Demographics

Midcentury modern tours now are taking place in cities all over the country. Renewed interest in this era capitalizes on the millennials’ interest in design from a time that seems almost impossibly optimistic compared to today’s zeitgeist. Most cities around the country boast a healthy building stock from this postwar period, nicknamed “the suburbs,” although these are ritually condemned – and designated for annihilation – by academics, urban land speculators and the urban clerisy.  read more »

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 »

Many global population projections point to the current world population of roughly seven billion people peaking at around nine to ten billion in 2050, after which numbers will slowly decline. In the midst of this growth, Australia’s current population of 23 million is predicted to rise to around 30 or 35 million in the same period. This low growth outlook has been called ‘big Australia.’ We are kidding ourselves, aren’t we?  read more »

The Federation of Canadian Municipalities (FCN) and the Canadian Urban Transit Association (CUTA) have expressed serious concern about generally longer commute trip times making Canadian metropolitan areas less competitive. Each has called for additional funding for transit at the federal level to help reduce commute times and improve metropolitan competitiveness.  read more »

The Midwest’s troubles are well-known. The decline of manufacturing has resulted in job losses and dying industrial towns. The best and brightest have fled the flatlands for more exciting, sunnier, mountainous, or coastal places where the real action is. Even Peyton Manning has left the heartland for the Rockies.  read more »

California Senate President Pro-Tem Darrell Steinberg countered my Wall Street Journal commentary California Declares War on Suburbia in a letter to the editor (A Bold Plan for Sustainable California Communities) that could be interpreted as suggesting that all is well in the Golden State.  read more »

Population change has short run and long run effects. Short run effects include changes in fertility rates that can result from economic fluctuations. For example, during a recession, couples may delay having children until economic conditions improve.  Once job growth has begun and expectations rise, birthrates can increase The correlation is not perfect and other demographic factors could come into play.     read more »

The latest edition of Demographia World Urban Areas has just been released. The publication includes population estimates, urban land area estimates and urban densities for all nearly 850 identified urban areas in the world with a population of 500,000 or more. These urban areas account for approximately 48% of the world's urban population. Overall, data is provided for approximately 1500 urban areas, comprising approximately 1.9 billion people, or 52% of the world's urban population.  read more »

The recent release of the 2010 US census data on urban areas (Note 1) shows that Americans continue to prefer their lower density lifestyles, with both suburbs and exurbs (Note 2) growing more rapidly than the historic core municipalities.  This may appear to be at odds with the recent Census Bureau 2011 metropolitan area population estimates, which were widely mischaracterized as indicating exurban (and suburban) losses and historical core municipality gains.  read more »

Jean Gottman in 1961 coined the term megalopolis (Megalopolis, the Urbanized Northeastern Seaboard of the Unites States) to describe the massive concentration of population extending from the core of New York north beyond Boston and south encompassing Washington DC. It has been widely studied and mapped, including by me. (Morrill, 2006, Classic Map Revisited, Professional Geographer).  The concept has also been extended to describe and compare many other large conurbations around the world.

Maybe it’s time to see how the original has fared?   And what has happened to other metropolitan complexes in the US, most notably Los Angeles, San Francisco, Chicago and should we say Florida?  read more »
