 1900s, the United States Census Bureau had not developed a metropolitan area (labor market area) concept. However, the website peakbagger.com has attempted to define earlier metropolitan areas based on concepts similar to those used today. In the case of Philadelphia, this is important, because it was somewhat unique in having virtually adjacent, highly populated suburbs that make comparisons of municipal populations (the only population data available) misleading. read more »
There is an increasing recognition – at least outside the academy, planning organization and urban core developer groups – that the spatial expansion of cities or suburbanization represents the evolving urban form of not only the United States and virtually all of the high income world but also across the developing world, whether middle income or third world. read more »
Despite planning efforts to restrict it, the Bay Area continues to disperse. For decades, nearly all population and employment growth in the San Jose-San Francisco Combined Statistical Area has been in the suburbs, rather than in the core cities of San Francisco and Oakland. The CSA (Note) is composed of seven adjacent metropolitan areas (San Francisco, San Jose, Santa Cruz, Santa Rosa, Vallejo, Napa, and Stockton). A similar expansion also occurred in the New York CSA. read more »
There may be no better example of the post World War II urban form than Charlotte, North Carolina (a metropolitan area and urban area that stretches into South Carolina). Indeed, among the approximately 470 urban areas with more than 1 million population, Charlotte ranks last in urban population density in the United States (Figure 1) and last in the world. According to the United States Census Bureau, Charlotte's built-up urban area population density was 1685 per square mile (650 per square kilometer) in 2010. read more »
The term “Greater New York” was applied, unofficially, to the 1898 consolidation that produced the present city of New York, which brought together the present five boroughs (counties). The term “Greater” did not stick, at least for the city. When consolidated, much of the city of New York was agricultural. As time went on, the term "Greater" came to apply to virtually any large city and its environs, not just New York and implied a metropolitan area or an urban area extending beyond city limits. read more »
